THE 0.5-2.22 {mu}m SCATTERED LIGHT SPECTRUM OF THE DISK AROUND TW Hya: DETECTION OF A PARTIALLY FILLED DISK GAP AT 80 AU  

SciTech Connect (OSTI)

We present a 0.5-2.2 {mu}m scattered light spectrum of the circumstellar disk around TW Hya from a combination of spatially resolved Hubble Space Telescope STIS spectroscopy and NICMOS coronagraphic images of the disk. We investigate the morphology of the disk at distances >40 AU over this wide range of wavelengths, and identify the presence of a depression in surface brightness at {approx}80 AU that could be caused by a gap in the disk. Additionally, we quantify the surface brightness, azimuthal symmetry, and spectral character of the disk as a function of radius. Our analysis shows that the scattering efficiency of the dust is largely neutral to blue over the observed wavelengths. We model the disk as a steady {alpha}-disk with an ad hoc gap structure. The thermal properties of the disk are self-consistently calculated using a three-dimensional radiative transfer code that uses ray tracing to model the heating of the disk interior and scattered light images. We find a good fit to the data over a wide range of distances from the star if we use a model disk with a partially filled gap of 30% depth at 80 AU and with a self-similar truncation knee at 100 AU. The origin of the gap is unclear, but it could arise from a transition in the nature of the disk's dust composition or the presence of a planetary companion. Based on scalings to previous hydrodynamic simulations of gap-opening criteria for embedded proto-planets, we estimate that a planetary companion forming the gap could have a mass between 6 and 28 M{sub Circled-Plus }.

b -> s mu+ mu- and b -> mu+ mu- At the LHC  

E-Print Network [OSTI]

With their 2010-2011 data set, the LHC experiments have started their quest to observe the rare decays B0_{s/d} -> mu+ mu-. This study will provide very sensitive probes of New Physics (NP) effects. NP discovery potential lies as well in the study of the decay B0_d -> K*0 mu+ mu-. Results and perspectives are presented for studies at the LHC of rare B decays involving flavor changing neutral currents.

A muon that does not follow the traditional weak- force decay pattern into a lighter electron and two neutrinos, but converts wholly into an electron. WHAT WILL THIS TELL US ABOUT THE WORLD? * Observing Mu2e conversion would point the way to a unification of all the forces of nature controlling the interactions of matter. This unification of the four existing forces we observe today - gravity, the electromagnetic force, and the weak and strong forces - is considered Albert Einstein's dream of "grand unification. * Finding signs of this "grand unification" could explain how the universe evolved from being

After the feasibility of vacuum isolated [mu][sup -]d production was demonstrated at TRIUMF in 1989, development was begun on a target system that would take advantage of the process to aid in the understanding of the muon catalyzed fusion cycle. Minimal neutron backgrounds, the ability to use silicon detectors, and compatibility with tritium were considered important for a very versatile target system. the advantages which the target gives isolating [mu]CF process will be outlined.

From a {nu} factory to {mu} super + mu super {minus} Colliders  

SciTech Connect (OSTI)

An important feature of a {mu}-storage ring {nu}-source is that it can be extended to the possibility of a future high-energy muon collider. The neutrino source provides a useful physics device that initiates key technologies required for future {mu}{sup +}-{mu}{sup {minus}} Colliders, but with much less demanding parameter requirements. These technologies include high-intensity {mu}-production, {mu}-capture, {mu}-cooling, {mu}-acceleration and multiturn {mu} storage rings. {mu}{sup +}-{mu}{sup {minus}} colliders require a similar number of muons, but they require that the muons be cooled to a much smaller phase space and formed into a small number of bunches, and both positive and negative bunches must be simultaneously captured. These differences are discussed, and the extension of the {nu}-source to {mu}{sup +}-{mu}{sup {minus}} collider specifications is described.

Search for $B_s \\to \\mu^+\\mu^-$ and $B_d \\to \\mu^+\\mu^-$ Decays with CDF II  

SciTech Connect (OSTI)

A search has been performed for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} decays using 7 fb{sup -1} of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. The observed number of B{sup 0} candidates is consistent with background-only expectations and yields an upper limit on the branching fraction of {Beta}(B{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 6.0 x 10{sup -9} at 95% confidence level. We observe an excess of B{sub s}{sup 0} candidates. The probability that the background processes alone could produce such an excess or larger is 0.27%. The probability that the combination of background and the expected standard model rate of B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} could produce such an excess or larger is 1.9%. These data are used to determine {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}) = (1.8{sub -0.9}{sup +1.1}) x 10{sup -8} and provide an upper limit of {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 4.0 x 10{sup -8} at 95% confidence level.

Coulombic and radiative decay rates of the resonances of the exotic molecular ions pp{mu}, pp{pi}, dd{mu}, dd{pi}, and dt{mu}  

SciTech Connect (OSTI)

The bound levels and the resonances (energy and width of the excited levels) of pp{mu}-like exotic molecules for J=0 total angular momentum have been computed with an accuracy in the 10{sup -11} a.u. range, by numerical diagonalization of the complex rotated Hamiltonian in a variational sturmian basis set. For the resonances below the N=2 dissociation threshold, the x-ray spontaneous emission spectrum is computed from the wave functions. The radiative decay rate of the first resonance of pp{mu} is found to be 0.0713 ps{sup -1}, close to half that of a p{mu}(2p) atom, as expected in a simple Born-Oppenheimer picture of a resonance.

Measurement of the Forward-Backward Asymmetry in the $B \\to K^{(*)} \\mu^+ \\mu^-$ Decay and First Observation of the $B^0_s \\to \\phi \\mu^+ \\mu^-$ Decay

We reconstruct the rare decays B{sup +} {yields} K{sup +} {mu}{sup +}{mu}{sup -}, B{sup 0} {yields} K*(892){sup 0} {mu}{sup +}{mu}{sup -}, and B{sub s}{sup 0} {yields} {phi}(1020){mu}{sup +}{mu}{sup -} in a data sample corresponding to 4.4 fb{sup -1} collected in p{bar p} collisions at {radical}s = 1.96 TeV by the CDF II detector at the Fermilab Tevatron Collider. Using 120 {+-} 16 B{sup +} {yields} K{sup +} {mu}{sup +}{mu}{sup -} and 101 {+-} 12 B{sup 0} {yields} K*{sup 0} {mu}{sup +}{mu}{sup -} decays we report the branching ratios. In addition, we report the measurement of the differential branching ratio and the muon forward-backward asymmetry in the B{sup +} and B{sup 0} decay modes, and the K*{sup 0} longitudinal polarization in the B{sup 0} decay mode with respect to the squared dimuon mass. These are consistent with the theoretical prediction from the standard model, and most recent determinations from other experiments and of comparable accuracy. We also report the first observation of the B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -} decay and measure its branching ratio {Beta}(B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -}) = [1.44 {+-} 0.33 {+-} 0.46] x 10{sup -6} using 27 {+-} 6 signal events.

Updated Search for $B_s \\to \\mu^+$ mu- at CDF  

SciTech Connect (OSTI)

The decay B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} is very sensitive to contributions from new physics processes. Thus the Tevatron and LHC experiments are hunting for an observation of a B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} signal. In this article the updated search for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} by the CDF experiment is presented. The CDF result was received with great interest because an excess over the background expectation is seen, although of modest statistical significance and still consistent with the prediction of a standard model signal and other experimental results.

The next generation of $\\mu\\ -> e \\gamma$ and $\\mu\\ -> 3e$ CLFV search experiments  

E-Print Network [OSTI]

We explore the possibilities for extending the sensitivity of current searches for the charged lepton flavor violating decays $\\mu\\ -> e \\gamma$ and $\\mu\\ -> eee$. A future facility such as Project X at Fermilab could provide a much more intense stopping $\\mu^+$ beam, facilitating more sensitive searches, but improved detectors will be required as well. Current searches are limited by accidental and physics backgrounds, as well as by the total number of stopped muons. One of the limiting factors in current detectors for $\\mu\\ -> e \\gamma$ searches is the photon energy resolution of the calorimeter. We present a new fast Monte Carlo simulation of a conceptual design of a new experimental concept that detects converted $e^+e^-$ pairs from signal photons, taking advantage of the improved energy resolution of a pair spectrometer based on a silicon charged particle tracker. We also study a related detector design for a next generation $\\mu\\to eee$ search experiment.

Producing {mu}{sup {minus}}d and {mu}{sup {minus}}t in vacuum  

SciTech Connect (OSTI)

After the feasibility of vacuum isolated {mu}{sup -}d production was demonstrated at TRIUMF in 1989, development was begun on a target system that would take advantage of the process to aid in the understanding of the muon catalyzed fusion cycle. Minimal neutron backgrounds, the ability to use silicon detectors, and compatibility with tritium were considered important for a very versatile target system. the advantages which the target gives isolating {mu}CF process will be outlined.

CP violation of Extended Higgs sector and Its impact on D^0 -> mu^+ mu^- decay  

E-Print Network [OSTI]

We study the impact of the CP violation of the extra Higgs sector on $D^0$ decay. The CP even and CP odd neutral Higgs mixing of the two Higgs doublet model is studied and we show how the CP violating effect of the mixing may lead to the longitudinal muon polarization asymmetry of $D^0 \\to \\mu^+ \\mu^-$. The asymmetry of the short-distance contribution is sensitive to the CP violating phase of the extended Higgs sector.

Channeling of positrons from. mu. /sup +/ decay  

SciTech Connect (OSTI)

The first attempt to observe the steering or channeling effect of a host crystal lattice on the trajectories of decay positrons from interstitial positive muons is described. An enhanced (flux peaking) or diminished (blocking) positron counting rate for emission along a low index crystalline axis would be evidence of such an effect and would help to determine the lattice location of the emitting muon. The expected angular widths of these features is approximately 0.2/sup 0/. A 29.8 MeV/c surface ..mu../sup +/ beam was stopped in a high quality silicon crystal wafer which was elastically bent to a good approximation to a spherical cap. This brought the (100) axes, which were initially normal to the wafer surface, to a focus at the radius of curvature R = 110 cm. The normalized e/sup +/ rate was measured as a function of position with a small two-counter scintillation telescope which was moved through the focus. We found no evidence for channeling at the 17% level, suggesting that the ..mu../sup +/ in Si either (1) makes large vibratory excursions, (2) occupies a site of low symmetry, or (3) occupies one of several possible inequivalent stopping sites.

Time evolution of relativistic d + Au and Au + Au collisions  

E-Print Network [OSTI]

The evolution of charged-particle production in collisions of heavy ions at relativistic energies is investigated as function of centrality in a nonequilibrium-statistical framework. Precise agreement with recent d + Au and Au + Au data at sqrt(s_NN) = 200 GeV is found in a Relativistic Diffusion Model with three sources for particle production. Only the midrapidity source comes very close to local equilibrium, whereas the analyses of the overall pseudorapidity distributions show that the systems remain far from statistical equilibrium.

Charmed hadron production at low transverse momentum in Au+Au collisions at RHIC  

E-Print Network [OSTI]

We report measurements of charmed hadron production from hadronic ($D^{0}\\rightarrow K\\pi$) and semileptonic ($\\mu$ and $e$) decays in 200 GeV Au+Au collisions at RHIC. Analysis of the spectra indicates that charmed hadrons have a different radial flow pattern from light or multi-strange hadrons. Charm cross sections at mid-rapidity are extracted by combining the three independent measurements, covering the transverse momentum range that contributes to $\\sim$90% of the integrated cross section. The cross sections scale with number of binary collisions of the initial nucleons, a signature of charm production exclusively at the initial impact of colliding heavy ions. The implications for charm quark interaction and thermalization in the strongly interacting matter are discussed.

Lepton flavor violating processes \\tau ->\\mu\\gamma$, $\\tau-> 3\\mu$ and $Z-> \\mu\\tau$ in the Supersymmetric economical 3-3-1 model  

E-Print Network [OSTI]

In this work, we study the charged lepton flavor violating (cLFV) decays $\\tau-> \\mu\\gamma$, $\\tau-> 3\\mu$ and $Z->\\mu\\tau$ in the framework of the Supersymmetric economical 3-3-1 model. Analytic formulas for branching ratios (BR) of these decays are presented. We assume that there exist lepton flavor violation (LFV) sources in both right- and left-handed slepton sectors. This leads to the strong enhancement of cLFV decay rates. We also show that the effects of the LFV source to the cLFV decay rates in the left-handed slepton sector are greater than those in the right- handed slepton sector. By numerical investigation, we show that the model under consideration contains the relative light mass spectrum of sleptons which satisfies the current experimental bounds on LFV processes in the limit of small $\\tan \\gamma$. The interplay between monopole and dipole operators also was studied.

We also find event shapes to be close to spherical in the most central collisions, independent of bombarding energy and fragment mass up to {sup 4}He.

The effect of low Au concentrations on the properties of eutectic Sn/Pb  

SciTech Connect (OSTI)

This study was of the effects moderately low Au concentrations ({le} 10 wt%) have on the mechanical properties and microstructure of an eutectic Sn/Pb alloy. Vibration (60--90 Hz swept sine wave for 30 hours) and thermal cycling (0--110C for 1450 cycles) reliability tests were performed on fine pitch leaded chip carriers using eutectic Sn/Pb solder on PCBs (printed circuit boards) with 0, 5, 10, 20, and 50{mu}in nominal Au thicknesses. Testing was also performed on double shear creep specimens consisting of arrays of regular pitch joints. There was a dramatic increase in the number of joints containing voids with increasing Au concentration, an effect more pronounced in the creep joints than in the reliability joints. These voids tended to coalesce and grow during rework simulation of the reliability joints. AuSn{sub 4} intermetallics present in toe of 4.8 wt% (50 {mu}in) Au vibration joints rotated from initial vertical perpendicular to surface of PCB metallization, solidification positions to roughly horizontal (parallel to plating surface) orientations during rework simulation and during aging of the parts. The AuSn{sub 4} intermetallics in the toe of the 4.8 wt% (50{mu}in) Au reflowed joints also rotated after vibration testing. No joint failures were observed in either vibration tested or thermally cycled specimens. Cracks formed in some of the vibration tested specimen joints under the heel of the gull-wing lead at Pb-rich phases. Thermally cycled specimens showed eutectic microstructure and intermetallic coarsening without crack formation. Creep tests showed loss of the superplasticity in eutectic Sn/Pb alloys with even the lowest Au concentration tested of 0.2 wt% Au. Intermetallic rotation was not a factor in crack propagation, but void presence was. Cracks tended to form in joints containing voids before forming in void-free joints. Crack propagation followed Sn/Sn grain boundaries and Sn/Pb phase boundaries from Pb-rich phase to Pb-rich phase.

Solenoid magnet system for the Fermilab Mu2e experiment  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

The Fermilab Mu2e experiment seeks to measure the rare process of direct muon to electron conversion in the field of a nucleus. Key to the design of the experiment is a system of three superconducting solenoids; a muon production solenoid (PS) which is a 1.8 m aperture axially graded solenoid with a peak field of 5 T used to focus secondary pions and muons from a production target located in the solenoid aperture; an 'S shaped' transport solenoid (TS) which selects and transports the subsequent muons towards a stopping target; a detector solenoid (DS) which is an axially graded solenoid at the upstream end to focus transported muons to a stopping target, and a spectrometer solenoid at the downstream end to accurately measure the momentum of the outgoing conversion elections. The magnetic field requirements, the significant magnetic coupling between the solenoids, the curved muon transport geometry and the large beam induced energy deposition into the superconducting coils pose significant challenges to the magnetic, mechanical, and thermal design of this system. In this paper a conceptual design for the magnetic system which meets the Mu2e experiment requirements is presented.

$\\mu$-$\\tau$ reflection symmetry and radiative corrections  

E-Print Network [OSTI]

The $\\mu$-$\\tau$ reflection symmetry is compatible with current neutrino oscillation data and easily realized under family symmetries. We prove that this symmetry preserves $\\theta_{23}=45^\\circ$, $\\delta=\\pm90^\\circ$, $\\rho,\\sigma=0,90^\\circ$, and can be embedded into the seesaw mechanism. The $\\mu$-$\\tau$ reflection symmetry preserved at a high energy scale $\\Lambda_\\text{FS}$ will be broken by radiative corrections and result in deviations of $\\theta_{23}$ from $45^\\circ$ and $\\delta$ from $\\pm90^\\circ$ at the electroweak scale. We develop an analytical method to derive the corrections to all the mixing parameters. We perform a numerical analysis in the MSSM for $\\delta=-90^\\circ$ at $\\Lambda_\\text{FS}$, and observe that $\\theta_{23}>45^\\circ$ in the normal mass ordering, $\\theta_{23}<45^\\circ$ in the inverted mass ordering, and the sizable correction to $\\delta$ prefers a negative sign. These deviations have definite directions and can be tested in the future neutrino oscillation experiments.

Analysis of D+ to K- pi+ e+ nu_e and D+ to K- pi+ mu+ nu_mu Semileptonic Decays  

E-Print Network [OSTI]

Using a large sample (~11800 events) of D^+ into K^- pi^+ e^+ nu_e and D^+ into K^- pi^+ mu^+ nu_mu decays collected by the CLEO-c detector running at the psi(3770), we measure the helicity basis form factors free from the assumptions of spectroscopic pole dominance and provide new, accurate measurements of the absolute branching fractions for D^+ into K^- pi^+ e^+ nu_e and D^+ into K^- pi^+ mu^+ nu_mu decays. We find branching fractions which are consistent with previous world averages. Our measured helicity basis form factors are consistent with the spectroscopic pole dominance predictions for the three main helicity basis form factors describing D^+ into anti-K*0 ell^+ nu_mu decay. The ability to analyze D^+ into K^- pi^+ mu^+ nu_mu allows us to make the first non-parametric measurements of the mass-suppressed form factor. Our result is inconsistent with existing Lattice QCD calculations. Finally, we measure the form factor that controls non-resonant s-wave interference with the D^+ into anti-K*0 ell^+ nu_mu amplitude and search for evidence of possible additional non-resonant d-wave or f-wave interference with the anti-K*0.

Large forward-backward asymmetry in B{yields}K{mu}{sup +}{mu}{sup -} from new physics tensor operators  

SciTech Connect (OSTI)

We study the constraints on possible new physics contributions to the forward-backward asymmetry of muons, A{sub FB}(q{sup 2}), in B{yields}K{mu}{sup +}{mu}{sup -}. New physics in the form of vector/axial-vector operators does not contribute to A{sub FB}(q{sup 2}), whereas new physics in the form of scalar/pseudoscalar operators can enhance A{sub FB}(q{sup 2}) only by a few percent. However, new physics in the form of tensor operators can take the peak value of A{sub FB}(q{sup 2}) to as high as 40% near the high-q{sup 2} end point. In addition, if both scalar/pseudoscalar and tensor operators are present, then A{sub FB}(q{sup 2}) can be more than 15% for the entire high-q{sup 2} region q{sup 2}>15 GeV{sup 2}. The observation of significant A{sub FB} would imply the presence of new physics tensor operators, whereas its q{sup 2} dependence could further indicate the presence of new scalar/pseudoscalar physics.

Entropy Production at High Energy and mu_B  

E-Print Network [OSTI]

The systematics of bulk entropy production in experimental data on A+A, p+p and e+e- interactions at high energies and large mu_B is discussed. It is proposed that scenarios with very early thermalization, such as Landau's hydrodynamical model, capture several essential features of the experimental results. It is also pointed out that the dynamics of systems which reach the hydrodynamic regime give similar multiplicities and angular distributions as those calculated in weak-coupling approximations (e.g. pQCD) over a wide range of beam energies. Finally, it is shown that the dynamics of baryon stopping are relevant to the physics of total entropy production, explaining why A+A and e+e- multiplicities are different at low beam energies.

Search for heavy Majorana neutrinos in $\\mu^\\pm \\mu^\\pm$+jets events in proton-proton collisions at $\\sqrt{s}$ = 8 TeV  

E-Print Network [OSTI]

A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets ($\\mu^\\pm \\mu^\\pm \\mathrm{j j}$). The data correspond to an integrated luminosity of 19.7 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. No excess of events is observed beyond the expected standard model background and upper limits are set on $|V_{\\mu\\mathrm{N}}|^2$ as a function of Majorana neutrino mass $\\mathrm{m}_{\\mathrm{N}}$ for masses in the range of 40-500 GeV, where $|V_{\\mu\\mathrm{N}}|$ is the mixing element of the heavy neutrino with the standard model muon neutrino. The limits obtained are $|V_{\\mu\\mathrm{N}}|^2 \\le 0.00470$ for $\\mathrm{m}_{\\mathrm{N}} = 90$ GeV, $|V_{\\mu\\mathrm{N}}|^2 \\le 0.0123$ for $\\mathrm{m}_{\\mathrm{N}} = 200$ GeV, and $|V_{\\mu\\mathrm{N}}|^2 \\le 0.583$ for $\\mathrm{m}_{\\mathrm{N}} = 500$ GeV.

An update for the MuCool test area  

SciTech Connect (OSTI)

Construction of a new facility known as the MuCool Test Area (MTA) has been completed at Fermi National Accelerator Laboratory. This facility supports research in new accelerator technologies for future endeavors such as a Neutrino Factory or Muon Collider. During the summer of 2004, an initial set of tests was completed for the filling of a convection-style liquid hydrogen absorber designed by KEK. The absorber contained 6.2 liquid liters of hydrogen and was tested for a range of heating conditions to quantify the absorber's heat exchanger performance. Future work at Fermilab includes the design, construction, and installation of a forced-flow absorber to be used with other components built to investigate the properties of a muon ionization cooling channel. A Tevatron-style refrigerator/compressor building is to be operational by spring of 2006 in support of the absorber tests and also to provide 5-K helium and liquid nitrogen to a 5-T solenoid magnet, an active element of the future test apparatus. The refrigerator will be configured in such a manner as to meet the 5 K and 14-20-K helium needs of the MTA. This paper reviews the challenges and successes of the past KEK absorber tests as well as looks into the future cryogenic capabilities and intentions of the site.

Cryogenics for the MuCool Test Area (MTA)  

SciTech Connect (OSTI)

MuCool Test Area (MTA) is a complex of buildings at Fermi National Accelerator Laboratory, which are dedicated to operate components of a cooling cell to be used for Muon Collider and Neutrino Factory R and D. The long-term goal of this facility is to test ionization cooling principles by operating a 25-liter liquid hydrogen (LH2) absorber embedded in a 5 Tesla superconducting solenoid magnet. The MTA solenoid magnet will be used with RF cavities exposed to a high intensity beam. Cryogens used at the MTA include LHe, LN2 and LH2. The latter dictates stringent system design for hazardous locations. The cryogenic plant is a modified Tevatron refrigerator based on the Claude cycle. The implementation of an in-house refrigerator system and two 300 kilowatt screw compressors is under development. The helium refrigeration capacity is 500 W at 14 K. In addition the MTA solenoid magnet will be batch-filled with LHe every 2 days using the same cryo-plant. This paper reviews cryogenic systems used to support the Muon Collider and Neutrino Factory R and D programs and emphasizes the feasibility of handling cryogenic equipment at MTA in a safe manner.

Thermal Design of the Mu2e Detector Solenoid  

SciTech Connect (OSTI)

The reference design for a superconducting Detector Solenoid (DS) for the Mu2e experiment has been completed. The main functions of the DS are to provide a graded field in the region of the stopping target which ranges from 2 T to 1 T and a uniform precision magnetic field of 1 T in a volume large enough to house a tracker downstream of the stopping target. The inner diameter of the magnet cryostat is 1.9 m and the length is 10.9 m. The gradient section of the magnet is about 4 m long and the spectrometer section with a uniform magnetic field is about 6 m long. The inner cryostat wall supports the stopping target, tracker, calorimeter and other equipment installed in the DS. This warm bore volume is under vacuum during operation. It is sealed on one end by the muon beam stop, while it is open on the other end where it interfaces with the Transport Solenoid. The operating temperature of the magnetic coil is 4.7 K and is indirectly cooled with helium flowing in a thermosiphon cooling scheme. This paper describes the thermal design of the solenoid, including the design aspects of the thermosiphon for the coil cooling, forced flow cooling of the thermal shields with 2 phase LN2 (Liquid Nitrogen) and the transient studies of the cool down of the cold mass as well.

E-Print Network [OSTI]

A search is presented for a standard model-like Higgs boson decaying to the $\\mu^+\\mu^-$ or $\\mathrm{e^+e^-}$ final states based on proton-proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0$~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $7~\\mathrm{TeV}$ and $19.7~\\mathrm{fb}^{-1}$ at $8~\\mathrm{TeV}$ for the $\\mu^+\\mu^-$ search, and of $19.7~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $8~\\mathrm{TeV}$ for the $\\mathrm{e^+e^-}$ search. To enhance the sensitivity of the search, events are categorized by topologies according to production process and dilepton invariant mass resolution. Upper limits on the production cross section times branching fraction at the 95% confidence level are reported for Higgs boson masses in the range from 120 to 150$~\\mathrm{GeV}$. For a Higgs boson with a mass of 125$~\\mathrm{GeV}$ decaying to $\\mu^+\\mu^-$, the observed (expected) upper limit on the production rate is found to be 7.4 ($6.5^{+2.8}_{-1.9}$) t...

Proposal to search for mu- N -> e- N with a single event sensitivity below 10 -16  

SciTech Connect (OSTI)

We propose a new experiment, Mu2e, to search for charged lepton flavor violation with unprecedented sensitivity. We will measure the ratio of the coherent neutrinoless conversion in the field of a nucleus of a negatively charged muon into an electron to the muon capture process: R{sub {mu}e} = {mu}{sup -} + A(Z,N) {yields} e{sup -} + A(Z,N)/{mu}{sup -} + A(Z,N) {yields} {nu}{sub {mu}} + A(Z-1, N), with a sensitivity R{sub {mu}e} {le} 6 x 10{sup -17} at 90% CL. This is almost a four order-of-magnitude improvement over the existing limit. The observation of such a process would be unambiguous evidence of physics beyond the Standard Model. Since the discovery of the muon in 1936, physicists have attempted to answer I.I. Rabi's famous question: 'Who ordered that?' Why is there a muon? What role does it play in the larger questions of why there are three families and flavors of quarks, leptons, and neutrinos? We know quarks mix through a mechanism described by the Cabbibo-Kobayashi-Maskawa matrix, which has been studied for forty years. Neutrino mixing has been observed in the last decade, but mixing among the family of charged leptons has never been seen. The current limits are of order 10{sup -11} - 10{sup -13} so the process is rare indeed. Why is such an experiment important and timely? A major motivation for experiments at the Large Hadron Collider (LHC) is the possible observation of supersymmetric particles in the TeV mass range. Many of these supersymmetric models predict a {mu}-e conversion signal at R{sub {mu}e} {approx} 10{sup -15}. We propose to search for {mu}-e conversion at a sensitivity that exceeds this by more than an order of magnitude. The LHC may not be able to conclusively distinguish among supersymmetric models, so Mu2e will provide invaluable information should the LHC observe a signal. In the case where the LHC finds no evidence of supersymmetry, or other beyond-the-standard-model physics, Mu2e will probe for new physics at mass scales up to 10{sup 4} TeV, far beyond the reach of any planned accelerator.

6D mu (+/-) cooling using a solenoid-dipole ring cooler for a muon collider  

SciTech Connect (OSTI)

Six dimensional cooling of large emittance {mu}{sup +} and {mu}{sup -} beams is required in order to obtain the desired luminosity for a muon collider. We propose to use a ring cooler that employs both dipoles and solenoids with the additional requirement that the arcs of the ring be achromatic. We describe the lattice and the beam dynamics of the proposed ring, and demonstrate that the lattice gives substantial cooling in all 6 phase space dimensions.

On the model discriminating power of mu to e conversion in nuclei  

SciTech Connect (OSTI)

Lepton Flavor Violating (LFV) charged lepton decays provide a highly sensitive probe of physics beyond the Standard Model (SM), due to the un-observably small branching fractions ({approx}10{sup -50}) predicted for these modes in the SM (minimally extended to include massive neutrinos). Searches for SM forbidden muon processes, such as {mu} {yields} e{gamma}, {mu} {yields} e{bar e}e, and {mu} {yields} e conversion in nuclei, have provided so far the strongest constraints on LFV new physics. This statement can be characterized in a model-independent way as a lower bound on the scale associated to a set of dimension six effective operators parameterizing new physics beyond the SM. It is a well known fact that while the decay {mu} {yields} e{gamma} is only sensitive to a transition magnetic dipole operator, both {mu} {yields} e{bar e}e and {mu} {yields} e conversion in nuclei are sensitive to transition charge radii operators as well as purely contact four-fermion interactions induced by physics beyond the SM. In other words, different LFV decays have different sensitivities to underlying LFV mechanisms (effective operators). This leads naturally to ask the question whether one could infer the relative strength of these different operators in a completely phenomenological and model-independent way. This would allow one to discriminate among different underlying models of LFV and thus would provide valuable input for model building. In Ref. [1] it was pointed out that in principle, by combining the rates of {mu} {yields} e{gamma} and {mu} {yields} e conversion on different target nuclei, one could discriminate underlying models. In this work we go back to this issue with the aim to: quantify the theoretical uncertainty induced by the hadronization process; and quantify the experimental precision required to realistically infer useful information on the underlying LFV mechanisms. We organize our discussion as follows: in Section 2 we review the derivation of the {mu} {yields} e conversion rate starting from a general effective theory description of the LFV physics. In Section 3 we explore the phenomenological consequence of the simplest possible models, in which only one effective LFV operator dominates. We extend this analysis in Section 4 to the class of models in which two operators dominate. In Section 5 we specialize our discussion to the SUSY see-saw model and summarize the conclusions of our analysis in Section 6.

Nuclear 11.3$\\mu$m PAH emission in local active galactic nuclei  

E-Print Network [OSTI]

We present Gran Telescopio CANARIAS CanariCam 8.7$\\mu$m imaging and 7.5-13$\\mu$m spectroscopy of six local systems known to host an active galactic nucleus (AGN) and have nuclear star formation. Our main goal is to investigate whether the molecules responsible for the 11.3$\\mu$m polyclyclic aromatic hydrocarbon (PAH) feature are destroyed in the close vicinity of an AGN. We detect 11.3$\\mu$m PAH feature emission in the nuclear regions of the galaxies as well as extended PAH emission over a few hundred parsecs. The equivalent width (EW) of the feature shows a minimum at the nucleus but increases with increasing radial distances, reaching typical star-forming values a few hundred parsecs away from the nucleus.

NEW CONSTRAINTS ON COMPANIONS AND DUST WITHIN A FEW AU OF VEGA  

SciTech Connect (OSTI)

We report on high contrast near-infrared ({approx}2.2 {mu}m) observations of Vega obtained with the Palomar Fiber Nuller, a dual sub-aperture rotating coronagraph installed at the Palomar Hale telescope. The data show consistent astrophysical null depth measurements at the {approx_equal} 10{sup -3} level or below for three different baseline orientations spanning 60 deg in azimuth, with individual 1{sigma} uncertainties {<=}7 x 10{sup -4}. These high cancellation and accuracy levels translate into a dynamic range greater than 1000:1 inside the diffraction limit of the 5 m telescope beam. Such high contrast performance is unprecedented in the near-infrared and provides improved constraints on Vega's immediate ({approx_equal}20 to 250 mas, or {approx_equal}0.15 to 2 AU) environment. In particular, our measurements rule out any potential companion in the [0.25-1 AU] region contributing more than 1% of the overall near-infrared stellar flux, with limits as low as 0.2% near 0.6 AU. These are the best upper limits established so far by direct detection for a companion to Vega in this inner region. We also conclude that any dust population contributing a significant ({>=}1%) near-infrared thermal excess can arise only within 0.2 AU of the star, and that it must consist of much smaller grains than in the solar zodiacal cloud. Dust emission from farther than {approx_equal}2 AU is also not ruled out by our observations, but would have to originate in strong scattering, pointing again to very small grains.

Global polarization measurement in Au+Au collisions  

SciTech Connect (OSTI)

The system created in non-central relativisticnucleus-nucleus collisions possesses large orbital angular momentum. Dueto spin-orbit coupling, particles produced in such a system could becomeglobally polarized along the direction of the system angular momentum. Wepresent the results of Lambda and anti-Lambda hyperon global polarizationmeasurements in Au+Au collisions at sqrt sNN=62.4 GeV and 200 GeVperformed with the STAR detector at RHIC. The observed globalpolarization of Lambda and anti-Lambda hyperons in the STAR acceptance isconsistent with zero within the precision of the measurements. Theobtained upper limit, lbar P Lambda, anti-Lambda rbar<= 0.02, iscompared to the theoretical values discussed recently in theliterature.

Correlations of trace elements in breast human tissues: Evaluation of spatial distribution using {mu}-XRF  

SciTech Connect (OSTI)

The aim of this work is to investigate microscopic correlations between trace elements in breast human tissues. A synchrotron X-ray fluorescence microprobe system ({mu}-XRF) was used to obtain two-dimensional distribution of trace element Ca, Fe, Cu and Zn in normal (6 samples) and malignant (14 samples) breast tissues. The experiment was performed in X-ray Fluorescence beam line at Laboratorio Nacional de Luz Sincrotron (LNLS), Campinas, Brazil. The white microbeam was generated with a fine conical capillary with a 20 {mu}m output diameter. The samples were supported on a XYZ table. An optical microscope with motorized zoom was used for sample positioning and choice the area to be scanned. Automatic two-dimensional scans were programmed and performed with steps of 30 {mu}m in each direction (x, y) on the selected area. The fluorescence signals were recorded using a Si(Li) detector, positioned at 90 degrees with respect to the incident beam, with a collection time of 10 s per point. The elemental maps obtained from each sample were overlap to observe correlation between trace elements. Qualitative results showed that the pairs of elements Ca-Zn and Fe-Cu could to be correlated in malignant breast tissues. Quantitative results, achieved by Spearman correlation tests, indicate that there is a spatial correlation between these pairs of elements (p < 0.001) suggesting the importance of these elements in metabolic processes associated with the development of the tumor.

Periodic density functional theory calculations were used to investigate relevant aspects of adsorption mechanisms of cysteine dimers in protonated form on Au(111) and Au(110) surfaces. The projected densities of states are explicitly discussed for all main chemical groups of cysteine, i.e. the amino group (NH2), the thiol group (SH) and the carboxylic group (COOH) to identify differences in adsorption mechanism. Special emphasis is put on the analysis of changes in the electronic structure of molecules adsorbed on Au(111) and Au(110) surfaces as well as the accompanying charge transfer mechanisms at molecule-substrate interaction.

Systematic Measurements of Identified Particle Spectra in pp, d+Au and Au+Au Collisions from STAR  

SciTech Connect (OSTI)

Identified charged particle spectra of {pi}{sup {+-}}, K{sup {+-}}, p and {bar p} at mid-rapidity (|y| < 0.1) measured by the dE/dx method in the STAR-TPC are reported for pp and d + Au collisions at {radical}s{sub NN} = 200 GeV and for Au + Au collisions at 62.4 GeV, 130 GeV, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm{sub 3} for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au + Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au + Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters due to the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close to the predicted phase-transition temperature, suggesting that chemical freeze-out happens in the vicinity of hadronization and the chemical freezeout temperature is universal despite the vastly different initial conditions in the collision systems. The extracted kinetic freeze-out temperature, while similar to the chemical freeze-out temperature in pp, d + Au, and peripheral Au + Au collisions, drops significantly with centrality in Au + Au collisions, whereas the extracted transverse radial flow velocity increases rapidly with centrality. There appears to be a prolonged period of particle elastic scatterings from chemical to kinetic freeze-out in central Au + Au collisions. The bulk properties extracted at chemical and kinetic freeze-out are observed to evolve smoothly over the measured energy range, collision systems, and collision centralities.

Airbreathing Laser Propulsion Experiments with 1 {mu}m Terawatt Pharos IIILaser: Part 2  

SciTech Connect (OSTI)

This basic research study examines the physics of airbreathing laser propulsion at the extreme flux range of 1-2x10{sup 11} W/cm{sup 2}--within the air breakdown threshold for l {mu}m radiation--using the terawatt Pharos III neodymium-glass pulsed laser. Six different experimental setups were employed using a 34 mm line focus with 66 {mu}m focal waist, positioned near the flat impulse surface. The 2nd Campaign investigated impulse generation with the laser beam focused at grazing incidence across near horizontal target surfaces, with pulse energies ranging from 55 to 186 J, and pulse-widths of 2 to 30 ns FWHM. Laser generated impulse was measured with a horizontal Plexiglas registered ballistic pendulum equipped with either a steel target insert or 0.5 Tesla permanent magnet (NEIT-40), to quantify changes in the momentum coupling coefficient (C{sub M}). Part 2 of this 2-part paper covers Campaign no. 2 results including C{sub M} performance data, and long exposure color photos of LP plasma phenomena.

Broadband carbon monoxide laser system operating in the wavelength range of 2.5 - 8.3 {mu}m  

SciTech Connect (OSTI)

A two-cascade frequency conversion of CO-laser radiation is demonstrated in a single sample of a nonlinear ZnGeP{sub 2} crystal. The crystal is pumped by a repetitively pulsed cryogenic lowpressure CO laser operating on {approx}150 vibration - rotational transitions in the wavelength range 5.0 - 7.5 {mu}m, which corresponds to the frequency range of a half octave. In the first conversion cascade, generation of second harmonic and sum frequencies of various pairs of CO-laser radiation give {approx}350 emission lines in the wavelength range 2.5 - 3.7 {mu}m. In the second cascade, by mixing the radiation converted in the first cascade with the residual radiation of the CO laser we have obtained {approx}90 lines in the range 4.3 - 5.0 {mu}m and more than 80 lines in the range 7.5 - 8.3 {mu}m. Thus, using a single sample of the nonlinear ZnGeP{sub 2} crystal pumped by the radiation of a single CO laser we have produced a source of broadband (more than one and a half octaves) laser radiation, simultaneously operating at {approx}670 lines in the wavelength range 2.5 - 8.3 {mu}m.

An annular Si drift detector mu PIXE system using AXSIA analysis.  

SciTech Connect (OSTI)

Sandia and Rontec have developed an annular, 12-element, 60 mm{sup 2}, Peltier-cooled, translatable, silicon drift detector called the SDD-12. The body of the SDD-12 is only 22.8 mm in total thickness and easily fits between the sample and the upstream wall of the Sandia microbeam chamber. At a working distance of 1 mm, the solid angle is 1.09 sr. The energy resolution is 170 eV at count rates <40 kcps and 200 eV for rates of 1 Mcps. X-ray count rates must be maintained below 50 kcps when protons are allowed to strike the full area of the SDD. Another innovation with this new {mu}PIXE system is that the data are analyzed using Sandia's Automated eXpert Spectral Image Analysis (AXSIA).

Identified particle distributions in pp and Au+Au collisions atsqrt sNN=200 GeV  

SciTech Connect (OSTI)

Transverse mass and rapidity distributions for charged pions, charged kaons, protons and antiprotons are reported for {radical}sNN = 200 GeV pp and Au+Au collisions at RHIC. The transverse mass distributions are rapidity independent within |y| < 0.5, consistent with a boost-invariant system in this rapidity interval. Spectral shapes and relative particle yields are similar in pp and peripheral Au+Au collisions and change smoothly to central Au+Au collisions. No centrality dependence was observed in the kaon and antiproton production rates relative to the pion production rate from medium-central to central collisions. Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and relatively long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.

Local Thermalization in the d + Au System  

E-Print Network [OSTI]

The extent of a locally equilibrated parton plasma in d + Au collisions at sqrt(s_NN) = 200 GeV is investigated as a function of collision centrality in a nonequilibrium-statistical framework. Based on a three-sources model, analytical solutions of a relativistic diffusion equation are in precise agreement with recent data for charged-particle pseudorapidity distributions. The moving midrapidity source indicates the size of the local thermal equilibrium region after hadronization. In central d + Au collisions it contains about 19% of the produced particles, and its relative importance rises with decreasing centrality.

Optical losses of Al-free lasers for {lambda}=0.808 and 0.98 {mu}m  

SciTech Connect (OSTI)

In this work, we study the origin of the optical losses in Al-free InGaAsP/GaAs ({lambda}=0.808 {mu}m) and InGaAs/GaAs/InGaP ({lambda}=0.980 {mu}m) lasers. Theoretical modeling and the experimental results indicate that the scattering of the laser beam by refractive index fluctuation in the alloys is the dominant loss in our lasers, and the loss due to the free-carrier absorption and scattering by interface roughness are negligible. {copyright} {ital 1996 American Institute of Physics.}

Technique for Direct eV-Scale Measurements of the Mu and Tau Neutrino Masses Using Supernova Neutrinos  

E-Print Network [OSTI]

Early black hole formation in a core-collapse supernova will abruptly truncate the neutrino fluxes. The sharp cutoff can be used to make model-independent time-of-flight neutrino mass tests. Assuming a neutrino luminosity of $10^{52}$ erg/s per flavor at cutoff and a distance of 10 kpc, SuperKamiokande can detect an electron neutrino mass as small as 1.8 eV, and the proposed OMNIS detector can detect mu and tau neutrino masses as small as 6 eV. This {\\it Letter} presents the first technique with direct sensitivity to eV-scale mu and tau neutrino masses.

Surface effects on the radiation response of nanoporous Au foams  

SciTech Connect (OSTI)

We report on an experimental and simulation campaign aimed at exploring the radiation response of nanoporous Au (np-Au) foams. We find different defect accumulation behavior by varying radiation dose-rate in ion-irradiated np-Au foams. Stacking fault tetrahedra are formed when np-Au foams are irradiated at high dose-rate, but they do not seem to be formed in np-Au at low dose-rate irradiation. A model is proposed to explain the dose-rate dependent defect accumulation based on these results.

A search for. nu. sub e appearance from stopped. pi. sup + and. mu. sup + decay at LAMPF (Los Alamos Meson Physics Facility)  

SciTech Connect (OSTI)

We report on a recent search for {bar {nu}}{sub e} appearance from stopped {pi}{sup +} {yields} {mu}{sup +}{nu}{sub {mu}} and {mu}{sup +} {yields} e{sup +}{nu}{sub e}{bar {nu}}{sub {mu}} decay made by the LAMPF experiment E645. The appearance of {bar {nu}}{sub e} may occur from {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e}, {nu}{sub e} {yields} {bar {nu}}{sub eL}, or {nu}{sub {mu}} {yields} {bar {nu}}{sub eL} oscillations. Appearance may also occur from rare {mu}{sup +} {yields} e{sup +}{bar {nu}}{sub e}{nu}{sub {mu}} decay, which is allowed by a multiplicative lepton charge conservation law. The neutrino energies range from E{sub {nu}} = 0 to 52.8MeV. The neutrino detector, which is located 26.1 meters from the neutrino source, consists of a segmented liquid scintillator and proportional drift tube central detector surrounded by both active and passive shielding. The central detector detects {bar {nu}}{sub e} through the {bar {nu}}{sub e}p {yields} ne{sup +} Charge Current (CC) reaction, which is signaled by the direct detection of the final state positron and neutron. The hydrogen-rich liquid scintillators act as free proton targets for the {bar {nu}}{sub e}p CC reaction. The neutrons are detected through radiative neutron capture on gadolinium. We find no evidence for {bar {nu}}{sub e} appearance in the first year of running. New limits on the {bar {nu}}{sub {mu}},{nu}{sub e},{nu}{sub {mu}} {yields} {bar {nu}}{sub e} oscillation parameters and the rare {mu}{sup +} {yields} e{sup +}{bar {nu}}{sub e}{nu}{sub {mu}} decay branching ratio are presented. 87 refs., 45 figs., 17 tabs.

Revisiting the relationship between 6 {\\mu}m and 2-10 keV continuum luminosities of AGN  

E-Print Network [OSTI]

We have determined the relation between the AGN luminosities at rest-frame 6 {\\mu}m associated to the dusty torus emission and at 2-10 keV energies using a complete, X-ray flux limited sample of 232 AGN drawn from the Bright Ultra-hard XMM-Newton Survey. The objects have X-ray luminosities corrected for intrinsic absorption between 10^42 and 10^46 erg/s and redshifts from 0.05 to 2.8. The rest-frame 6 {\\mu}m luminosities were computed using data from the Wide-Field Infrared Survey Explorer and are based on a spectral energy distribution decomposition into AGN and galaxy emission. The best-fit relationship for the full sample is consistent with being linear, L_6 {\\mu}m $\\propto$ L_2-10 keV^0.99$\\pm$0.032, but has significant intrinsic scatter, ~0.35 dex in log L_6 {\\mu}m. Assuming a constant X-ray bolometric correction, the fraction of AGN bolometric luminosity reprocessed in the mid-IR decreases weakly, if at all, with the AGN luminosity, a finding at odds with simple receding torus models.

SPITZER 24 {mu}m EXCESSES FOR BRIGHT GALACTIC STARS IN BOOeTES AND FIRST LOOK SURVEY FIELDS  

SciTech Connect (OSTI)

Optically bright Galactic stars (V {approx}< 13 mag) having f {sub {nu}}(24 {mu}m) > 1 mJy are identified in Spitzer mid-infrared surveys within 8.2 deg{sup 2} for the Booetes field of the NOAO Deep Wide-Field Survey and within 5.5 deg{sup 2} for the First Look Survey (FLS). One hundred and twenty-eight stars are identified in Booetes and 140 in the FLS, and their photometry is given. (K - [24]) colors are determined using K magnitudes from the Two Micron All Sky Survey for all stars in order to search for excess 24 {mu}m luminosity compared to that arising from the stellar photosphere. Of the combined sample of 268 stars, 141 are of spectral types F, G, or K, and 17 of these 141 stars have 24 {mu}m excesses with (K - [24]) > 0.2 mag. Using limits on absolute magnitude derived from proper motions, at least eight of the FGK stars with excesses are main-sequence stars, and estimates derived from the distribution of apparent magnitudes indicate that all 17 are main-sequence stars. These estimates lead to the conclusion that between 9% and 17% of the main-sequence FGK field stars in these samples have 24 {mu}m infrared excesses. This result is statistically similar to the fraction of stars with debris disks found among previous Spitzer targeted observations of much brighter, main-sequence field stars.

INFRARED LUMINOSITIES AND AROMATIC FEATURES IN THE 24 {mu}m FLUX-LIMITED SAMPLE OF 5MUSES  

SciTech Connect (OSTI)

We study a 24 {mu}m selected sample of 330 galaxies observed with the infrared spectrograph for the 5 mJy Unbiased Spitzer Extragalactic Survey. We estimate accurate total infrared luminosities by combining mid-IR spectroscopy and mid-to-far infrared photometry, and by utilizing new empirical spectral templates from Spitzer data. The infrared luminosities of this sample range mostly from 10{sup 9} L{sub sun} to 10{sup 13.5} L{sub sun}, with 83% in the range 10{sup 10} L{sub sun} < L{sub IR} < 10{sup 12} L{sub sun}. The redshifts range from 0.008 to 4.27, with a median of 0.144. The equivalent widths of the 6.2 {mu}m aromatic feature have a bimodal distribution, probably related to selection effects. We use the 6.2 {mu}m polycyclic aromatic hydrocarbon equivalent width (PAH EW) to classify our objects as starburst (SB)-dominated (44%), SB-AGN composite (22%), and active galactic nucleus (AGN)-dominated (34%). The high EW objects (SB-dominated) tend to have steeper mid-IR to far-IR spectral slopes and lower L{sub IR} and redshifts. The low EW objects (AGN-dominated) tend to have less steep spectral slopes and higher L{sub IR} and redshifts. This dichotomy leads to a gross correlation between EW and slope, which does not hold within either group. AGN-dominated sources tend to have lower log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios than star-forming galaxies, possibly due to preferential destruction of the smaller aromatics by the AGN. The log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios for star-forming galaxies are lower in our sample than the ratios measured from the nuclear spectra of nearby normal galaxies, most probably indicating a difference in the ionization state or grain size distribution between the nuclear regions and the entire galaxy. Finally, we provide a calibration relating the monochromatic continuum or aromatic feature luminosity to L{sub IR} for different types of objects.

Planetary companions in K giants beta Cancri, mu Leonis, and beta Ursae Minoris  

E-Print Network [OSTI]

Auns. The aim of our paper is to investigate the low-amplitude and long-period variations in evolved stars with a precise radial velocity (RV) survey. Methods. The high-resolution, the fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) was used from 2003 to 2013 for a radial velocity survey of giant stars as part of the exoplanet search program at Bohyunsan Optical Astronomy Observatory (BOAO). Results. We report the detection of three new planetary companions orbiting the K giants beta Cnc, mu Leo, and beta UMi. The planetary nature of the radial velocity variations is supported by analyzes of ancillary data. The HIPPARCOS photometry shows no variations with periods close to those in RV variations and there is no strong correlation between the bisector velocity span (BVS) and the radial velocities for each star. Furthermore, the stars show weak or no core reversal in Ca II H lines indicating that they are inactive stars. The companion to beta Cnc has a minimum mass of 7.8 M_Jup in a 605-day orbit wi...

Optimization of Extinction Efficiency in the 8-GeV Mu2e Beam Line  

SciTech Connect (OSTI)

A muon-to-electron conversion experiment at Fermilab, Mu2e, is being designed to probe for new physics beyond the standard model at mass scales up to 10{sup 4} TeV. For this experiment, the advance in experimental sensitivity will be four orders of magnitude when compared to existing data on charged lepton flavor violation. The muon beam will be produced by delivering a proton beam contained in short 100-ns bunches onto a muon production target, with an inter-bunch separation of about 1700 ns. A critical requirement of the experiment is to ensure a low level of background at the muon detector consistent with the required sensitivity. To meet the sensitivity requirement, protons that reach the target between bunches must be suppressed by an enormous factor, so that an extinction factor, defined as a number of background protons between main bunches per proton in such a bunch, should not exceed 10{sup -9}. This paper describes the advanced beam optics and results of numerical modeling with STRUCT and MARS codes for a beam line with a collimation system that allows us to achieve the experimental extinction factor of one per billion.

Effect of active layer thickness on differential quantum efficiency of 1. 3 and 1. 55. mu. m InGaAsP injection lasers  

SciTech Connect (OSTI)

The dependence of differential quantum efficiency (eta/sub d/) on active layer thickness (d) for 1.3 and 1.55 ..mu..m InGaAsP buried crescent (BC) injection lasers has been measured. A comparison of the results shows that eta/sub d/ for 1.55 ..mu..m lasers increases more rapidly with decreasing d than eta/sub d/ for 1.3 ..mu..m lasers. The significantly different dependence of eta/sub d/ on d in BC lasers suggests that the optical absorption in the active region of InGaAsP lasers is strongly wavelength dependent. This gives the important practical conclusion that the eta/sub d/ for 1.55 ..mu..m lasers can be significantly improved by reducing d, whereas the eta/sub d/ for 1.3 ..mu..m lasers can only be slightly improved by reducing d. As a result of eta/sub d/ vs d investigation, we have obtained high performance 1.3 and 1.55 ..mu..m BC lasers which exhibit threshold currents as low as 9 mA at 25 /sup 0/C, high-temperature operation (up to 100 /sup 0/C), and eta/sub d/ over 65% (1.3 ..mu..m) and 45% (1.55 ..mu..m).

Water in Emission in the ISO Spectrum of the Early M Supergiant Star mu Cephei  

E-Print Network [OSTI]

We report a detection of water in emission in the spectrum of the M2 supergiant atar mu Cep (M2Ia) observed by the Short Wavelength Spectrometer (SWS) aboard Infrared Space Observatory (ISO) and now released as the ISO Archives. The emission first appears in the 6 micron region (nu2 fundamental) and then in the 40 micron region (pure rotation lines) despite the rather strong dust emission. The intensity ratios of the emission features are far from those of the optically thin gaseous emission. Instead, we could reproduce the major observed emission features by an optically thick water sphere of the inner radius about two stellar radii (1300Rsun), Tex = 1500K, and Ncol (H2O) = 3.0E+20/cm2. This model also accounts for the H2O absorption bands in the near infrared (1.4, 1.9, and 2.7 micron) as well. The detection of water in emission provides strong constraints on the nature of water in the early M supergiant stars, and especially its origin in the outer atmosphere is confirmed against other models such as the large convective cell model. We finally confirm that the early M supergiant star is surrounded by a huge optically thick sphere of the warm water vapor, which may be referred to as MOLsphere for simplicity. Thus, the outer atmosphere of M supergiant stars should have a complicated hierarchical and/or hybrid structure with at least three major constituents including the warm MOLsphere (T about 1.0E+3K) together with the previously known hot chromosphere (T about 1.0E+4K) and cool expanding gas-dust envelope (T about 1.0E+2K).

Performance of Mo/Au TES microcalorimeters  

Science Journals Connector (OSTI)

We are developing X-ray calorimeters to meet the specifications of the Constellation-X mission. Each calorimeter consists of a transition-edge-sensor (TES) thermometer which is suspended on a silicon-nitride membrane. Our TES thermometers are Mo/Au bilayer films that are biased in the sharp phase transition between the superconducting and normal-metal states. These calorimeters have demonstrated very good energy resolutions: 2.4 eV at 1.5 keV and 3.7 eV at 3.3 keV. The energy resolutions are limited by thermal noise and Johnson noise (which are intrinsic to any resistive calorimeter) plus excess noise. The excess noise which is several times larger than the Johnson noise is consistent with frequency-independent voltage noise in the TES. Detailed measurements of one Mo/Au TES demonstrate that the excess noise is independent of the voltage applied to the TES over a range of biases at the same TES resistance. The magnitude of the excess noise is smallest at the high-resistance end of the phase transition. We also compared noise in square Mo/Au TES’s ranging in size from 300 microns to 600 microns to learn how the excess noise is affected by the geometry of the TES.

Evaluation of the Au Size Effect: CO Oxidation Catalyzed by Au/TiO2  

SciTech Connect (OSTI)

The size dependence of activity in gold catalysts was examined. Extended X-ray absorption fine structure was used to determine mean particle size, and a flow reactor was used to assess activity of the catalysts for CO oxidation as a function of temperature. A sequence of calcination steps was used to systematically increase the mean Au particle size while repeated measurements of the activity were conducted. In this way the size dependence could be obtained in a single catalyst to avoid differences due to variations in support, synthesis conditions, Au loading, or incidental impurities. Two Au catalysts with different Au loadings were prepared on TiO{sub 2} by deposition precipitation and used for the measurements. For Au particles with mean particle size, d, in the range of 2-10 nm, the measured TOF at 298 K varies as d{sup -1.7{+-}0.2} and d{sup -0.9{+-}0.2} for the 7.2 and 4.5 wt% Au/TiO{sub 2} (P25) catalysts, respectively. Variation between samples emphasizes the conclusion that the activity is sensitive to many factors that may mask the true structure dependence. It is concluded that the observed decrease in activity with increasing particle size beyond 2 nm is controlled by the population of low-coordinate sites, rather than by size-dependent changes in overall electronic structure of the nanoparticle. No evidence was found for maximum activity for small particle sizes, although arguments are offered for why such a maximum was expected but was not observed.

Collective motion in selected central collisions of Au on Au at 150A MeV  

Science Journals Connector (OSTI)

Using the FOPI facility at GSI Darmstadt complete data of Au on Au collisions at 150A MeV were collected for charged products (Z=1–15) at laboratory angles 1°??lab?30°. Central collisions were selected by applying various criteria. The kinetic energy spectra of fragments from an isolated midrapidity source are investigated in detail for center-of-mass angles 25°??c.m.?45°. The heavy products (Z?3) are used to determine the collective energy which is found to be at least 10A MeV.

Charged Particle Multiplicities in Ultra-relativistic Au+Au and Cu+Cu Collisions  

E-Print Network [OSTI]

The PHOBOS collaboration has carried out a systematic study of charged particle multiplicities in Cu+Cu and Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory. A unique feature of the PHOBOS detector is its ability to measure charged particles over a very wide angular range from 0.5 to 179.5 deg. corresponding to |eta|<5.4. The general features of the charged particle multiplicity distributions as a function of pseudo-rapidity, collision energy and centrality, as well as system size, are discussed.

Light Fragment Production and Power Law Behavior in Au + Au Collisions  

Science Journals Connector (OSTI)

Using charged-particle-exclusive measurements of Au+Au collisions in the LBL Bevalac's EOS time projection chamber, we investigate momentum-space densities of fragments up to 4He as a function of fragment transverse momentum, azimuth relative to the reaction plane, rapidity, multiplicity, and beam energy. Most features of these densities above a transverse momentum threshold are consistent with momentum-space coalescence, and, in particular, the increase in sideward flow with fragment mass is generally well described by a momentum-space power law.

Measurements of forbidden line radiation of Ar II (6. 99. mu. m) in W3 IRS 1  

SciTech Connect (OSTI)

Observations of the (Ar II) (6.99 ..mu..m) line flux in W3 IRS 1 are combined with previously obtained measurements of the (Ar III) (8.99 ..mu..m) line flux. The observed ratio of (Ar II)/(Ar III) is inconsistent with the calculated ratio for an H II region with the densities required by radio observations and with a central 40,000--45,000 K star with atmosphere as described by a Mihalas model. A solar effective UV radiation field is required; a dusty model we had previously invoked fits the observations. In addition we determine that the argon abundance is n(Ar)/n(H)roughly-equal8 x 10/sup -6/, a value about twice that usually adopted for normal solar abundance; however, there are uncertainties in the extinction and the model which do not allow us to preclude solar abundance.

Positive-tone silylated, dry-developed, deep ultraviolet resist with 0. 2 [mu]m resolution  

SciTech Connect (OSTI)

This paper describes the development of a surface-imaging process for a positive-tone silylated, dry-developed bilayer resist which has 0.2 [mu]m resolution and an aspect ratio of 4.5 using deep-UV (248 nm) exposure. The many processing variables such as thermal treatment parameters, silylation conditions, and etching conditions were examined to determine their effects on lithographic performance in terms of resolution, feature size linearity, focus latitude, and sensitivity. Critical to the success of the process are: the bilayer structure which restricts diffusion of the Si, the use of a disilane reagent to increase the Si content of the masking layer, limiting migration of photogenerated acid by the appropriate choice of softbake and post-exposure bake temperatures, initial etching with an Ar/Cl[sub 2] mixture to remove the thin layer of silylated resist in the exposed areas, and employing CO[sub 2] instead of O[sub 2] as the etching gas to eliminate lateral etching of the features. With this process we have obtained good critical dimension linearity down to 0.25 [mu]m for bright-field and dark-field lines and spaces as well as isolated lines and isolated spaces. The dose required is [similar to]75 mJ/cm[sup 2] and the dose latitude is [plus minus]6%. Focus latitude is at least [plus minus]0.4 [mu]m. We also observe no environmental effects on sensitivity or resolution.

Full jet reconstruction in 200 GeV p+p, d+Au and Au+Au collisions by STAR  

E-Print Network [OSTI]

Measurements of inclusive hadron suppression and di-hadron azimuthal correlations have provided important insights into jet quenching in hot QCD matter. However, they do not provide access to the energy of the hard scattering and are limited in their sensitivity since they can be affected by biases toward hard fragmentation and small energy loss. Full jet reconstruction in heavy-ion collisions enables a complete study of the modification of jet structure due to energy loss, but is challenging due to the high multiplicity environment. Study of jet production and properties in d+Au and p+p collisions provides important baseline measurement for jet studies in heavy-ion collisions. We report measurements of fully reconstructed jets in p+p, d+Au and Au+Au collisions at $\\sqrt{s_\\mathrm{NN}} = 200 \\mathrm{GeV}$ from the STAR experiment at RHIC. Measurement of initial state nuclear effects in d+Au collisions utilizing di-jet azimuthal correlations is presented together with similar measurement in p+p collisions. Inclusive jet $\\pt$ spectra and fragmentation functions in p+p and central Au+Au collisions are reported, with subsequent studies of jet nuclear modification factor, jet energy profile and modifications in the fragmentation function due to jet quenching.

{phi} meson production in Au + Au and p + p collisions at {radical}s{sub NN}=200 GeV  

SciTech Connect (OSTI)

We report the STAR measurement of {psi} meson production in Au + Au and p + p collisions at {radical}s{sub NN} = 200 GeV. Using the event mixing technique, the {psi} spectra and yields are obtained at midrapidity for five centrality bins in Au+Au collisions and for non-singly-diffractive p+p collisions. It is found that the {psi} transverse momentum distributions from Au+Au collisions are better fitted with a single-exponential while the p+p spectrum is better described by a double-exponential distribution. The measured nuclear modification factors indicate that {psi} production in central Au+Au collisions is suppressed relative to peripheral collisions when scaled by the number of binary collisions (). The systematics of versus centrality and the constant {psi}/K{sup -} ratio versus beam species, centrality, and collision energy rule out kaon coalescence as the dominant mechanism for {psi} production.

Absorption, emission, and gain spectra of 1. 3. mu. m InGaAsP quaternary lasers

The spontaneous emission spectrum of mesa lasers was analyzed to determine the absorption and gain spectra at threshold. The radiative current density at threshold was found to be 4.4 kA cm/sup -2/ ..mu..m/sup -1/, which is 60 percent of the total current density for the lowest threshold mesa laser. The increase in radiative lifetime due to reabsorption of emitted radiation was calculated to be 1.5, using the measured absorption and emission spectra. Contrary to other studies, this investigation of an LED and 3 lasers of different types yielded no evidence of carrier heating.

To obtain a high output power on the 251-..mu..m line of a CH/sub 3/OH laser, four types of far-infrared output mirror are examined. It is found that the capacitive aluminium-mesh mirror of the Danielewicz type, which is fabricated by conventional vacuum deposition techniques in the present work, selectively extracts an output power of 18 mW from a 25-W pump. Also, exact assignment of the line is achieved by tuning the far-infrared cavity using the mirror.

One- and two-nucleon transfer reactions to Au196  

Science Journals Connector (OSTI)

To provide information for comparison with predictions from a dynamical supersymmetry, the odd-odd nucleus Au196 was studied via transfer reactions. With a polarized deuteron beam we measured (d?,t) and (d?,?), and with unpolarized beams we measured (p,d), (He3,d), and (?,d) transfer reactions. From the high-resolution Au197(p,d)Au196 spectrum, a rather complete set of excitation energies was obtained. Quantum numbers and spectroscopic factors were obtained from angular distributions of single-neutron transfer in Au197(d?,t)Au196, single-proton transfer in Pt195(He3,d)Au196, and two-nucleon transfer Hg198(d?,?)Au196. We obtain firm J? assignments for 21 out of the 27 states with negative parity observed up to 490keV excitation energy, by combining our data with that taken using ?? and conversion electron spectroscopy. The number of states and the firm or restricted assignments are in agreement with the predictions from the dynamical U?(6?12)?U?(6?4) supersymmetric scheme. Including our (?,d) data, we can deduce spectroscopic factors for four different transfer channels. When model predictions of spectroscopic factors become available, these data will provide a further critical test as to what extent this symmetry is realized in nature.

Entropy in central Au+Au reactions between 100 and 400A MeV  

Science Journals Connector (OSTI)

The ratio of the total charge bound in fragments with Z between 2 and 15 to the hydrogen yield, (tsum215MiZi)/MH, has been measured, and the neutron-to-proton ratio n/p has been estimated from the data of central Au + Au reactions between 100 and 400A MeV, measured with the phase I setup of the detector system FOPI and GSI, Darmstadt, in the polar-angle range between 7° and 30°. These two quantities were used to determine the entropy per nucleon S/A by comparing them with the predictions of the freesco code. The analysis allows the simulataneous extraction of the values of the baryonic entropy, temperature, and collective flow. The extracted values are in good agreement with the values obtained in earlier FOPI studies, and, for the baryonic entropy, with recent hydrodynamic calculations.

Neutral pion production in Au+Au collisions at sNN=200 GeV  

Science Journals Connector (OSTI)

The results of midrapidity (0conversion electron-positron pairs. Our measurements are compared to previously published ?± and ?0 results. The nuclear modification factors RCP and RAA of ?0 are also presented as a function of pT. In the most central Au+Au collisions, the binary collision scaled ?0 yield at high pT is suppressed by a factor of about 5 compared to the expectation from the yield of p+p collisions. Such a large suppression is in agreement with previous observations for light quark mesons and is consistent with the scenario that partons suffer considerable energy loss in the dense medium formed in central nucleus-nucleus collisions at the Relativistic Heavy Ion Collider.

Elliptic flow: transition from out-of-plane to in-plane emissionin Au + Au collisions  

SciTech Connect (OSTI)

We have measured the proton elliptic flow excitation function for the Au+Au system spanning the beam energy range (2-8)A GeV. The excitation function shows a transition from negative to positive elliptic flow at a beam energy, Etr {approx} 4A GeV. Detailed comparisons with calculations from a relativistic Boltzmann equation are presented. The comparisons suggest a softening of the nuclear equation of state from a stiff form (K {approx} 380 MeV) at low beam energies (Ebeam < 2A GeV) to a softer form (K {approx} 210 MeV) at higher energies ( Ebeam < 4A GeV) where the calculated baryon density rho {approx} 4 rho 0.

Study of quasielastic scattering using charged-current nu_mu-iron interactions in the MINOS Near Detector  

E-Print Network [OSTI]

Kinematic distributions from an inclusive sample of 1.41 x 10^6 charged-current nu_mu interactions on iron, obtained using the MINOS Near Detector exposed to a wide-band beam with peak flux at 3 GeV, are compared to a conventional treatment of neutrino scattering within a Fermi gas nucleus. Results are used to guide the selection of a subsample enriched in quasielastic nu_mu Fe interactions, containing an estimated 123,000 quasielastic events of incident energies 1 = 2.79 GeV. Four additional subsamples representing topological and kinematic sideband regions to quasielastic scattering are also selected for the purpose of evaluating backgrounds. Comparisons using subsample distributions in four-momentum transfer Q^2 show the Monte Carlo model to be inadequate at low Q^2. Its shortcomings are remedied via inclusion of a Q^2-dependent suppression function for baryon resonance production, developed from the data. A chi-square fit of the resulting Monte Carlo simulation to the shape of the Q^2 distribution for the quasielastic-enriched sample is carried out with the axial-vector mass M_A of the dipole axial-vector form factor of the neutron as a free parameter. The effective M_A which best describes the data is 1.23 +0.13/-0.09 (fit) +0.12/-0.15 (syst.) GeV.

Azimuthally sensitive hanbury brown-twiss interferometry in Au + Au collisions sqrt S sub NN = 200 GeV  

SciTech Connect (OSTI)

We present the results of a systematic study of the shape of the pion distribution in coordinate space at freeze-out in Au+Au collisions at RHIC using two-pion Hanbury Brown-Twiss (HBT) interferometry. Oscillations of the extracted HBT radii vs. emission angle indicate sources elongated perpendicular to the reaction plane. The results indicate that the pressure and expansion time of the collision system are not sufficient to completely quench its initial shape.

Radial Flow in Au+Au Collisions at E=0.25-1.15 A GeV  

E-Print Network [OSTI]

A systematic study of energy spectra for light particles emitted at midrapidity from Au+Au collisions at E=0.25-1.15 A GeV reveals a significant non-thermal component consistent with a collective radial flow. This component is evaluated as a function of bombarding energy and event centrality. Comparisons to Quantum Molecular Dynamics (QMD) and Boltzmann-Uehling-Uhlenbeck (BUU) models are made for different equations of state.

Comment on "Circumstantial Evidence for Critical Behavior in Peripheral Au+Au Collisions at 35 MeV/nucleon"  

E-Print Network [OSTI]

Mastinu et al. recently reported the observation of several positive signals possibly indicating critical behavior in peripheral collisions of Au+Au at $E/A$=35 MeV. In our comment, we examine the choice of variables used to determine the presence (or absence) of critical behavior. We do this by repeating the analysis the work of Mastinu et al. on "data" from a simulation with no critical behavior.

Internal Conversion Coefficients of M1 Gamma Rays of Au199 and Au195  

Science Journals Connector (OSTI)

An attempt has been made to measure the internal conversion coefficients of the M1+E2 radiations of Au199 and Au195 with sufficient accuracy to check the effect of the finite nuclear size on internal conversion in this region of Z. In the case of Au199 a direct comparison of the 158-kev pure E2 transition with the 208-kev M1+E2 radiation was possible. Comparison of the gamma-ray intensities determined from scintillation spectrometry with conversion line intensities measured in a small shaped-field spectrometer yielded K, L, M, total shell coefficients. Comparison of these gamma-ray intensities with conversion line intensities photographically recorded in a higher resolution permanent-field spectrometer led to L-subshell coefficients. The results for the 208-kev transition are: aK=0.71±0.05, aL=0.144±0.01, aLI=0.114±0.007, aLII=0.0227±0.0007, aLIII=0.0065±0.0005, aM=0.042±0.04, and aN+O=0.0083±0.001. The empirical multiplicative factors f by which point-nucleus theoretical values are to be reduced, presumably due to the finite nuclear effect, and the E2 mixing ratio r have been determined: fK=0.762±0.08, fLI=0.78±0.13, fLII=1.00±0.06, fLIII=1.0, and r=0.11±0.03. These results, insofar as they may be compared, are not inconsistent with Sliv's predictions (fK=0.8). An experimental value of 0.60 was found for the screening correction to Rose's M-shell coefficients for this Z and energy region.In the case of Au195 only permanent-field spectrograph measurements of the L- and M-subshell conversion of the 98-kev M1+E2 transition were accurate enough for analysis. A comparison of the experimental ratios with the corresponding theoretical point-nucleus L and M values, the latter being corrected empirically for screening, gives: fLI=0.82±0.10, fLII=0.73±0.20, r=0.014±0.003. In this analysis it has been assumed that LIII shell correction is negligible.More accurate energy values and branching ratios have been obtained. For the radiations of Au199 we find energies of 49.7, 158.3, and 208.0 kev with corresponding relative intensities 8%, 76%, and 16%. The Au195 energies and relative transition rates are 30.8, 98.5, and 129.4 kev, 20%, 72%, and 8%, respectively. Energy values are internally consistent to 0.10 kev.

A global simulation for laser driven MeV electrons in $50\\mu m$-diameter fast ignition targets  

E-Print Network [OSTI]

The results from 2.5-dimensional Particle-in-Cell simulations for the interaction of a picosecond-long ignition laser pulse with a plasma pellet of 50-$\\mu m$ diameter and 40 critical density are presented. The high density pellet is surrounded by an underdense corona and is isolated by a vacuum region from the simulation box boundary. The laser pulse is shown to filament and create density channels on the laser-plasma interface. The density channels increase the laser absorption efficiency and help generate an energetic electron distribution with a large angular spread. The combined distribution of the forward-going energetic electrons and the induced return electrons is marginally unstable to the current filament instability. The ions play an important role in neutralizing the space charges induced by the the temperature disparity between different electron groups. No global coalescing of the current filaments resulted from the instability is observed, consistent with the observed large angular spread of th...

Room-temperature operation of an InGaAsP double-heterostructure laser emitting at 1. 55. mu. m on a Si substrate  

SciTech Connect (OSTI)

The room-temperature operations of an InGaAsP double-heterostructure (DH) laser emitting at 1.55 {mu}m on a Si substrate is reported. A pulsed threshold current as low as 46 mA has been measured for a ridge waveguide laser with a 4 {mu}m strip width and a 200 {mu}m cavity length. This successful laser operation is due to the high crystalline quality of the DH structure with full width at half maximum of x-ray rocking curves as low as 110 arcsec grown on a Si substrate by the organometallic vapor phase epitaxy/vapor mixing epitaxy hybrid method. A correlation between the optical property of an InGaAsP DH and its crystalline quality is also discussed.

Collective flows of light particles in the Au+Au collision at intermediate energies  

E-Print Network [OSTI]

The Skyrme potential energy density functional is introduced into the Ultrarelativistic Quantum Molecular Dynamics (UrQMD) model and the updated version is applied to studying the directed and elliptic flows of light particles (protons, neutrons, deuterons, tritons, $^3$He and $^4$He) in $^{197}$Au+$^{197}$Au collisions at beam energies 150, 250 and 400 MeV/nucleon. The results are compared with the recent FOPI experimental data. It is found that the yields and collective flows of light particles can be described quite well. The influence of the equation of state (EoS), medium-modified nucleon-nucleon elastic cross sections (NNECS) and cluster recognition criteria on the directed and elliptic flows is studied in detail. It is found that the flows of light particles are sensitive to the medium-modified NNECS, but not sensitive to the isospin dependent cluster recognition criteria. It seems difficult, however, even with the new data and calculations, to obtain a more accurate constraint on the nuclear incompressibility $K_0$ than the interval 200-260 MeV.

DISCOVERY OF A RICH CLUSTER AT z = 1.63 USING THE REST-FRAME 1.6 {mu}m 'STELLAR BUMP SEQUENCE' METHOD  

SciTech Connect (OSTI)

We present a new two-color algorithm, the 'Stellar Bump Sequence' (SBS), that is optimized for robustly identifying candidate high-redshift galaxy clusters in combined wide-field optical and mid-infrared (MIR) data. The SBS algorithm is a fusion of the well-tested cluster red-sequence method of Gladders and Yee with the MIR 3.6 {mu}m-4.5 {mu}m cluster detection method developed by Papovich. As with the cluster red-sequence method, the SBS identifies candidate overdensities within 3.6 {mu}m-4.5 {mu}m color slices, which are the equivalent of a rest-frame 1.6 {mu}m stellar bump 'red-sequence'. In addition to employing the MIR colors of galaxies, the SBS algorithm incorporates an optical/MIR (z'-3.6 {mu}m) color cut. This cut effectively eliminates foreground 0.2 mu}m-4.5 {mu}m colors that are similarly red as z > 1.0 galaxies and add noise when searching for high-redshift galaxy overdensities. We demonstrate using the z {approx} 1 GCLASS cluster sample that similar to the red sequence, the stellar bump sequence appears to be a ubiquitous feature of high-redshift clusters, and that within that sample the color of the stellar bump sequence increases monotonically with redshift and provides photometric redshifts accurate to {Delta}z = 0.05. We apply the SBS method in the XMM-LSS SWIRE field and show that it robustly recovers the majority of confirmed optical, MIR, and X-ray-selected clusters at z > 1.0 in that field. Lastly, we present confirmation of SpARCS J022427-032354 at z = 1.63, a new cluster detected with the method and confirmed with 12 high-confidence spectroscopic redshifts obtained using FORS2 on the Very Large Telescope. We conclude with a discussion of future prospects for using the algorithm.

Final Technical Report: First Principles Investigations for the Ensemble Effects of PdAu and PtAu Bimetallic Nanocatalysts  

SciTech Connect (OSTI)

Bimetallic surfaces with tunable chemical properties have attracted broad attention in recent years due to their ample potential for heterogeneous catalysis applications. The local chemical properties of constituents are strongly altered from their parent metals by 'ligand effect', a term encompassing the influences of charge transfer, orbital rehybridization and lattice strain. In comparison to the aforementioned, the 'ensemble effect' associated with particular arrangements of the active constituents have received much less attention, despite their notable importance towards the determination of reactivity and selectivity of bimetallic catalysts. We performed theoretical studies for understanding the ensemble effects on bimetallic catalysis: (i) simulations for the formation of different ensembles on PdAu and PtAu nanoclusters; (ii) studies of the size, shape, and substrate dependence of their electronic properties; and (iii) simulations for model reactions such as CO oxidation, methanol, ethylene and water dehydrogenation on PdAu and PtAu nanoclusters. In close collaboration with leading experimental groups, our theoretical research elucidated the fundamentals of Au based bimetallic nanocatalysts.

AKARI Observations of Brown Dwarfs. IV. Effect of Elemental Abundances to Near-Infrared Spectra between 1.0 and 5.0 {\\mu}m  

E-Print Network [OSTI]

The detection of the CO_2 absorption band at 4.2 {\\mu}m in brown dwarf spectra by AKARI has made it possible to discuss CO_2 molecular abundance in brown dwarf atmospheres. In our previous studies, we found an excess in the 4.2 {\\mu}m CO_2 absorption band of three brown dwarf spectra, and suggested that these deviations were caused by high C and O elemental abundances in their atmospheres. To validate this hypothesis we construct a set of models of brown dwarf atmospheres with various elemental abundance patterns, and investigate the variations of the molecular composition, thermal structure and their effects to the near-infrared spectra between 1.0 and 5.0 {\\mu}m. The 4.2 {\\mu}m CO_2 absorption band in some late-L and T dwarfs taken by AKARI are stronger or weaker than predictions by corresponding models with solar abundance. By comparing CO_2 band in the model spectra to the observed near-infrared spectra, we confirm possible elemental abundance variations among brown dwarfs. We find that the band strength ...

Modeling of plasma-controlled evaporation and surface condensation of Al induced by 1.06 and 0.248 {mu}m laser radiations  

SciTech Connect (OSTI)

Phase transition on the surface of an aluminum target and vapor plasma induced by laser irradiation in the nanosecond regime at the wavelengths of 1.06 {mu}m in the infrared range and 0.248 {mu}m in the ultraviolet range with an intensity of 10{sup 8}-10{sup 9} W/cm{sup 2} in vacuum are analyzed. Special attention is paid to the wavelength dependence of the observed phenomena and the non-one-dimensional effects caused by the nonuniform (Gaussian) laser intensity distribution and the lateral expansion of the plasma plume. A transient two-dimensional model is used which includes conductive heat transfer in the condensed phase, radiative gas dynamics, and laser radiation transfer in the plasma as well as surface evaporation and back condensation at the phase interface. It was shown that distinctions in phase transition dynamics for the 1.06 and 0.248 {mu}m radiations result from essentially different characteristics of the laser-induced plasmas. For the 1.06 {mu}m radiation, evaporation stops after the formation of hot optically thick plasma, can occasionally resume at a later stage of the pulse, and proceeds nonuniformly in the spot area, and the major contribution to the mass removal occurs in the outer part of the irradiated region. Plasma induced by the 0.248 {mu}m laser is colder and partially transparent since it transmits 30%-70% of the incident radiation; therefore evaporation does not stop but continues in the subsonic regime with the Mach number of about 0.1. The amount of evaporated matter that condenses back to the surface is as high as 15%-20% and less than 10% for the 1.06 and 0.248 {mu}m radiations, respectively. For a beam radius smaller than {approx}100 {mu}m, the screening and retarding effect of the plasma weakens because of the lateral expansion, thickness of the removed layer increases, and condensation after the end of the pulse is not observed. Comparison of the numerical and experimental results on the removed layer thickness has shown, in particular, the importance of accounting for the plasma effect to predict the correct trends for radiation intensity and beam radius.

Evaluation of the Au size effect: CO oxidation catalyzed by Au/TiO2.  

SciTech Connect (OSTI)

The size dependence of activity in gold catalysts was examined. Extended X-ray absorption fine structure was used to determine mean particle size, and a flow reactor was used to assess activity of the catalysts for CO oxidation as a function of temperature. A sequence of calcination steps was used to systematically increase the mean Au particle size while repeated measurements of the activity were conducted. In this way the size dependence could be obtained in a single catalyst to avoid differences due to variations in support, synthesis conditions, Au loading, or incidental impurities. Two Au catalysts with different Au loadings were prepared on TiO{sub 2} by deposition precipitation and used for the measurements. For Au particles with mean particle size, d, in the range of 2-10 nm, the measured TOF at 298 K varies as d{sup -1.7{+-}0.2} and d{sup -0.9{+-}0.2} for the 7.2 and 4.5 wt% Au/TiO{sub 2} (P25) catalysts, respectively. Variation between samples emphasizes the conclusion that the activity is sensitive to many factors that may mask the true structure dependence. It is concluded that the observed decrease in activity with increasing particle size beyond 2 nm is controlled by the population of low-coordinate sites, rather than by size-dependent changes in overall electronic structure of the nanoparticle. No evidence was found for maximum activity for small particle sizes, although arguments are offered for why such a maximum was expected but was not observed.

Low frequency noise in the unstable contact region of Au-to-Au microcontact for microelectromechanical system switches  

SciTech Connect (OSTI)

The noise behavior of Au-to-Au microcontact for microelectromechanical system switches has been experimentally studied in the unstable contact region. The results suggest that the electrical conduction remains nonmetallic at the initial stage during contact formation due to the existence of alien films, and traps in the alien layer located at the contact interface could play an important role in determining the conduction noise. The conduction fluctuation induced by electron trapping-detrapping associated with the hydrocarbon layer is found to be an intrinsic noise source contributing to the low frequency noise in the unstable contact region.

Transition from in-plane to out-of-plane azimuthal enhancement inAu+Au collisions  

SciTech Connect (OSTI)

The incident energy at which the azimuthal distributions in semi-central heavy ion collisions change from in-plane to out-of-plane enhancement--E{sub tran} is studied as a function of mass of emitted particles, their transverse momentum and centrality for Au+Au collisions. The analysis is performed in a reference frame rotated with the sidewards flow angle ({Theta}{sub flow}) relative to the beam axis. A systematic decrease of E{sub tran} as function of mass of the reaction products, their transverse momentum and collision centrality is evidenced. The predictions of a microscopic transport model (IQMD) are compared with the experimental results.

Particle Production in Au+Au Collisions at $\\sqrt{s_{NN}}$ = 9.2 GeV  

E-Print Network [OSTI]

In this report we present the first test run results from Au+Au collisions at $\\sqrt{s_{NN}}$ = 9.2 GeV at RHIC. The large acceptance STAR detector has collected ~3k minimum bias collisions during this test run. The azimuthal anisotropy, identified particle spectra, particle ratios and HBT radii are observed to be consistent with the previous measurements from CERN SPS at similar center of mass energies. These results from the lowest collision energy at RHIC demonstrate the STAR detector's readiness to collect high quality data for the proposed Critical Point Search Program which allows us to explore the QCD phase diagram.

Methanol-tolerant carbon aerogel-supported Pt–Au catalysts for direct methanol fuel cell  

Science Journals Connector (OSTI)

Pt–Au nanoparticles supported on carbon aerogel, namely 2:1 has been synthesized by the microwave-assisted polyol process. The structure of Pt–Au nanoparticles is characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The electrochemical property of Pt–Au catalysts for methanol oxidation is evaluated by cyclic voltammetry (CV). The results show that Au-modified Pt catalysts exhibit a high methanol tolerance and improved electrochemical catalytic activity, suggesting that carbon aerogel supported Pt–Au catalysts are better catalysts for the electrochemical oxidation of methanol than conventional Pt catalysts.

Transverse-momentum dependent modification of dynamic texture in central Au+Au collisions at sqrt(sNN) = 200 GeV  

SciTech Connect (OSTI)

Correlations in the hadron distributions produced in relativistic Au+Au collisions are studied in the discrete wavelet expansion method. The analysis is performed in the space of pseudorapidity (|{eta}| {le} 1) and azimuth (full 2{pi}) in bins of transverse momentum (p{sub t}) from 0.14 {le} p{sub t} {le} 2.1 GeV/c. In peripheral Au+Au collisions a correlation structure ascribed to minijet fragmentation is observed. It evolves with collision centrality and p{sub t} in a way not seen before which suggests strong dissipation of minijet fragmentation in the longitudinally-expanding medium.

Effect of the Support on the Electronic Structure of Au Nanoparticles Supported on Transition Metal Carbides: Choice of the Best Substrate for Au Activation  

SciTech Connect (OSTI)

Periodic density functional theory calculations on large supercells have been carried out to investigate the atomic and electronic structure of small gold particles (Au{sub 2}, Au{sub 4}, Au{sub 9}, Au{sub 13}, and Au{sub 14}) supported on the (001) surface of various transition metal carbides (TiC, ZrC, VC, and {delta}-MoC). All the supported Au particles exhibited strong interactions with the C sites of the metal-carbide surfaces. Nevertheless, the interactions between adsorbed Au atoms were attractive, thus ultimately facilitating nucleation of two- or three-dimensional metal particles. The presence of the underlying carbide strongly modified the electronic structure and charge density of the supported metal particles resulting in the experimentally proven improved catalytic performance of the resulting systems as compared with cases where the support is an oxide. The electronic perturbations were quite strong for two-dimensional gold particles directly in contact with the carbide substrates and gradually decreased for two-layer and three-layer thick supported particles. While all the metal carbides examined induced a qualitatively similar perturbation on the supported Au particles, the effect is significantly larger for ZrC thus suggesting that the resulting model catalyst would perform even better than the already tried Au/TiC system.

Observation of dynamic water microadsorption on Au surface  

SciTech Connect (OSTI)

Experimental and theoretical research on water wettability, adsorption, and condensation on solid surfaces has been ongoing for many decades because of the availability of new materials, new detection and measurement techniques, novel applications, and different scales of dimensions. Au is a metal of special interest because it is chemically inert, has a high surface energy, is highly conductive, and has a relatively high melting point. It has wide applications in semiconductor integrated circuitry, microelectromechanical systems, microfluidics, biochips, jewelry, coinage, and even dental restoration. Therefore, its surface condition, wettability, wear resistance, lubrication, and friction attract a lot of attention from both scientists and engineers. In this paper, the authors experimentally investigated Au{sub 2}O{sub 3} growth, wettability, roughness, and adsorption utilizing atomic force microscopy, scanning electron microscopy, reflectance spectrometry, and contact angle measurement. Samples were made using a GaAs substrate. Utilizing a super-hydrophilic Au surface and the proper surface conditions of the surrounding GaAs, dynamic microadsorption of water on the Au surface was observed in a clean room environment. The Au surface area can be as small as 12??m{sup 2}. The adsorbed water was collected by the GaAs groove structure and then redistributed around the structure. A model was developed to qualitatively describe the dynamic microadsorption process. The effective adsorption rate was estimated by modeling and experimental data. Devices for moisture collection and a liquid channel can be made by properly arranging the wettabilities or contact angles of different materials. These novel devices will be very useful in microfluid applications or biochips.

Partonic flow and $?$-meson production in Au+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV  

E-Print Network [OSTI]

We present first measurements of the $\\phi$-meson elliptic flow ($v_{2}(p_{T})$) and high statistics $p_{T}$ distributions for different centralities from $\\sqrt{s_{NN}}$ = 200 GeV Au+Au collisions at RHIC. In minimum bias collisions the $v_{2}$ of the $\\phi$ meson is consistent with the trend observed for mesons. The ratio of the yields of the $\\Omega$ to those of the $\\phi$ as a function of transverse momentum is consistent with a model based on the recombination of thermal $s$ quarks up to $p_{T}\\sim 4$ GeV/$c$, but disagrees at higher momenta. The nuclear modification factor ($R_{CP}$) of $\\phi$ follows the trend observed in the $K^{0}_{S}$ mesons rather than in $\\Lambda$ baryons, supporting baryon-meson scaling. Since $\\phi$-mesons are made via coalescence of seemingly thermalized $s$ quarks in central Au+Au collisions, the observations imply hot and dense matter with partonic collectivity has been formed at RHIC.

We study the beam-energy and system-size dependence of {phi} meson production (using the hadronic decay mode {phi} {yields} K{sup +}K{sup -}) by comparing the new results from Cu + Cu collisions and previously reported Au + Au collisions at {radical}s{sub NN} = 62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented are from midrapidity (|y| < 0.5) for 0.4 < p{sub T} < 5 GeV/c. At a given beam energy, the transverse momentum distributions for {phi} mesons are observed to be similar in yield and shape for Cu + Cu and Au + Au colliding systems with similar average numbers of participating nucleons. The {phi} meson yields in nucleus-nucleus collisions, normalized by the average number of participating nucleons, are found to be enhanced relative to those from p + p collisions with a different trend compared to strange baryons. The enhancement for {phi} mesons is observed to be higher at {radical}s{sub NN} = 200 GeV compared to 62.4 GeV. These observations for the produced {phi}(s{bar s}) mesons clearly suggest that, at these collision energies, the source of enhancement of strange hadrons is related to the formation of a dense partonic medium in high energy nucleus-nucleus collisions and cannot be alone due to canonical suppression of their production in smaller systems.

Neutral Pion Production in Au+Au Collisions at sqrt sNN = 200 GeV  

SciTech Connect (OSTI)

The results of mid-rapidity (0 < y < 0.8) neutral pion spectra over an extended transverse momentum range (1 < p{sub T} < 12 GeV/c) in {radical}s{sub NN} = 200 GeV Au+Au collisions, measured by the STAR experiment, are presented. The neutral pions are reconstructed from photons measured either by the STAR Barrel Electro-Magnetic Calorimeter (BEMC) or by the Time Projection Chamber (TPC) via tracking of conversion electron-positron pairs. Our measurements are compared to previously published {pi}{sup {+-}} and {pi}{sup 0} results. The nuclear modification factors R{sub CP} and R{sub AA} of {pi}{sup 0} are also presented as a function of p{sub T}. In the most central Au+Au collisions, the binary collision scaled {pi}{sup 0} yield at high p{sub T} is suppressed by a factor of about 5 compared to the expectation from the yield of p+p collisions. Such a large suppression is in agreement with previous observations for light quark mesons and is consistent with the scenario that partons suffer considerable energy loss in the dense medium formed in central nucleus-nucleus collisions at RHIC.

Energy Lossand Flow of Heavy Quarks in Au+Au Collisions at root-s=200GeV  

SciTech Connect (OSTI)

The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has measured electrons with 0.3 < p{sub rmT} < 9 GeV/c at midrapidity (|y| < 0.35) from heavy flavor (charm and bottom) decays in Au+Au collisions at {radical}s{sub NN} = 200 GeV. The nuclear modification factor R{sub AA} relative to p+p collisions shows a strong suppression in central Au+Au collisions, indicating substantial energy loss of heavy quarks in the medium produced at RHIC energies. A large azimuthal anisotropy, v{sub 2}, with respect to the reaction plane is observed for 0.5 < p{sub rmT} < 5 GeV/c indicating non-zero heavy flavor elliptic flow. A simultaneous description of R{sub AA}(p{sub rmT}) and v{sub 2}(p{sub rmT}) constrains the existing models of heavy-quark rescattering in strongly interacting matter and provides information on the transport properties of the produced medium. In particular, a viscosity to entropy density ratio close to the conjectured quantum lower bound, i.e. near a perfect fluid, is suggested.

Electroluminescence at 1.54 {mu}m in Si:Er/Si structures grown by sublimation molecular-beam epitaxy  

SciTech Connect (OSTI)

In Si:Er/Si diode structures grown by sublimation molecular-beam epitaxy in a vacuum with a pressure of {approx}10{sup -7} mbar at temperatures 520-580 deg. C, the intensity of room-temperature electroluminescence at 1.54 {mu}m is studied as a function of the concentration and distribution of erbium and donor impurities in the space-charge region (SCR) and the SCR width. Methods for obtaining electroluminescence in diodes with a wide (0.1-1 {mu}m) SCR are developed. The mean free path of electrons with respect to their interaction with Er centers and the threshold energy a free electron needs in order to excite an Er-shell electron are determined. The values of electric-field strength corresponding to breakdown in silicon p-i-n diodes with and without Er doping are obtained experimentally. A model describing the interaction of hot electrons with Er centers is suggested.

Improved Limit on the Rate of the Decay K{sup +} {yields} {pi}{sup +}{mu}{sup +}e{sup -}  

SciTech Connect (OSTI)

We report results of a search for the lepton-family number violating decay K{sup +}{yields}{pi}{sup +}{mu}{sup +}e{sup -} from data collected by experiment E865 in 1996 at the Alternating Gradient Synchroton of Brookhaven National Laboratory. We place an upper limit on the branching ratio at 3.9x10{sup -11} (90% C.L.). Together with results based on data collected in 1995 and an earlier experiment, E777, this result establishes a combined 90% confidence level upper limit on the branching ratio at 2.8x10{sup -11} . We also report a new upper limit on the branching ratio for {pi}{sup 0}{yields}{mu}{sup +}e{sup -} of 3.8x10{sup -10} (90% C.L.). (c) 2000 The American Physical Society.

Frequency stabilization of 1. 5-. mu. m InGaAsP distributed feedback laser to NH/sub 3/ absorption lines  

SciTech Connect (OSTI)

NH/sub 3/ absorption lines due to vibration-rotation transitions are observed at 1.50--1.54 ..mu..m by using an InGaAsP superluminescent diode. A 1.5-..mu..m InGaAsP distributed feedback (DFB) laser is frequency stabilized to an NH/sub 3/ linear absorption line at 15196 A. Frequency stability of sigma(2,tau) = 8 x 10/sup -11/tau/sup -1/ is achieved for an averaging time range of 10 ms< or =tau< or =1 s. Such an absolute frequency-stabilized DFB laser is useful for coherent optical system applications, since it is free from the longitudinal mode jumping which results from a wide range of temperature changes and long-term device degradation.

ESR study of the Kondo effect in Au171 Yb and Au174 Yb  

Science Journals Connector (OSTI)

Recently we have reported on Kondo anomalies in the g-value shift and the relaxation rate of ESR in AuYb. This work was extended (1) to a low Yb concentration of 70 ppm to avoid interaction effects and (2) to 1-GHz experiments, in addition to those at 3 and 9 GHz, to study frequency and magnetic field effects. Experiments were performed down to 80 mK (???kT). We present a theoretical analysis of the longitudinal and transverse dynamic susceptibilities, taking into consideration the finite field and frequency. This analysis is based on the work of Götze and Wölfle, and agrees well with the experiments and shows in particular that in the g-value shift the frequency and field dependence is less important than for the relaxation. The only fit parameter for all relaxation data (different isotopes, concentrations, frequencies, and fields) is the Kondo temperature TK. The theoretical fit explains the relaxation data quite well; however, the fit of the g-value shift yields a different TK.

Gain and order scheduling of fractional order (FO) PI{\\lambda}D{\\mu} controllers are studied in this paper considering four different classes of higher order processes. The mapping between the optimum PID/FOPID controller parameters and the reduced order process models are done using Radial Basis Function (RBF) type Artificial Neural Network (ANN). Simulation studies have been done to show the effectiveness of the RBFNN for online scheduling of such controllers with random change in set-point and process parameters.

THE CARNEGIE HUBBLE PROGRAM: THE LEAVITT LAW AT 3.6 AND 4.5 {mu}m IN THE MILKY WAY  

SciTech Connect (OSTI)

The Carnegie Hubble Program (CHP) is designed to calibrate the extragalactic distance scale using data from the post-cryogenic era of the Spitzer Space Telescope. The ultimate goal of the CHP is a systematic improvement in the distance scale leading to a determination of the Hubble constant to within an accuracy of 2%. This paper focuses on the measurement and calibration of the Galactic Cepheid period-luminosity (PL, Leavitt) relation using the warm Spitzer/IRAC 1 and 2 bands at 3.6 and 4.5 {mu}m. We present photometric measurements covering the period range 4-70 days for 37 Galactic Cepheids. Data at 24 phase points were collected for each star. Three PL relations of the form M = a(log (P) - 1) + b are derived. The method adopted here takes the slope a to be -3.31, as determined from the Spitzer Large Magellanic Cloud (LMC) data of Scowcroft et al. Using the geometric Hubble Space Telescope guide-star distances to 10 Galactic Cepheids, we find a calibrated 3.6 {mu}m PL zero point of -5.80 {+-} 0.03. Together with our value for the LMC zero point, we determine a reddening-corrected distance modulus of 18.48 {+-} 0.04 mag to the LMC. The mid-IR period-color diagram and the [3.6]-[4.5] color variation with phase are interpreted in terms of CO absorption at 4.5 {mu}m. This situation compromises the use of the 4.5 {mu}m data for distance determinations.

THE COMPTON-THICK SEYFERT 2 NUCLEUS OF NGC 3281: TORUS CONSTRAINTS FROM THE 9.7 {mu}m SILICATE ABSORPTION  

SciTech Connect (OSTI)

We present mid-infrared (mid-IR) spectra of the Compton-thick Seyfert 2 galaxy NGC 3281, obtained with the Thermal-Region Camera Spectrograph at the Gemini-South telescope. The spectra present a very deep silicate absorption at 9.7 {mu}m, and [S IV] 10.5 {mu}m and [Ne II] 12.7 {mu}m ionic lines, but no evidence of polycyclic aromatic hydrocarbon emission. We find that the nuclear optical extinction is in the range 24 mag {<=} A{sub V} {<=} 83 mag. A temperature T = 300 K was found for the blackbody dust continuum component of the unresolved 65 pc nucleus and the region at 130 pc SE, while the region at 130 pc NW reveals a colder temperature (200 K). We describe the nuclear spectrum of NGC 3281 using a clumpy torus model that suggests that the nucleus of this galaxy hosts a dusty toroidal structure. According to this model, the ratio between the inner and outer radius of the torus in NGC 3281 is R{sub 0}/R{sub d} = 20, with 14 clouds in the equatorial radius with optical depth of {tau}{sub V} = 40 mag. We would be looking in the direction of the torus equatorial radius (i = 60{sup 0}), which has outer radius of R{sub 0} {approx} 11 pc. The column density is N{sub H} {approx} 1.2 x 10{sup 24} cm{sup -2} and the iron K{alpha} equivalent width ({approx}0.5-1.2 keV) is used to check the torus geometry. Our findings indicate that the X-ray absorbing column density, which classifies NGC 3281 as a Compton-thick source, may also be responsible for the absorption at 9.7 {mu}m providing strong evidence that the silicate dust responsible for this absorption can be located in the active galactic nucleus torus.

Structural and phonon transmission study of Ge-Au-Ge eutectically bonded interfaces  

SciTech Connect (OSTI)

This thesis presents a structural analysis and phonon transparency investigation of the Ge-Au-Ge eutectic bond interface. Interface development was intended to maximize the interfacial ballistic phonon transparency to enhance the detection of the dark matter candidate WIMPs. The process which was developed provides an interface which produces minimal stress, low amounts of impurities, and insures Ge lattice continuity through the interface. For initial Au thicknesses of greater than 1,000 {angstrom} Au per substrate side, eutectic epitaxial growth resulted in a Au dendritic structure with 95% cross sectional and 90% planar Au interfacial area coverages. In sections in which Ge bridged the interface, lattice continuity across the interface was apparent. Epitaxial solidification of the eutectic interface with initial Au thicknesses < 500 A per substrate side produced Au agglomerations thereby reducing the Au planar interfacial area coverage to as little as 30%. The mechanism for Au coalescence was attributed to lateral diffusion of Ge and Au in the liquid phase during solidification. Phonon transmission studies were performed on eutectic interfaces with initial Au thicknesses of 1,000 {angstrom}, 500 {angstrom}, and 300 {angstrom} per substrate side. Phonon imaging of eutectically bonded samples with initial Au thicknesses of 300 {angstrom}/side revealed reproducible interfacial percent phonon transmissions from 60% to 70%. Line scan phonon imaging verified the results. Phonon propagation TOF spectra distinctly showed the predominant phonon propagation mode was ballistic. This was substantiated by phonon focusing effects apparent in the phonon imaging data. The degree of interface transparency to phonons and resulting phonon propagation modes correlate with the structure of the interface following eutectic solidification. Structural studies of samples with initial Au thickness of 1,000 {angstrom}/side appear to correspond with the phonon transmission study.

Surface Crystallization in a Liquid AuSi Alloy  

SciTech Connect (OSTI)

X-ray measurements reveal a crystalline monolayer at the surface of the eutectic liquid Au{sub 82}Si{sub 18}, at temperatures above the alloy's melting point. Surface-induced atomic layering, the hallmark of liquid metals, is also found below the crystalline monolayer. The layering depth, however, is threefold greater than that of all liquid metals studied to date. The crystallinity of the surface monolayer is notable, considering that AuSi does not form stable bulk crystalline phases at any concentration and temperature and that no crystalline surface phase has been detected thus far in any pure liquid metal or nondilute alloy. These results are discussed in relation to recently suggested models of amorphous alloys.

Thermal diffusion in Au?WTi?Pd metallization on silicon  

Science Journals Connector (OSTI)

This paper presents the results of investigation of thermal diffusion in Au?Wti?Pd metallization on (111) n-Si. Thin films were deposited by dc sputtering to the thickness of 50 (Pd), 100–200 (WTi) and 70–200 nm (Au). After deposition the samples were subjected to thermal treatments vacuum 1 × 10?5 mbar, at temperatures up to 600°C. Characterization included RBS, AES, XRD and SEM structural analysis and sheet resistivity measurements. During annealing up to 450°C diffusion occurs only at the Pd?Si interface, at 500°C other components interdiffuse at isolated areas of the samples and at 600°C there is total interdiffusion on components. Thermal degradation oftthe \\{WTi\\} diffusion barrier is enhanced by the growth of Pd2Si phase, during which silicon is released from the substrate and mechanical stress is introduced. Better diffusion barrier properties were obtained when \\{WTi\\} films were deposited in nitrogen or oxygen atmosphere.

Au/PO43-/TiO2 and PO43-/Au/TiO2 catalysts for CO oxidation: effect of synthesis details on catalytic performance  

SciTech Connect (OSTI)

Supported gold catalysts are active for CO oxidation, but the high-temperature deactivation is a shortcoming that may constrain their applications. Herein, we attempted to address this problem by using phosphate-doped Au/TiO{sub 2} synthesized via two routes. In route I, Au/PO{sub 4}{sup 3-}/TiO{sub 2} catalysts were prepared by treating TiO{sub 2} (Degussa P25) with diluted H{sub 3}PO{sub 4}, followed by loading gold via deposition-precipitation. In route II, PO{sub 4}{sup 3-}/Au/TiO{sub 2} catalysts were prepared by treating H{sub 2}-reduced Au/TiO{sub 2} with diluted H{sub 3}PO{sub 4}. These catalysts were systematically pretreated at 200 or 500 C before reaction testing. The overall CO conversion on 200 C-pretreated Au/PO43-/TiO2 or PO43-/Au/TiO2 was always lower than that on 200 C-pretreated Au/TiO2. However, the advantage of the phosphate addition became apparent after thermal treatment at a higher temperature. Both Au/PO43-/TiO2 and PO43-/Au/TiO2 pretreated at 500 C retained significant activities at room temperature, whereas 500 C-pretreated Au/TiO2 lost its activity. Control experiments and catalyst characterization were performed to investigate the impact of synthesis details on catalytic performance.

Entropy in C12+Au197 at intermediate energies  

Science Journals Connector (OSTI)

Isotopically resolved yields of complex particles and fragments from the reaction C12 on Au197 at three bombarding energies EA=30,48, and 84 MeV were measured. Specific entropies SA were derived from the isotope yield ratios using a quantum statistical model. The entropy increases with the bombarding energy in the case of preequilibrium light particles but, for intermediate mass fragments, has an energy-independent value of SA?2.3.

Collective radial expansion in Au+Au reactions from 0.25 to 2 GeV/nucleon  

Science Journals Connector (OSTI)

A nonthermal expansive component has recently been interpreted from the observed light fragment spectra in Au + Au collisions. We have used the BUU transport model to generate several different freezeout surfaces and applied a coalescence algorithm to approximate the complete final state. We vary the microscopic details leading to specific equations of state, reduce cross sections, and isolate the effect of compression on the spectra for protons and helium isotopes. We find a radial flow signal consistent with experiment in the energy range 0.25A to 1.15A GeV, but find it to be rather insensitive to the microscopic details of the model calculations. © 1996 The American Physical Society.

Entropy production in the Au+Au reaction between 150A and 800A MeV  

Science Journals Connector (OSTI)

The entropy per nucleon (S/A) has been extracted for the Au [(150–800)A MeV] + Au reaction by using the phase I setup of the 4? facility at GSI, Darmstadt. The entropy has been obtained from the comparison of various observables characterizing the dM/dZ fragment multiplicity distributions, extending up to Z?15, with those calculated with the quantum statistical model. It is the first time that S/A values are determined by considering the full ensemble of charged products detected in the reaction. Consistent values of S/A are found from different methods. These entropy values are shown to be fairly independent of the volume of the ‘‘participant’’ region considered. They are somewhat lower than those extracted in earlier works but are in good agreement with hydrodynamic calculations and suggest a low viscosity for the hot and dense nuclear matter.

Beam-Energy Dependence of Directed Flow of Protons, Antiprotons and Pions in Au+Au Collisions  

E-Print Network [OSTI]

Rapidity-odd directed flow($v_1$) measurements for charged pions, protons and antiprotons near mid-rapidity ($y=0$) are reported in $\\sqrt{s_{NN}} =$ 7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV Au + Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider (RHIC). At intermediate impact parameters, the proton and net-proton slope parameter $dv_1/dy|_{y=0}$ shows a minimum between 11.5 and 19.6 GeV. In addition, the net-proton $dv_1/dy|_{y=0}$ changes sign twice between 7.7 and 39 GeV. The proton and net-proton results qualitatively resemble predictions of a hydrodynamic model with a first-order phase transition from hadronic matter to deconfined matter, and differ from hadronic transport calculations.

Scaling Properties of Hyperon Production in Au + Au Collisions at sqrt sNN = 200 GeV  

SciTech Connect (OSTI)

We present the scaling properties of Lambda, Xi, and their anti-particles produced at mid-rapidity in Au+Au collisions at RHIC at psNN = 200 GeV. The yield of multi-strange baryons per participant nucleon increases from peripheral to central collisions more rapidly than the Lambda yield, which appears to correspond to an increasing strange quark density of matter produced. The value of the strange phase space occupancy factor gamma s, obtained from a thermal model fit to the data, approaches unity for the most central collisions. We also show that the nuclear modification factors, RCP, of Lambda and Xi are consistent with each other and with that of protons in the transverse momentum range2.0< pT< 5.0 GeV/c. This scaling behaviour is consistent with a scenario of hadron formation from constituent quark degrees of freedom through quark recombination or coalescence.

Detailed HBT measurements with respect to the event plane and collision energy in Au+Au collisions at PHENIX  

E-Print Network [OSTI]

The azimuthal dependence of 3D HBT radii relative to the event plane gives us information about the source shape at freeze-out. It also provides information on the system's evolution by comparing it to the initial source shape. In recent studies, higher harmonic event planes and flow have been measured at RHIC and the LHC, which result primarily from spatial fluctuations of the initial density across the collision area. If the shape caused by initial fluctuations still exists at freeze-out, the HBT measurement relative to higher order event plane may show these features. We present recent results of azimuthal HBT measurements relative to $2^{nd}$- and $3^{rd}$-order event planes in Au+Au 200 GeV collisions with the PHENIX experiment. Recent HBT measurements at lower energies will be also shown and compared with the 200 GeV result.

Measurements of transverse energy distributions in Au+Au collisions at $\\sqrt{s_{NN}}= 200$ GeV  

E-Print Network [OSTI]

Transverse energy ($E_T$) distributions have been measured for Au+Au collisions at $\\sqrt{s_{NN}}= 200$ GeV by the STAR collaboration at RHIC. $E_T$ is constructed from its hadronic and electromagnetic components, which have been measured separately. $E_T$ production for the most central collisions is well described by several theoretical models whose common feature is large energy density achieved early in the fireball evolution. The magnitude and centrality dependence of $E_T$ per charged particle agrees well with measurements at lower collision energy, indicating that the growth in $E_T$ for larger collision energy results from the growth in particle production. The electromagnetic fraction of the total $E_T$ is consistent with a final state dominated by mesons and independent of centrality.

Transverse energy measurement in sqrt{s_{NN}} = 62.4 GeV Au+Au collisions at RHIC  

E-Print Network [OSTI]

The transverse energy distributions ($E_{T}$) have been measured for Au + Au collisions at $\\sqrt{s_{NN}} = 62.4$ GeV by the STAR experiment at RHIC. They have been obtained from two measurements, the hadronic transverse energy ($E_{T}^{had}$) and the electromagnetic transverse energy($E_{T}^{em}$). $E_{T}^{had}$ has been measured from the tracks obtained by Time Projection Chamber (TPC) excluding the electrons and positrons. $E_{T}^{em}$ has been obtained by the STAR Barrel Electromagetic Calorimeter (BEMC) which measures the energy of electrons, positrons and photons. The measure of transverse energy gives an estimate of the energy density of the fireball produced in heavy ion collisions. $E_{T}$ per participant pair gives information about the production mechanism of particles.

Elliptic Flow: Transition from Out-of-Plane to In-Plane Emission in Au + Au Collisions  

SciTech Connect (OSTI)

We have measured the proton elliptic flow excitation function for the Au+Au system spanning the beam energy range (2{endash}8)A GeV . The excitation function shows a transition from negative to positive elliptic flow at a beam energy, E{sub tr}{approximately}4A GeV . Detailed comparisons with calculations from a relativistic Boltzmann equation are presented. The comparisons suggest a softening of the nuclear equation of state from a stiff form (K{approximately}380 MeV ) at low beam energies (E{sub beam}{le}2A GeV ) to a softer form (K{approximately}210 MeV ) at higher energies (E{sub beam}{ge}4A GeV ) where the calculated baryon density {rho}{approximately}4{rho}{sub 0} . {copyright} {ital 1999} {ital The American Physical Society}

Examination of charge transfer in Au/YSZ for high-temperature optical gas sensing  

SciTech Connect (OSTI)

Au-nanoparticle incorporated oxide thin film materials demonstrate significant promise as functionalsensor materials for high temperature optical gas sensing in severe environments relevant for fossil andnuclear based power generation. The Au/yttria-stabilized zirconia (YSZ) system has been extensivelystudied in the literature and serves as a model system for fundamental investigations that seek to betterunderstand the mechanistic origin of the plasmonic gas sensing response. In this work, X-ray photoelec-tron spectroscopy techniques are applied to Au/YSZ films in an attempt to provide further experimentalevidence for a proposed sensing mechanism involving a change in free carrier density of Au nanoparticles due to charge transfer.

Nano scale phase separation in Au-Ge system on ultra clean Si(100) surfaces  

SciTech Connect (OSTI)

We report on the phase separation in Au-Ge system leading to the formation of lobe-lobe (bi-lobed) Au-Ge nanostructures under ultra high vacuum (UHV) conditions ({approx_equal}3 x 10{sup -10} mbar) on clean Si(100) surfaces. For this study, {approx_equal}2.0 nm thick Au samples were grown on the substrate surface by molecular beam epitaxy. Thermal annealing was carried out inside the UHV chamber at temperature {approx_equal}500 deg. C and following this, nearly square shaped Au{sub x}Si{sub 1-x} nano structures of average length {approx_equal}48 nm were formed. A {approx_equal}2 nm Ge film was further deposited on the above surface while the substrate was kept at a temperature of {approx_equal}500 deg. C. Well ordered Au-Ge nanostructures where Au and Ge residing side by side (lobe-lobe structures) were formed. In our systematic studies, we show that, gold-silicide nanoalloy formation at the substrate (Si) surface is necessary for forming phase separated Au-Ge bilobed nanostructures. These results show that the Au-Ge bonding is unstable in nature. Electron microscopy (TEM, STEM-EDS, SEM) studies were carried out to determine the structure of Au-Ge nano systems. Rutherford backscattering spectrometry measurements show gold inter-diffusion into substrate while it is absent for Ge.

Measurement of the spectroscopic quadrupole moment of Au186: Experimental verification of the large prolate deformation of the186Au ground state  

Science Journals Connector (OSTI)

We report the first on-line measurements of quadrupole-interaction-resolved nuclear magnetic resonance on oriented nuclei. The 10-min Au186 activity was obtained as daughter after cold implantation of mass-separated Hg186 into a hcp Co single crystal at the NICOLE facility at ISOLDE-3 (CERN). The quadrupole interaction of Co186(hcp) was fully resolved, and the spectroscopic quadrupole moment of Au186 was determined to be Q=+3.12(20) b. This implies ?2=+0.246(16), proving the large prolate deformation of the Au186 ground state.

EXPLAINING THE [C II]157.7 {mu}m DEFICIT IN LUMINOUS INFRARED GALAXIES-FIRST RESULTS FROM A HERSCHEL/PACS STUDY OF THE GOALS SAMPLE  

SciTech Connect (OSTI)

We present the first results of a survey of the [C II]157.7 {mu}m emission line in 241 luminous infrared galaxies (LIRGs) comprising the Great Observatories All-sky LIRG Survey (GOALS) sample, obtained with the PACS instrument on board the Herschel Space Observatory. The [C II] luminosities, L{sub [C{sub II]}}, of the LIRGs in GOALS range from {approx}10{sup 7} to 2 Multiplication-Sign 10{sup 9} L{sub Sun }. We find that LIRGs show a tight correlation of [C II]/FIR with far-IR (FIR) flux density ratios, with a strong negative trend spanning from {approx}10{sup -2} to 10{sup -4}, as the average temperature of dust increases. We find correlations between the [C II]/FIR ratio and the strength of the 9.7 {mu}m silicate absorption feature as well as with the luminosity surface density of the mid-IR emitting region ({Sigma}{sub MIR}), suggesting that warmer, more compact starbursts have substantially smaller [C II]/FIR ratios. Pure star-forming LIRGs have a mean [C II]/FIR {approx} 4 Multiplication-Sign 10{sup -3}, while galaxies with low polycyclic aromatic hydrocarbon (PAH) equivalent widths (EWs), indicative of the presence of active galactic nuclei (AGNs), span the full range in [C II]/FIR. However, we show that even when only pure star-forming galaxies are considered, the [C II]/FIR ratio still drops by an order of magnitude, from 10{sup -2} to 10{sup -3}, with {Sigma}{sub MIR} and {Sigma}{sub IR}, implying that the [C II]157.7 {mu}m luminosity is not a good indicator of the star formation rate (SFR) for most local LIRGs, for it does not scale linearly with the warm dust emission most likely associated to the youngest stars. Moreover, even in LIRGs in which we detect an AGN in the mid-IR, the majority (2/3) of galaxies show [C II]/FIR {>=} 10{sup -3} typical of high 6.2 {mu}m PAH EW sources, suggesting that most AGNs do not contribute significantly to the FIR emission. We provide an empirical relation between the [C II]/FIR and the specific SFR for star-forming LIRGs. Finally, we present predictions for the starburst size based on the observed [C II] and FIR luminosities which should be useful for comparing with results from future surveys of high-redshift galaxies with ALMA and CCAT.

Novel Au-TiC Catalysts for CO Oxidation and Desulfurization Processes  

SciTech Connect (OSTI)

Recent articles dealing with the physical and chemical properties of novel Au-TiC catalysts are reviewed. High-resolution photoemission, scanning tunneling microscopy and first-principles periodic density-functional calculations were used to study the deposition of gold on a TiC(0 0 1) surface. Gold grows forming two-dimensional (very low coverage) and three-dimensional (medium and large coverage) islands on the carbide substrate. A positive shift in the binding energy of the C 1s core level is observed after the deposition of Au on TiC(0 0 1). The results of the density-functional calculations corroborate the formation of Au-C bonds. In general, the bond between Au and the TiC(0 0 1) surface exhibits very little ionic character, but there is a substantial polarization of electrons around Au that facilitates bonding of the adatoms with electron-acceptor molecules (CO, O{sub 2}, C{sub 2}H{sub 4}, SO{sub 2}, thiophene, etc.). Experimental measurements indicate that Au/TiC(0 0 1) is a very good catalysts for the oxidation of CO, the destruction of SO{sub 2} and the hydrodesulfurization of thiophene. At temperatures below 200 K, Au/TiC(0 0 1) is able to perform the 2CO + O{sub 2} {yields} 2CO{sub 2} reaction and the full decomposition of SO{sub 2}. Furthermore, in spite of the very poor hydrodesulfurization performance of TiC(0 0 1) or Au(1 1 1), a Au/TiC(0 0 1) surface displays a hydrodesulfurization activity higher than that of conventional Ni/MoS{sub x} catalysts. Metal carbides are excellent supports for enhancing the chemical reactivity of gold. The Au/TiC system is more chemically active than systems generated by depositing Au nanoparticles on oxide surfaces.

Interface Reactions and Electrical Characteristics of Au/GaSb Contacts  

SciTech Connect (OSTI)

The reaction of Au with GaSb occurs at a relatively low temperature (100 C). Upon annealing, a AuSb{sub 2} compound and several Au-Ga phases are produced. Phase transitions occur toward higher Ga concentration with increasing annealing temperatures. Furthermore, the depth of the contact also increases with increased annealing temperature. They found that the AuSb{sub 2} compound forms on the GaSb surface, with the compound crystal partially ordered with respect to the substrate. The transition of Schottky- to ohmic-contact behavior in Au/n-type GaSb occurs simultaneously with the formation of the AuGa compound at about a 250 C annealing temperature. This ohmic contact forms without the segregation of dopants at the metallic compound/GaSb interface. Therefore it is postulated that transition from Schottky- to ohmic-contact behavior is obtained through a series of tunneling transitions of electrons through defects in the depletion region in the Au/n-type GaSb contacts. Contact resistivities of 6-7 x 10{sup -6} {Omega}-cm{sup 2} were obtained with the annealing temperature between 300 and 350 C for 30 seconds. In Au/p-type GaSb contacts, the resistivity was independent of the annealing temperature. This suggested that the carrier transport in p-type contact dominated by thermionic emission.

Systematic Study of Azimuthal Anisotropy in Cu$+$Cu and Au$+$Au Collisions at $\\sqrt{s_{_{NN}}} = 62.4$ and 200~GeV  

E-Print Network [OSTI]

We have studied the dependence of azimuthal anisotropy $v_2$ for inclusive and identified charged hadrons in Au$+$Au and Cu$+$Cu collisions on collision energy, species, and centrality. The values of $v_2$ as a function of transverse momentum $p_T$ and centrality in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$=200~GeV and 62.4~GeV are the same within uncertainties. However, in Cu$+$Cu collisions we observe a decrease in $v_2$ values as the collision energy is reduced from 200 to 62.4~GeV. The decrease is larger in the more peripheral collisions. By examining both Au$+$Au and Cu$+$Cu collisions we find that $v_2$ depends both on eccentricity and the number of participants, $N_{\\rm part}$.

A SEARCH FOR C II 158 {mu}m LINE EMISSION IN HCM 6A, A Ly{alpha} EMITTER AT z = 6.56  

SciTech Connect (OSTI)

We report a Plateau de Bure Interferometer search for C II 158 {mu}m emission from HCM 6A, a lensed Ly{alpha} emitter (LAE) at z = 6.56. Our non-detections of C II 158 {mu}m line emission and 1.2 mm radio continuum emission yield 3{sigma} limits of L{sub CII} < 6.4 x 10{sup 7} x ({Delta}V/100 km s{sup -1}){sup 1/2} L{sub Sun} for the C II 158 {mu}m line luminosity and S{sub 1.2mm} < 0.68 mJy for the 1.2 mm flux density. The local conversion factor between L{sub CII} and the star formation rate (SFR) yields an SFR < 4.7 M{sub Sun} yr{sup -1}, Almost-Equal-To 2 times lower than that inferred from the ultraviolet (UV) continuum, suggesting that the local factor may not be applicable in high-z LAEs. The non-detection of 1.2 mm continuum emission yields a total SFR < 28 M{sub Sun} yr{sup -1}; any obscured star formation is thus within a factor of two of the visible star formation. Our best-fit model to the rest-frame UV/optical spectral energy distribution of HCM 6A yields a stellar mass of 1.3 Multiplication-Sign 10{sup 9} M{sub Sun} and an SFR of Almost-Equal-To 10 M{sub Sun} yr{sup -1}, with negligible dust obscuration. We fortuitously detect CO J = 3-2 emission from a z = 0.375 galaxy in the foreground cluster A370, and obtain a CO line luminosity of L'(CO) > (8.95 {+-} 0.79) Multiplication-Sign 10{sup 8} K km s{sup -1} pc{sup 2} and a molecular gas mass of M(H{sub 2}) > (4.12 {+-} 0.36) Multiplication-Sign 10{sup 9} M{sub Sun }, for a CO-to-H{sub 2} conversion factor of 4.6 M{sub Sun} (K km s{sup -1} pc{sup 2}){sup -1}.

Crystal growth behaviour in Au-ZnO nanocomposite under different annealing environments and photoswitchability  

SciTech Connect (OSTI)

The growth of gold nanoparticles and ZnO nanorods in atom beam co-sputtered Au-ZnO nanocomposite (NC) system by annealing at two different ambient conditions is demonstrated in this work. Annealing in a furnace at 600 Degree-Sign C (air environment) confirmed the formation of ZnO nanorods surrounded with Au nanoparticles. In-situ annealing inside a transmission electron microscope (TEM) led to the formation of gold nanocrystals with different polygonal shapes. TEM micrographs were obtained in real time at intermediate temperatures of 300 Degree-Sign C, 420 Degree-Sign C, and 600 Degree-Sign C under vacuum. The growth mechanisms of Au nanocrystals and ZnO nanorods are discussed in the framework of Au-Zn eutectic and Zn-melting temperatures in vacuum and air, respectively. Current-voltage responses of Au-ZnO NC nanorods in dark as well as under light illumination have been investigated and photoswitching in Au-ZnO NC system is reported. The photoswitching has been discussed in terms of Au-ZnO band-diagram.

Understanding the effect of halide poisoning in CO oxidation over Au/TiO[subscript 2  

SciTech Connect (OSTI)

The effect of halide poisoning of Au/TiO{sub 2} catalysts in low temperature CO oxidation was investigated using bromide as the poison and a combination of X-ray absorption spectroscopy (XANES and EXAFS), quantitative CO adsorption, and catalytic measurements. It was found that halide prevented full reduction of cationic Au by displacing oxyhydroxy ligands and remaining bound to Au during low temperature reduction, causing a reduction in catalytic activity. On reduced Au samples, bromide (likely as NaBr molecule) was preferentially adsorbed on Au and not on TiO{sub 2}, and suppressed both the adsorption of CO and the catalytic activity. At low Br contents, each adsorbed Br suppressed adsorption of three CO, suggesting that Br was adsorbed on three-fold sites but the effect decreased with increasing Br content possibly due to crowding of adsorbed Br. When 5--10% of the Au was bound to Br, the catalytic activity was completely blocked, although {approx}35% of the original CO adsorption capacity remained. The data suggest that not all CO adsorption sites are catalytic active sites, and are consistent with the perimeter Au atoms at/near the particle-support interface (perimeter) being active sites.

Glycerol Hydrogenolysis on Carbon-Supported PtRu and AuRu Bimetallic Catalysts  

SciTech Connect (OSTI)

Bimetallic PtRu and AuRu catalysts were prepared by a surface redox method in which Pt or Au was deposited onto the surface of carbon-supported Ru nanoparticles with an average diameter of 2-3 nm. Characterization by H2 chemisorption, analytical TEM, and X-ray absorption spectroscopy at the Ru K-edge, Pt LIII-edge, and Au LIII-edge confirmed that Pt and Au were successfully deposited onto Ru without disrupting the Ru particles. Depression of the ethane hydrogenolysis rate over Ru after addition of Au provided further evidence of successful deposition. The bimetallic particles were subsequently evaluated in the aqueous-phase hydrogenolysis of glycerol at 473 K and 40 bar H2 at neutral and elevated pH. Although monometallic Pt and Ru exhibited different activities and selectivities to products, the bimetallic PtRu catalyst functioned more like Ru. A similar result was obtained for the AuRu bimetallic catalyst. The PtRu catalyst appeared to be stable under the aqueous-phase reaction conditions, whereas the AuRu catalyst was altered by the harsh conditions. Gold appeared to migrate off the Ru and agglomerate on the carbon during the reaction in liquid water.

Measurement of {nu}{sub {mu}} and {nu}{sub e} Events in an Off-Axis Horn-Focused Neutrino Beam  

SciTech Connect (OSTI)

We report the first observation of off-axis neutrino interactions in the MiniBooNE detector from the NuMI beam line at Fermilab. The MiniBooNE detector is located 745 m from the NuMI production target, at 110 mrad angle (6.3 deg.) with respect to the NuMI beam axis. Samples of charged-current quasielastic {nu}{sub {mu}} and {nu}{sub e} interactions are analyzed and found to be in agreement with expectation. This provides a direct verification of the expected pion and kaon contributions to the neutrino flux and validates the modeling of the NuMI off-axis beam.

Leading order hadronic contributions to a{sub {mu}} and {alpha}{sub QED} from N{sub f} = 2 + 1 + 1 twisted mass fermions  

SciTech Connect (OSTI)

We present the first four-flavour lattice calculation of the leading-order hadronic vacuum polarisation contribution to the anomalous magnetic moment of the muon, a{sub {mu}}{sup hvp}, and the hadronic running of the QED coupling constant, {Delta}{alpha}{sup hvp}{sub QED}(Q{sup 2}). In the heavy sector a mixed-action setup is employed. The bare quark masses are determined from matching the K- and D-meson masses to their physical values. Several light quark masses are used in order to yield a controlled extrapolation to the physical pion mass by utilising a recently proposed improved method. We demonstrate that this method also works in the four-flavour case.

Above room-temperature operation of InAs/AlGaSb superlattice quantum cascade lasers emitting at 12 {mu}m  

SciTech Connect (OSTI)

The authors report on above-room-temperature operation of InAs/AlGaSb quantum cascade lasers emitting at 12 {mu}m. The laser structures are grown on a n-InAs (100) substrate using solid-source molecular beam epitaxy. An InAs/AlGaSb superlattice is used as an active part and an InAs double plasmon waveguide is used for optical confinement. Results show that increased doping concentration in the injection part of the active region expands the current operation range of the devices, allowing laser operation at and above room temperature. The observed threshold current density is 4.0 kA/cm{sup 2} at 300 K; the maximum operation temperature is 340 K.

Diode laser measurements of H[sub 2]O line intensities and self-broadening coefficients in the 1. 4-[mu]m region  

SciTech Connect (OSTI)

Precise knowledge of water vapor radiative properties in the infrared spectrum is needed for many applications. Such applications include atmospheric sounding experiments, radiative sensing of combustion processes, and optical diagnostics for gas-dynamic and aerodynamic studies. Spectrally resolved measurements of pure water vapor absorption spectra have been performed with a tunable diode laser. The laser, a distributed feedback InGaAsP diode, emits in the 1.4-[mu]m region. A total of 12 lines were studied corresponding to rovibrational transitions within the [nu][sub 1] + [nu][sub 3] and 2[nu][sub 1] vibrational bands. A Voigt profile analysis of lineshape is used to infer both intensities and self-collision-broadening coefficients of the water vapor. Good agreements is found between the observed line intensities and those recently measured by Toth. These results are apparently the first published measurements of the broadening coefficient within this spectral range.

FIRST DETECTIONS OF THE [N II] 122 {mu}m LINE AT HIGH REDSHIFT: DEMONSTRATING THE UTILITY OF THE LINE FOR STUDYING GALAXIES IN THE EARLY UNIVERSE  

SciTech Connect (OSTI)

We report the first detections of the [N II] 122 {mu}m line from a high-redshift galaxy. The line was strongly (>6{sigma}) detected from SMMJ02399-0136, and H1413+117 (the Cloverleaf QSO) using the Redshift (z) and Early Universe Spectrometer on the Caltech Submillimeter Observatory. The lines from both sources are quite bright with line to far-infrared (FIR) continuum luminosity ratios that are {approx}7.0 x 10{sup -4} (Cloverleaf) and 2.1 x 10{sup -3} (SMMJ02399). With ratios 2-10 times larger than the average value for nearby galaxies, neither source exhibits the line-to-continuum deficits seen in nearby sources. The line strengths also indicate large ionized gas fractions, {approx}8%-17% of the molecular gas mass. The [O III]/[N II] line ratio is very sensitive to the effective temperature of ionizing stars and the ionization parameter for emission arising in the narrow-line region (NLR) of an active galactic nucleus (AGN). Using our previous detection of the [O III] 88 {mu}m line, the [O III]/[N II] line ratio for SMMJ02399-0136 indicates that the dominant source of the line emission is either stellar H II regions ionized by O9.5 stars, or the NLR of the AGN with ionization parameter log(U) = -3.3 to -4.0. A composite system, where 30%-50% of the FIR lines arise in the NLR also matches the data. The Cloverleaf is best modeled by a superposition of {approx}200 M82-like starbursts accounting for all of the FIR emission and 43% of the [N II] line. The remainder may come from the NLR. This work demonstrates the utility of the [N II] and [O III] lines in constraining properties of the ionized medium.

FIRST DETECTION OF THE [O III] 88 {mu}m LINE AT HIGH REDSHIFTS: CHARACTERIZING THE STARBURST AND NARROW-LINE REGIONS IN EXTREME LUMINOSITY SYSTEMS  

SciTech Connect (OSTI)

We have made the first detections of the 88 {mu}m [O III] line from galaxies in the early universe, detecting the line from the lensed active galactic nucleus (AGN)/starburst composite systems APM 08279+5255 at z = 3.911 and SMM J02399-0136 at z = 2.8076. The line is exceptionally bright from both systems, with apparent (lensed) luminosities {approx}10{sup 11} L {sub sun}. For APM 08279, the [O III] line flux can be modeled in a star formation paradigm, with the stellar radiation field dominated by stars with effective temperatures, T {sub eff} > 36,000 K, similar to the starburst found in M82. The model implies {approx}35% of the total far-IR luminosity of the system is generated by the starburst, with the remainder arising from dust heated by the AGN. The 88 {mu}m line can also be generated in the narrow-line region of the AGN if gas densities are around a few 1000 cm{sup -3}. For SMM J02399, the [O III] line likely arises from H II regions formed by hot (T {sub eff} > 40,000 K) young stars in a massive starburst that dominates the far-IR luminosity of the system. The present work demonstrates the utility of the [O III] line for characterizing starbursts and AGN within galaxies in the early universe. These are the first detections of this astrophysically important line from galaxies beyond a redshift of 0.05.

WISE TF: A MID-INFRARED, 3.4 {mu}m EXTENSION OF THE TULLY-FISHER RELATION USING WISE PHOTOMETRY  

SciTech Connect (OSTI)

We present a mid-infrared Tully-Fisher (TF) relation using photometry from the 3.4 {mu}m W1 band of the Wide-field Infrared Survey Explorer (WISE) satellite. The WISE TF relation is formed from 568 galaxies taken from the all-sky 2MASS Tully-Fisher (2MTF) galaxy catalog, spanning a range of environments including field, group, and cluster galaxies. This constitutes the largest mid-infrared TF relation constructed to date. After applying a number of corrections to galaxy magnitudes and line widths, we measure a master TF relation given by M{sub corr} = -22.24 - 10.05[log (W{sub corr}) - 2.5], with an average dispersion of {sigma}{sub WISE} = 0.686 mag. There is some tension between WISE TF and a preliminary 3.6 {mu}m relation, which has a shallower slope and almost no intrinsic dispersion. However, our results agree well with a more recent relation constructed from a large sample of cluster galaxies. We additionally compare WISE TF to the near-infrared 2MTF template relations, finding a good agreement between the TF parameters and total dispersions of WISE TF and the 2MTF K-band template. This fact, coupled with typical galaxy colors of (K - W1) {approx} 0, suggests that these two bands are tracing similar stellar populations, including the older, centrally-located stars in the galactic bulge which can (for galaxies with a prominent bulge) dominate the light profile.

Surface diffusion coefficient of Au atoms on single layer graphene grown on Cu  

SciTech Connect (OSTI)

A 5?nm thick Au film was deposited on single layer graphene sheets grown on Cu. By thermal processes, the dewetting phenomenon of the Au film on the graphene was induced so to form Au nanoparticles. The mean radius, surface-to-surface distance, and surface density evolution of the nanoparticles on the graphene sheets as a function of the annealing temperature were quantified by scanning electron microscopy analyses. These quantitative data were analyzed within the classical mean-field nucleation theory so to obtain the temperature-dependent Au atoms surface diffusion coefficient on graphene: D{sub S}(T)=[(8.2±0.6)×10{sup ?8}]exp[?(0.31±0.02(eV)/(at) )/kT]?cm{sup 2}/s.

Comparison Between Simulated And Experimental Au-ion Profiles Implanted in nanocrystalline ceria  

SciTech Connect (OSTI)

Radiation response of nanocrystalline ceria films deposited on a silicon substrate was investigated under a 3-MeV Au-ion irradiation at 300 K. A uniform grain growth cross the ceria films is observed and effective densification of the ceria thin films occurs during irradiation. The Au ion profiling was measured by secondary ion mass spectrometry (SIMS) and compared to the Au ion distribution predicted by the Stopping and Range of Ions in Solids (SRIM) code. It is observed that the Au-ion penetration depth is underestimated in comparison with the SIMS measurements. An overestimation of the electronic stopping power for heavy incident ions in the SRIM program may account for the discrepancies between the calculations and the SIMS experimental results. This work presents an approach to compensate the overestimation of the electronic stopping powers in the SRIM program by adjusting the nanocrystalline ceria target density to better predict the ion implantation profile.

Systematic Study of Azimuthal Anisotropy in Cu$+$Cu and Au$+$Au Collisions at $\\sqrt{s_{_{NN}}} = 62.4$ and 200~GeV  

E-Print Network [OSTI]

We have studied the dependence of azimuthal anisotropy $v_2$ for inclusive and identified charged hadrons in Au$+$Au and Cu$+$Cu collisions on collision energy, species, and centrality. The values of $v_2$ as a function of transverse momentum $p_T$ and centrality in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$=200~GeV and 62.4~GeV are the same within uncertainties. However, in Cu$+$Cu collisions we observe a decrease in $v_2$ values as the collision energy is reduced from 200 to 62.4~GeV. The decrease is larger in the more peripheral collisions. By examining both Au$+$Au and Cu$+$Cu collisions we find that $v_2$ depends both on eccentricity and the number of participants, $N_{\\rm part}$. We observe that $v_2$ divided by eccentricity ($\\varepsilon$) monotonically increases with $N_{\\rm part}$ and scales as ${N_{\\rm part}^{1/3}}$. The Cu$+$Cu data at 62.4 GeV falls below the other scaled $v_{2}$ data. For identified hadrons, $v_2$ divided by the number of constituent quarks $n_q$ is independent of hadron species as a function of transverse kinetic energy $KE_T=m_T-m$ between $0.1

Particle production at high baryon density in central Au+Au reactions at 11.6A GeV/c  

Science Journals Connector (OSTI)

Semi-inclusive proton and pion distributions from central Au+Au reactions at 11.6A GeV/c have been measured. The proton rapidity distribution shows significantly increased stopping compared to lighter systems, providing strong evidence for the formation of a state of matter with baryon density substantially greater than normal nuclear matter. Unlike reactions at this energy induced by lighter heavy ions, at low mt-m0 the proton invariant spectra deviate from a single exponential shape and become flatter, while ?- spectra are found to rise faster than the ?+ spectra.

Pion Interferometry in Au+Au and Cu+Cu Collisions at sqrt sNN = 62.4 and 200 GeV  

SciTech Connect (OSTI)

We present a systematic analysis of two-pion interferometry in Au+Au collisions at {radical}sNN = 62.4 GeV and Cu+Cu collisions at {radical}sNN = 62.4 and 200 GeV using the STAR detector at RHIC. The multiplicity and transverse momentum dependences of the extracted correlation lengths (radii) are studied. The scaling with charged particle multiplicity of the apparent system volume at final interaction is studied for the RHIC energy domain. The multiplicity scaling of the measured correlation radii is found to be independent of colliding system and collision energy.

Information about compressed high density nuclear matter can be obtained by studying collective flow exhibited by particles emitted in heavy ion induced reactions. Charged particles have been measured in 4{pi} coverage for {sup 197}Au + {sup 197}Au collisions at E/A = 100, 250 and 400 MeV using the Miniball/Wall, the Catania Silicon-CsI array and the Aladin Spectrometer. Collective observables such as transverse sideward flow, radial flow and squeezeout will be discussed and the measured values will be compared to transport models.

Interfacial oxygen under TiO{sub 2} supported Au clusters revealed by a genetic algorithm search  

SciTech Connect (OSTI)

We present a density functional theory study of the oxidation of 1D periodic rods supported along the [001] direction on the rutile TiO{sub 2}(110) surface. The study shows evidence for an oxidation of the interface between the supported Au and the TiO{sub 2} crystal. The added O atoms adsorb at the 5f-Ti atoms in the through under the Au rod and are stabilized by charge transfer from the nearest Au atoms. Despite an extensive search, we find no low energy barrier pathways for CO oxidation involving CO adsorbed on Au and O at the perimeter of the Au/TiO{sub 2} interface. This is in part attributed the weak adsorption of CO on cationic Au at the perimeter.

Effect of Alumina and Titania on the Oxidation of CO over Au Nanoparticles Evaluted by 13C Isotopic Transient Analysis  

SciTech Connect (OSTI)

Titania- and alumina-supported Au nanoparticles were synthesized by a deposition-precipitation method and subsequent thermal treatment in He. X-ray absorption spectroscopy at the Au-L{sub III} edge revealed that the as-prepared Au/TiO{sub 2} sample contained cationic Au that was reduced to a predominately metallic state after treatment in He at 623 K. Scanning transmission electron microscopy showed the Au to be highly dispersed over both the metal oxides, with an average particle size of 3.3 nm for Au/TiO{sub 2} and 2.5 nm for Au/Al{sub 2}O{sub 3}. The global rate, apparent activation energy, and orders of reaction with respect to CO and O{sub 2} of CO oxidation were different for the two metal oxide-supported samples. Steady-state isotopic transient kinetic analysis was used to explore the intrinsic turnover frequency (TOF{sub intr}) and coverage of active carbon-containing intermediates ({theta}{sub COx}) that led to carbon dioxide during CO oxidation. After correcting for CO{sub 2} readsorption, the TOF{sub intr} was found to be independent of temperature, approximately 3.4 s{sup -1} for Au/TiO{sub 2} (261-303 K) and 2.1 s{sup -1} for Au/Al{sub 2}O{sub 3} (272-343 K). At 293 K, the coverage of active carbon-containing intermediates was greater over Au/TiO{sub 2} than over Au/Al{sub 2}O{sub 3}. The higher coverage of species-forming product on Au/TiO{sub 2} is attributed to the greater availability of active surface oxygen on a titania catalyst compared with an alumina catalyst.

Selection Tests of MnZn and NiZn Ferrites for Mu2e 300 kHz and 5.1 MHz AC Dipoles  

SciTech Connect (OSTI)

Mu2e, a charged lepton flavor violation (CLFV) experiment is planned to start at Fermilab late in this decade. The proposed experiment will search for neutrinoless muon to electron conversions with unprecedented sensitivity, better than 6 x 10{sup -17 }at 90% CL. To achieve this sensitivity the incoming proton beam must be highly suppressed during the window for detecting the muon decays. The current proposal for beam extinction is based on a collimator design with two dipoles running at {approx}300 kHz and 5.1 MHz and synchronized to the proton bunch spacing. The appropriate choice of ferrite material for the magnet yoke is a critical step in the overall design of the dipoles and their reliable operation at such high frequencies over the life of the experiment. This choice, based on a series of the thermal and magnetic measurements of the ferrite samples, is discussed in the paper. Additionally, the first results from the testing at 300 kHz of a prototype AC dipole are presented.

Temperature-dependent collision-broadening parameters of H[sub 2]O lines in the 1. 4-[mu]m region using diode laser absorption spectroscopy  

SciTech Connect (OSTI)

Radiative properties of water vapor in the infrared spectrum are important in a variety of applications, including atmospheric sounding experiments, radiative sensing of combustion processes, and optical diagnostics for gasdynamic and aerodynamic studies. Here, spectrally resolved measurements of water vapor absorption spectra near 1.4 [mu]m have been performed with a tunable, distributed-feedback InGaAsP diode laser. A lineshape analysis was used to infer the collision-broadening coefficient of 11 rovibrational transitions in the [nu] + [nu][sub 3] and 2[nu][sub 1] vibration bands perturbed separately by N[sub 2], O[sub 2], CO[sub 2], and H[sub 2]. The temperature dependence of the broadening coefficients was determined using a temperature-controlled static cell and a pressure-driven shock tube over the range 300--1,200 K. The measured coefficients are in good agreement with the previous calculations of Delaye. Also, agreement is found between prior experimental data, obtained for the same rotational transitions but different vibration bands, and the results.

Measurements of line strengths in the HO sub 2. nu. sub 1 overtone band at 1. 5. mu. m using an InGaAsP laser  

SciTech Connect (OSTI)

The hydroperoxyl radical, HO{sub 2}, is a pivotal atmospheric species, being closely coupled to OH, the most important oxidant in both tropospheric and stratospheric chemistry. The authors report the first observation of resolved rotational-vibrational overtone (2{nu}{sub 1}) absorptions of the hydroperoxyl radical (HO{sub 2}) in the 1.5-{mu}m region, using two-tone frequency modulation spectroscopy (TTFMS) with an InGaAsP laser diode and White-cell optics. Photolysis of Cl{sub 2}/H{sub 2}O{sub 2} mixtures was used to produce the HO{sub 2}, and the concentration was determined by modulated-photolysis UV absorption spectroscopy. The line center adsorption cross sections for the strongest lines ranged between 1.3 {times} 10{sup {minus}20} and 10 {times} 10{sup {minus}20} cm{sup 2} molecule{sup {minus}1} under Doppler-limited conditions. For the strongest line this corresponds to an integrated line strength S of 1.6 {times} 10{sup {minus}21} cm{sup 2} molecule{sup {minus}1} cm{sup {minus}1}, a line strength of the same order of magnitude as lines previously observed in the relatively weak {nu}{sub 1} fundamental.

SeD Radical: A probe for measurement of time variation of Fine Structure Constant($\\alpha$) and Proton to Electron Mass Ratio($\\mu$)  

E-Print Network [OSTI]

Based on the spectroscopic constants derived from highly accurate potential energy surfaces, the SeD radical is identified as a spectroscopic probe for measuring spatial and temporal variation of fundamental physical constants such as the fine-structure constant (denoted as $\\alpha=\\frac{e^2}{\\hbar c}$) and the proton-to-electron mass ratio (denoted as $\\mu=\\frac{m_p}{m_e}$). The ground state of SeD ($X^2\\Pi$), due to spin-orbit coupling, splits into two fine structure multiplets $^2\\Pi_{\\frac{3}{2}}$ and $^2\\Pi_{\\frac{1}{2}}$. The potential energy surfaces of these spin-orbit components are derived from a state of the art electronic structure method, MRCI+Q inclusive of scalar relativistic effects with the spin-orbit effects accounted through the Breit-Pauli operator. The relevant spectroscopic data are evaluated using Murrel-Sorbie fit to the potential energy surfaces. The spin-orbit splitting($\\omega_f$) between the two multiplets is similar in magnitude with the harmonic frequency ($\\omega_e$) of the diat...

On the Dissociation of Molecular Hydrogen by Au Supported on Transition Metal Carbides: Choice of the Most Active Support  

SciTech Connect (OSTI)

A systematic density functional study of the adsorption and dissociation of H{sub 2} on the clean (001) surface of various transition metal carbides (TMCs; TM = Ti, Zr, V, Mo) and on Au{sub 4} nanoclusters supported on these TMCs is presented. It is found that the H{sub 2} dissociation on the bare clean TMCs strongly depends on the chemical nature of the support. Thus, the H{sub 2} molecule interacts rather strongly with TiC(001) and ZrC(001) but very weakly with VC(001) and {delta}-MoC(001). For the supported Au{sub 4} cluster, two different types of molecular mechanisms are found. For Au{sub 4}/TiC(001) and Au{sub 4}/ZrC(001), H{sub 2} dissociation leads to a H atom directly interacting with the Au{sub 4} cluster while the second H atom is transferred to the support. In contrast, for Au{sub 4}/VC(001) and Au{sub 4}/{delta}-MoC(001), both H atoms interact with the Au{sub 4} cluster. Overall, the present study suggests that, among the systems studied, Au/ZrC is the best substrate for H{sub 2} dissociation.

Detailed characterization of Mo/Au TES microcalorimeters  

Science Journals Connector (OSTI)

We are optimizing Mo/Au transition-edge-sensor (TES) calorimeters to meet the specifications of NASA’s Constellation-X mission. Our calorimeters have already demonstrated very good energy resolution of X rays (2.4 eV at 1.5 keV). We wish to further improve the energy resolution by reducing excess noise in the calorimeters. Development of a detailed model and understanding of the noise is instrumental to reaching this goal. Towards that end we employ a linear model that describes the response of a calorimeter to signal and various sources of noise. The model is based on detailed measurements of the parameters that affect the calorimeter’s performance such as current-voltage characteristics of the TES thermal conductance of our silicon-nitride membranes and inductance in the electronic circuit used to bias the TES. We determine the sharpness of the superconducting phase transition by fitting the model to the measured responsivity of the calorimeter. The model relates sources of noise such as phonon noise Johnson noise and hypothetical sources of excess noise to measurements of noise in the TES. Based on this analysis we find that the excess noise is consistent with frequency-independent voltage noise in the TES

Probing the equation of state in Au+Au at 11 GeV/nucleon with (3+1)-dimensional hydrodynamics  

SciTech Connect (OSTI)

The effect of (i) the phase transition between a quark gluon plasma (QGP) and a hadron gas and (ii) the number of resonance degrees of freedom in the hadronic phase on the single inclusive distributions of 16 different types of produced hadrons for Au+Au collisions at the Brookhaven Alternating Gradient Synchroton (AGS) energies is studied. We have used an exact numerical solution of the relativistic hydrodynamical equations {ital without free parameters} which, because of its (3+1)-dimensional character, constitutes a considerable improvement over the classical Landau solution. We assume chemical equilibration and we use two different equations of state (EOS): one describing a phase transition from QGP to the hadronic phase and two versions of a purely hadronic EOS; we find that the first one gives an overall better description of the Au+Au experimental data at AGS energies. We reproduce and analyze measured meson and proton spectra and also make predictions for antiprotons, deltas, antideltas, and hyperons. The low m{sub t} enhancement in {pi}{sup {minus}} spectra is explained by baryon number conservation and strangeness equilibration. The sensitivity of various production channels to the EOS is analyzed. {copyright} {ital 1997} {ital The American Physical Society}

Thermal stability and adhesion of low-emissivity electroplated Au coatings.  

SciTech Connect (OSTI)

We are developing a low-emissivity thermal management coating system to minimize radiative heat losses under a high-vacuum environment. Good adhesion, low outgassing, and good thermal stability of the coating material are essential elements for a long-life, reliable thermal management device. The system of electroplated Au coating on the adhesion-enhancing Wood's Ni strike and 304L substrate was selected due to its low emissivity and low surface chemical reactivity. The physical and chemical properties, interface bonding, thermal aging, and compatibility of the above Au/Ni/304L system were examined extensively. The study shows that the as-plated electroplated Au and Ni samples contain submicron columnar grains, stringers of nanopores, and/or H{sub 2} gas bubbles, as expected. The grain structure of Au and Ni are thermally stable up to 250 C for 63 days. The interface bonding is strong, which can be attributed to good mechanical locking among the Au, the 304L, and the porous Ni strike. However, thermal instability of the nanopore structure (i.e., pore coalescence and coarsening due to vacancy and/or entrapped gaseous phase diffusion) and Ni diffusion were observed. In addition, the study also found that prebaking 304L in the furnace at {ge} 1 x 10{sup -4} Torr promotes surface Cr-oxides on the 304L surface, which reduces the effectiveness of the intended H-removal. The extent of the pore coalescence and coarsening and their effect on the long-term system integrity and outgassing are yet to be understood. Mitigating system outgassing and improving Au adhesion require a further understanding of the process-structure-system performance relationships within the electroplated Au/Ni/304L system.

Photocatalytic H2 production from ethanol over Au/TiO2 and Ag/TiO2  

Science Journals Connector (OSTI)

This paper compares the photocatalytic activities of Au/TiO2 (Au loadings 0-4 wt.%) and Ag/TiO2 photocatalysts (Ag loadings 0-4 wt.%) for H2 production from ethanol-water mixtures under UV irradiation. Au and Ag nanoparticles were deposited on commercially available Degussa P25 TiO2 (85% anatase, 15% rutile) using deposition-precipitation and liquid impregnation methods, respectively. TEM analyses showed the average noble metal nanoparticle size to be ~5 nm for the Au/TiO2 photocatalysts and ~3 nm for the Ag/TiO2 photocatalysts. Au/TiO2 photocatalysts showed a strong localised surface plasmon resonance (LSPR) at 570 nm characteristic for nanocrystalline Au. Complementary XRD studies confirmed that Au and Ag nanoparticles were present in metallic form. Photoluminescence measurements revealed that Au and Ag nanoparticles effectively suppress electron-hole recombination in TiO2, thereby enhancing the photocatalytic activity of TiO2 for hydrogen production. Au/TiO2 photocatalysts were far more active for H2 production from ethanol-water mixtures than Ag/TiO2 photocatalysts. A 1 wt.% Au/TiO2 photocatalyst yielded the highest H2 production rate (34 mmol g?1 h?1). Amongst the Ag/TiO2 photocatalysts, the 2 wt.% Ag/TiO2 sample was the most active (3.7 mmol g?1 h?1). Results are rationalised in terms of differences in the electronic properties of supported Au and Ag nanoparticles, with the former being near ideal for H2 production.

Super-Stable, Highly Monodisperse Plasmonic Nanocrystals with 500 Gold Atoms: Au~500(SR)~120  

SciTech Connect (OSTI)

Determining the composition of plasmonic nanoparticles is challenging due to a deficiency in tools capable of accurately evaluating the number of atoms. Mass spectrometry plays a significant role in determining nanoparticle composition at the atomic level. Significant progress has been made in understanding ultra-small gold nanoparticles, like Au25(SR)18 and Au38(SR)24, with a Au core diameter of 0.97 and 1.3 nm, respectively. However, progress in small plasmonic nanoparticles (2 - 5 nm) is currently challenging, due in part to limitations in synthesizing monodisperse nanoparticles. Here, we report a plasmonic nanocrystal that is highly monodisperse, with an unprecedented variation of less than 20 gold atoms. The composition of the super-stable plasmonic nanocrystals at 115 kDa was determined to contain Au500 10SR120 3. The Au~500 system, named Faraduarate-500, is the largest size to be characterized using high resolution ESI mass spectrometry. Atomic pair distribution function (PDF) data shows that the local atomic structure is consistent with a face-centered cubic (fcc) or Marks decahedral arrangement. High resolution scanning transmission electron microscopy images show that the diameter is 2.4 0.1 nm. The radius of gyration measured by small angle X-ray scattering (SAXS), is 1.05 0.05 nm, and the size and the shape of SAXS molecular envelope are in agreement with TEM and PDF measurements.

De l’humanisme au posthumanisme : le destin du corps  

Science Journals Connector (OSTI)

Résumé L’humanisme aurait-il fait son temps ? Comment vivre au milieu des autres quand l’humain devient une sorte de résultante entre nature et biotechnologies ? Ne faut-il pas abandonner notre nature si fragile pour advenir à une posture inaltérable, voire dématérialisée ? Le corps semble bien être la prison de l’âme pour certains contemporains qui envisagent donc sa désintégration. Notre propos tente de montrer combien cette tentative de fusion dans un grand tout, renvoie à une profonde dépression de l’être ou un refus conscient ou non de se réaliser, voire d’assumer sa condition. Le monde transhumain est un monde où les nanorobots détruiront les agents pathogènes, les erreurs ADN voire élimineront les toxines. Ainsi, l’homme pourra se décliner sous une nouvelle version v 2.0. Est-ce une fin en soi ? Que dire alors à celles et ceux qui semblent aspirés par cette dynamique si ce n’est que c’est peut être la fragilité de la naissance, la beauté du développement et de la vie qui est le cœur de notre humanité ? Summary Is it the end of Humanism? How can we actually live together, when human want to be a patchwork mixing nature and biotechnologies? Many people seem to give up their weakness and hope in a new unaffected situation. As body seems to be jail of soul, people want to split it. Our purpose tries to explain the reasons of this paradoxal course. Transhumanism is related to depression and conscious or unconscious refusal to assume their conditions. How can we help people who consider this evolution as an end as itself? What can we tell to them, if the fragility of the birth and the beauty of development are the core of the human being?

Does H2O improve the catalytic activity of Au1-4/MgO towards CO oxidation?  

E-Print Network [OSTI]

The present density functional theory study addresses the question whether the presence of H2O influences the catalytic activity of small gold clusters, Au1-4/MgO(100), towards the oxidation of carbon monoxide. To this end, we studied the (co-)adsorption of H2O and CO/O2 on these gold clusters. The ground state structures in the presence of all three molecular species, that we found, are Au1O2/MgO and Au2-4CO/MgO with H2O adsorbed on the surface in the proximity of the clusters-molecule complex. In this configuration the catalytic activity of Au1-4/MgO is indifferent to the presence of H2O. We also found that a stable, highly activated hydroperoxyl-hydroxyl complex, O2H\\dot\\dot OH, can be formed on Au1,3/MgO. For the catalytic active system Au8/MgO, it has been predicted that this complex opens an alternative catalytic reaction pathway towards CO oxidation. Our results suggest that this water mediated catalytic cycle is unlikely to occur on Au1,3/MgO. In the case of Au1/MgO the cycle is interrupted by the dis...

Transmission electron microscopy and Monte Carlo simulations of ordering in Au-Cu clusters produced in a laser vaporization source  

Science Journals Connector (OSTI)

Au-Cu bimetallic alloy clusters are produced in a laser vaporization source starting from Au-Cu alloy targets with different stoichiometric compositions. The clusters are deposited on two different substrates—amorphous carbon and crystalline MgO—and are characterized by electron diffraction and high-resolution electron microscopy. The experiments show that the overall chemical composition in the clusters is the same as the chemical composition of the target material; but the crystal structure of the Au-Cu alloy clusters differs from their known bulk crystal structure. Electron microscopy experiments provide evidence that no chemical ordering exists between Au and Cu atoms and that the clusters are solid solutions. Monte Carlo simulations using the second moment tight-binding approximation, however, predict Cu3Au clusters ordered in the core but with a disordered mantle. The possible origins of the differences between experiment and Monte Carlo simulations are discussed.

This paper reports the fabrication of a flip-chip InGaAsP-InAlAs superlattice avalanche photodiode using gas source molecular beam epitaxy. The incident light reaches the InGaAs photoabsorption layer through the InP substrate and an InGaAsP-InAlAs superlattice multiplication region which are transparent for wavelengths of 1.55 and 1.3 [mu]m. The light reflection by the electrode enables the absorption layer to be as thin as 0.8 [mu]m without significantly reducing the quantum efficiency. A maximum bandwidth of 17 GHz was obtained at a low multiplication factor because of the transit time through the absorption layer is reduced.

Ag and Au atoms intercalated in bilayer heterostructures of transition metal dichalcogenides and graphene  

SciTech Connect (OSTI)

The diffusive motion of metal nanoparticles Au and Ag on monolayer and between bilayer heterostructures of transition metal dichalcogenides and graphene are investigated in the framework of density functional theory. We found that the minimum energy barriers for diffusion and the possibility of cluster formation depend strongly on both the type of nanoparticle and the type of monolayers and bilayers. Moreover, the tendency to form clusters of Ag and Au can be tuned by creating various bilayers. Tunability of the diffusion characteristics of adatoms in van der Waals heterostructures holds promise for controllable growth of nanostructures.

PdAgAu alloy with high resistance to corrosion by H{sub 2}S  

SciTech Connect (OSTI)

PdAgAu alloy films were prepared on porous stainless steel supports by sequential electroless deposition. Two specific compositions, Pd{sub 83}Ag{sub 2}Au{sub 15} and Pd{sub 74}Ag{sub 14}Au{sub 12}, were studied for their sulfur tolerance. The alloys and a reference Pd foil were exposed to 1000 H{sub 2}S/H{sub 2} at 623 K for periods of 3 and 30 hours. The microstructure, morphology and bulk composition of both nonexposed and H{sub 2}S-exposed samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). XRD and SEM analysis revealed time-dependent growth of a bulk Pd{sub 4}S phase on the Pd foil during H{sub 2}S exposure. In contrast, the PdAgAu ternary alloys displayed the same FCC structure before and after H{sub 2}S exposure. In agreement with the XRD and SEM results, sulfur was not detected in the bulk of either ternary alloy samples by EDS, even after 30 hours of H{sub 2}S exposure. X-ray photoelectron spectroscopy (XPS) depth profiles were acquired for both PdAgAu alloys after 3 and 30 hours of exposure to characterize sulfur contamination near their surfaces. Very low S 2p and S 2s XPS signals were observed at the top-surfaces of the PdAgAu alloys, and those signals disappeared before the etch depth reached ~ 10 nm, even for samples exposed to H{sub 2}S for 30 hours. The depth profile analyses also revealed silver and gold segregation to the surface of the alloys; preferential location of Au on the alloys surface may be related to their resistance to bulk sulfide formation. In preliminary tests, a PdAgAu alloy membrane displayed higher initial H{sub 2} permeability than a similarly prepared pure Pd sample and, consistent with resistance to bulk sulfide formation, lower permeability loss in H{sub 2}S than pure Pd.

Rapidity and centrality dependence of proton and anti-proton production from 197Au+197Au collisions at {radical}(s{sub NN}) = 130 GeV  

SciTech Connect (OSTI)

We report on the rapidity and centrality dependence of proton and anti-proton transverse mass distributions from {sup 197}Au + {sup 197}Au collisions at {radical}s{sub NN} = 130 GeV as measured by the STAR experiment at RHIC. Our results are from the rapidity and transverse momentum range of |y| < 0.5 and 0.35 < p{sub t} < 1.00 GeV/c. For both protons and anti-protons, transverse mass distributions become more convex from peripheral to central collisions demonstrating characteristics of collective expansion. The measured rapidity distributions and the mean transverse momenta versus rapidity are flat within |y| < 0.5. Comparisons of our data with results from model calculations indicate that in order to obtain a consistent picture of the proton(anti-proton) yields and transverse mass distributions the possibility of pre-hadronic collective expansion may have to be taken into account.

Hadronization geometry and charge-dependent two-particlecorrelation on momentum subspace (eta, phi) in Au-Au collisions atsqrt(sNN) = 130 GeV  

SciTech Connect (OSTI)

We present the first measurements of charge-dependent two-particle correlations on momentum-space difference variables {eta}{sub 1}-{eta}{sub 2} (pseudorapidity) and {phi}{sub 1}-{phi}{sub 2} (azimuth) for primary charged hadrons with transverse momentum 0.15 {le} p{sub t} {le} 2 GeV/c and |{eta}| {le} 1.3 from Au-Au collisions at {radical}s{sub NN} = 130 GeV. We observe correlation structures not predicted by theory but consistent with evolution of hadron emission geometry with increasing centrality from one-dimensional fragmentation of color strings to higher-dimensional fragmentation of a hadron-opaque bulk medium.

Particle-type dependence of azimuthal anisotropy and nuclearmodification of particle production in Au+Au collisions at sNN = 200GeV  

SciTech Connect (OSTI)

We present STAR measurements of the azimuthal anisotropy parameter v{sub 2} and the binary-collision scaled centrality ratio R{sub CP} for kaons and lambdas ({Lambda} + {bar {Lambda}}) at mid-rapidity in Au+Au collisions at {radical}s{sub NN} = 200 GeV. In combination, the v{sub 2} and R{sub CP} particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish p{sub T} {approx} 5 GeV/c as the value where the centrality dependent baryon enhancement ends. The K{sub S}{sup 0} and {Lambda} + {bar {Lambda}} v{sub 2} values are consistent with expectations of constituent-quark-number scaling from models of hadron formation by parton coalescence or recombination.

Femtoscopy in PHENIX: Evidence for a Long Range Structure in the Pion Emission Source in Au+Au Collisions at RHIC  

SciTech Connect (OSTI)

The PHENIX experiment has acquired {approx}1 billion minimum bias Au+Au events at {radical}(s) = 200AGeV during the year 2004. This high statistics data set, coupled with a state-of-the-art analysis technique, allows for the extraction of 3D emission sources for various particle types. These 3D sources lend fresh insight into the nature of a long-range source previously reported by PHENIX. The new results indicate an anisotropic pion emission source in the pair center of mass system (PCMS) having an extended space-time extent in the outward direction. The two-proton emission source from the same data set is essentially isotropic in the PCMS. These results provide information on the evolution dynamics of the high energy density nuclear matter created at RHIC.

Excited-state OH Mainline Masers in AU Geminorum and NML Cygni  

E-Print Network [OSTI]

Excited-state OH maser emission has previously been reported in the circumstellar envelopes of only two evolved stars: the Mira star AU Geminorum and the hypergiant NML Cygni. We present Very Large Array (VLA) observations of the 1665, 1667, and excited-state 4750 MHz mainline OH transitions in AU Gem and Expanded Very Large Array (EVLA) observations of the excited-state 6030 and 6035 MHz OH mainline transitions in NML Cyg. We detect masers in both mainline transitions in AU Gem but no excited-state emission in either star. We conclude that the excited-state OH emission in AU Gem is either a transient phenomenon (such as for NML Cyg outlined below), or possibly an artifact in the data, and that the excited state OH emission in NML Cyg was generated by an episode of enhanced shock between the stellar mass-loss and an outflow of the Cyg OB2 association. With these single exceptions, it therefore appears that excited-state OH emission indeed should not be predicted nor observable in evolved stars as part of their normal structure or evolution.

High-resolution photoemission spectroscopy study of clean and Au-nanowire-decorated Si(5 5 12) surfaces  

Science Journals Connector (OSTI)

We have examined the Si 2p photoemission line shape of the clean Si(5 5 12)2×1 surface in detail and have investigated the evolution of the Au-induced nanowires on this surface at different temperatures with low-energy-electron diffraction and photoemission spectroscopy. The Si 2p spectra from the clean 2×1 surface exhibit very complex line shapes composed at least of five different surface-related components. Possible origins of the most distinct surface component with a surface core-level shift of -0.62 eV are discussed within the three different structure models proposed so far. Upon Au deposition, the intensity of that particular surface component was largely reduced indicating that the Au adsorbates interact dominantly with the specific Si surface atoms related. With an annealing above 500°C after Au deposition of 0.2 ML, the surface drastically changes into a metallic phase, as shown clearly in the valence band photoemission spectra, along with the gradual formation of the (337)×2 facets observed in LEED. In this transition, a new Au 4f component appears while the Si 2p core-level spectra keep alike. This indicates that the surface metallization involves the rearrangement of Au adsorbates, possibly the formation of new Au chains on the surface.

Insights into the reaction mechanism for 5-hydroxymethylfurfural oxidation to FDCA on bimetallic Pd–Au nanoparticles  

Science Journals Connector (OSTI)

Abstract This work deals with the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) in water using supported Pd–Au nanoparticles. The active phase composition was shown to be crucial for FDCA formation. Indeed, both Au and Pd monometallic nanoparticles formed 5-hydroxymethyl-2-furancarboxylic acid (HMFCA) under the studied conditions; however, with Pd nanoparticles HMFCA was not further transformed, while Au and bimetallic Pd–Au systems both catalysed its oxidation to FDCA. The thermal treatment of Pd–Au catalysts considerably modified their catalytic activity, because Pd atoms migrated and concentrated onto the outer part of bimetallic nanoparticles. The resulting active phase morphology showed a different reaction path for FDCA formation compared to the untreated catalyst, with an important contribution of the Cannizzaro reaction. PVP-protected Pd–Au nanoparticles with different structures (either alloy or core-shell morphology) were synthesized and their reactivity tested in order to confirm the presence of different mechanisms for HMF oxidation, depending on whether the active phase preferentially exposes either Pd or Au atoms.

Structural and electronic properties of Au{sub n?x}Pt{sub x} (n = 2–14; x ? n) clusters: The density functional theory investigation  

SciTech Connect (OSTI)

The structural evolutions and electronic properties of bimetallic Au{sub n–x}Pt{sub x} (n = 2–14; x ? n) clusters are investigated by using the density functional theory (DFT) with the generalized gradient approximation (GGA). The monatomic doping Au{sub n–1}Pt clusters are emphasized and compared with the corresponding pristine Au{sub n} clusters. The results reveal that the planar configurations are favored for both Au{sub n–1}Pt and Au{sub n} clusters with size up to n = 13, and the former often employ the substitution patterns based on the structures of the latter. The most stable clusters are Au{sub 6} and Au{sub 6}Pt, which adopt regular planar triangle (D{sub 3h}) and hexagon-ring (D{sub 6h}) structures and can be regarded as the preferential building units in designing large clusters. For Pt-rich bimetallic clusters, their structures can be obtained from the substitution of Pt atoms by Au atoms from the Pt{sub n} structures, where Pt atoms assemble together and occupy the center yet Au atoms prefer the apex positions showing a segregation effect. With respect to pristine Au clusters, Au{sub n}Pt clusters exhibit somewhat weaker and less pronounced odd-even oscillations in the highest occupied and lowest unoccupied molecular-orbital gaps (HOMO-LUMO gap), electron affinity (EA), and ionization potential (IP) due to the partially released electron pairing effect. The analyses of electronic structure indicate that Pt atoms in AuPt clusters would delocalize their one 6s and one 5d electrons to contribute the electronic shell closure. The sp-d hybridizations as well as the d-d interactions between the host Au and dopant Pt atoms result in the enhanced stabilities of AuPt clusters.

MULTI-WAVELENGTH STUDY OF A COMPLETE IRAC 3.6 {mu}m SELECTED GALAXY SAMPLE: A FAIR CENSUS OF RED AND BLUE POPULATIONS AT REDSHIFTS 0.4-1.2  

SciTech Connect (OSTI)

We present a multi-wavelength study of a 3.6 {mu}m selected galaxy sample in the Extended Groth Strip (EGS). The sample is complete for galaxies with stellar mass >10{sup 9.5} M{sub Sun} and redshift 0.4 < z < 1.2. In this redshift range, the Infrared Array Camera 3.6 {mu}m band measures the rest-frame near-infrared band, permitting nearly unbiased selection with respect to both quiescent and star-forming galaxies. The numerous spectroscopic redshifts available in the EGS are used to train an artificial neural network to estimate photometric redshifts. The distribution of photometric redshift errors is Gaussian with standard deviation {approx}0.025(1 + z), and the fraction of redshift failures (>3{sigma} errors) is about 3.5%. A new method of validation based on pair statistics confirms the estimate of standard deviation even for galaxies lacking spectroscopic redshifts. Basic galaxy properties measured include rest-frame U - B colors, B- and K-band absolute magnitudes, and stellar masses. We divide the sample into quiescent and star-forming galaxies according to their rest-frame U - B colors and 24-3.6 {mu}m flux density ratios and derive rest K-band luminosity functions and stellar mass functions for quiescent, star-forming, and all galaxies. The results show that massive, quiescent galaxies were in place by z Almost-Equal-To 1, but lower mass galaxies generally ceased their star formation at later epochs.

Comparative study of the alloying effect on the initial oxidation of Cu-Au(100) and Cu-Pt(100)  

SciTech Connect (OSTI)

Using in situ transmission electron microscopy, we show that the oxidation of the Cu-Au(100) results in the formation of Cu{sub 2}O islands that deeply embed into the Cu-Au substrate while the oxidation of the Cu-Pt(100) leads to the formation of Cu{sub 2}O islands that highly protrude above the Cu-Pt substrate. Their difference is attributed to the different mobilities of Pt and Au in the Cu base alloys for which the sluggish mobility of Pt in Cu results in trapped Pt atoms at the oxide/alloy interface while the faster mobility of Au in Cu leads to enhanced rehomogenization of the alloy composition.

We present experimental results for laser-induced Au nanoparticle (NP) embedded in a HfO{sub 2} high-k dielectric matrix. Cross-sectional transmission electron microscopy images showed that the Au NPs of 8 nm in diameter were clearly embedded in HfO{sub 2} matrix. Capacitance-voltage measurements of Pt/HfO{sub 2}/Au NPs/HfO{sub 2} on p-type Si substrate reliably exhibited metal-oxide-semiconductor behavior with a large flatband shift of 4.7 V. In addition, the charge retention time at room temperature was found to exceed 10{sup 5} h. This longer time was attributed to the higher electron barrier height via high work function of the Au NP.

Structure, stability, and electronic property of carbon-doped gold clusters Au{sub n}C{sup ?} (n = 1–10): A density functional theory study  

SciTech Connect (OSTI)

The equilibrium geometric structures, relative stabilities, and electronic properties of Au{sub n}C{sup ?} and Au{sub n+1}{sup ?} (n = 1–10) clusters are systematically investigated using density functional theory with hyper-generalized gradient approximation. The optimized geometries show that one Au atom capped on Au{sub n?1}C{sup ?} clusters is a dominant growth pattern for Au{sub n}C{sup ?} clusters. In contrast to Au{sub n+1}{sup ?} clusters, Au{sub n}C{sup ?} clusters are most stable in a quasi-planar or three-dimensional structure because C doping induces the local non-planarity while the rest of the structure continues to grow in a planar mode, resulting in an overall non-2D configuration. The relative stability calculations show that the impurity C atom can significantly enhance the thermodynamic stability of pure gold clusters. Moreover, the effect of C atom on the Au{sub n}{sup ?} host decreases with the increase of cluster size. The HOMO-LUMO gap curves show that the interaction of the C atom with Au{sub n}{sup ?} clusters improves the chemical stability of pure gold clusters, except for Au{sub 3}{sup ?} and Au{sub 4}{sup ?} clusters. In addition, a natural population analysis shows that the charges in corresponding Au{sub n}C{sup ?} clusters transfer from the Au{sub n}{sup ?} host to the C atom. Meanwhile, a natural electronic configuration analysis also shows that the charges mainly transfer between the 2s and 2p orbitals within the C atom.

SciTech Connect (OSTI)

Hot electron flow generated on colloid platinum nanoparticles during exothermic catalytic carbon monoxide oxidation was directly detected with Au/TiO{sub 2} diodes. Although Au/TiO{sub 2} diodes are not catalytically active, platinum nanoparticles on Au/TiO{sub 2} exhibit both chemicurrent and catalytic turnover rate. Hot electrons are generated on the surface of the metal nanoparticles and go over the Schottky energy barrier between Au and TiO{sub 2}. The continuous Au layer ensures that the metal nanoparticles are electrically connected to the device. The overall thickness of the metal assembly (nanoparticles and Au thin film) is comparable to the mean free path of hot electrons, resulting in ballistic transport through the metal. The chemicurrent and chemical reactivity of nanoparticles with citrate, hexadecylamine, hexadecylthiol, and TTAB (Tetradecyltrimethylammonium Bromide) capping agents were measured during catalytic CO oxidation at pressures of 100 Torr O{sub 2} and 40 Torr CO at 373-513 K. We found that chemicurrent yield varies with each capping agent, but always decreases with increasing temperature. We suggest that this inverse temperature dependence is associated with the influence of charging effects due to the organic capping layer during hot electron transport through the metal-oxide interface.

Optical and electronic properties of mixed Ag-Au tetramer cations  

SciTech Connect (OSTI)

We present experimental and theoretical studies of the optical response of mixed Ag {sub n} Au {sub 4?n}{sup +} (n=1–3) clusters in the photon energy range ?? = 1.9–3.5 eV. Absorption spectra are recorded by a newly built longitudinal molecular beam depletion spectroscopy apparatus providing lower limits to absolute photodissociation cross sections. The experimental data are compared to optical response calculations in the framework of long-range corrected time-dependent density functional theory with initial cluster geometries obtained by the unbiased Birmingham Cluster Genetic Algorithm coupled with density functional theory. Experiments and excited state calculations shed light on the structural and electronic properties of the mixed Ag-Au tetramer cations.

SN 2012au: A GOLDEN LINK BETWEEN SUPERLUMINOUS SUPERNOVAE AND THEIR LOWER-LUMINOSITY COUNTERPARTS  

SciTech Connect (OSTI)

We present optical and near-infrared observations of SN 2012au, a slow-evolving supernova (SN) with properties that suggest a link between subsets of energetic and H-poor SNe and superluminous SNe. SN 2012au exhibited conspicuous Type-Ib-like He I lines and other absorption features at velocities reaching Almost-Equal-To 2 Multiplication-Sign 10{sup 4} km s{sup -1} in its early spectra, and a broad light curve that peaked at M{sub B} = -18.1 mag. Models of these data indicate a large explosion kinetic energy of {approx}10{sup 52} erg and {sup 56}Ni mass ejection of M{sub Ni} Almost-Equal-To 0.3 M{sub Sun} on par with SN 1998bw. SN 2012au's spectra almost one year after explosion show a blend of persistent Fe II P-Cyg absorptions and nebular emissions originating from two distinct velocity regions. These late-time emissions include strong [Fe II], [Ca II], [O I], Mg I], and Na I lines at velocities {approx}> 4500 km s{sup -1}, as well as O I and Mg I lines at noticeably smaller velocities {approx}< 2000 km s{sup -1}. Many of the late-time properties of SN 2012au are similar to the slow-evolving hypernovae SN 1997dq and SN 1997ef, and the superluminous SN 2007bi. Our observations suggest that a single explosion mechanism may unify all of these events that span -21 {approx}< M{sub B} {approx}< -17 mag. The aspherical and possibly jetted explosion was most likely initiated by the core collapse of a massive progenitor star and created substantial high-density, low-velocity Ni-rich material.

Charged-to-neutral correlation at forward rapidity in Au+Au collisions at $\\sqrt{s_{NN}}$=200 GeV  

E-Print Network [OSTI]

Event-by-event fluctuations of the ratio of inclusive charged to photon multiplicities at forward rapidity in Au+Au collision at $\\sqrt{s_{NN}}$=200 GeV have been studied. Dominant contribution to such fluctuations is expected to come from correlated production of charged and neutral pions. We search for evidences of dynamical fluctuations of different physical origins. Observables constructed out of moments of multiplicities are used as measures of fluctuations. Mixed events and model calculations are used as baselines. Results are compared to the dynamical net-charge fluctuations measured in the same acceptance. A non-zero statistically significant signal of dynamical fluctuations is observed in excess to the model prediction when charged particles and photons are measured in the same acceptance. We find that, unlike dynamical net-charge fluctuation, charge-neutral fluctuation is not dominated by correlation due to particle decay. Results are compared to the expectations based on the generic production mechanism of pions due to isospin symmetry, for which no significant (<1%) deviation is observed.

Identified particle production, azimuthal anisotropy, and interferometry measurements in Au+Au collisions at sqrt sNN = 9.2 GeV  

SciTech Connect (OSTI)

We present the first measurements of identified hadron production, azimuthal anisotropy, and pion interferometry from Au+Au collisions below the nominal injection energy at the Relativistic Heavy-Ion Collider (RHIC) facility. The data were collected using the large acceptance STAR detector at {radical}s{sub NN} = 9.2 GeV from a test run of the collider in the year 2008. Midrapidity results on multiplicity density (dN/dy) in rapidity (y), average transverse momentum (), particle ratios, elliptic flow, and HBT radii are consistent with the corresponding results at similar {radical}s{sub NN} from fixed target experiments. Directed flow measurements are presented for both midrapidity and forward rapidity regions. Furthermore the collision centrality dependence of identified particle dN/dy, , and particle ratios are discussed. These results also demonstrate that the capabilities of the STAR detector, although optimized for {radical}s{sub NN} = 200 GeV, are suitable for the proposed QCD critical point search and exploration of the QCD phase diagram at RHIC.

Measurement of the higher-order anisotropic flow coefficients for identified hadrons in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$ = 200 GeV  

E-Print Network [OSTI]

New PHENIX measurements of the anisotropic flow coefficients $v_2\\{\\Psi_2\\}$, $v_3\\{\\Psi_3\\}$, $v_4\\{\\Psi_4\\}$ and $v_4\\{\\Psi_2\\}$ for identified particles ($\\pi^{\\pm}$, $K^{\\pm}$, and $p+\\bar{p}$) obtained relative to the event planes $\\Psi_n$ in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$ = 200 GeV are presented as functions of collision centrality and particle transverse momenta $p_T$. The $v_n$ coefficients show characteristic patterns consistent with hydrodynamical expansion of the matter produced in the collisions. For each harmonic $n$, a modified valence quark number $n_q$ scaling plotting $v_n/(n_q)^{n/2}$ versus ${\\rm KE}_T/n_q$ is observed to yield a single curve for all the measured particle species for a broad range of transverse kinetic energies ${\\rm KE}_T$. A simultaneous blast wave model fit to the observed particle spectra and $v_n(p_T)$ coefficients identifies spatial eccentricities $s_n$ at freeze-out, which are much smaller than the initial-state geometric values.

Elliptic flow from two- and four-particle correlations in Au + Au collisions at {radical}s{sub NN} = 130 GeV  

SciTech Connect (OSTI)

Elliptic flow holds much promise for studying the early-time thermalization attained in ultrarelativistic nuclear collisions. Flow measurements also provide a means of distinguishing between hydrodynamic models and calculations which approach the low density (dilute gas) limit. Among the effects that can complicate the interpretation of elliptic flow measurements are azimuthal correlations that are unrelated to the reaction plane (non-flow correlations). Using data for Au + Au collisions at {radical}s{sub NN} = 130 GeV from the STAR TPC, it is found that four-particle correlation analyses can reliably separate flow and non-flow correlation signals. The latter account for on average about 15 percent of the observed second-harmonic azimuthal correlation, with the largest relative contribution for the most peripheral and the most central collisions. The results are also corrected for the effect of flow variations within centrality bins. This effect is negligible for all but the most central bin , where the correction to the elliptic flow is about a factor of two. A simple new method for two-particle flow analysis based on scalar products is described. An analysis based on the distribution of the magnitude of the flow vector is also described.

Kaon production and kaon to pion ratio in Au+Au collisions at {radical}(s{sub NN})=130 GeV  

SciTech Connect (OSTI)

Mid-rapidity transverse mass spectra and multiplicity densities of charged and neutral kaons are reported for Au+Au collisions at {radical}s{sub NN}=130 GeV at RHIC. The spectra are exponential in transverse mass, with an inverse slope of about 280 MeV in central collisions. The multiplicity densities for these particles scale with the negative hadron pseudo-rapidity density. The charged kaon to pion ratios are K{sup +}/{pi}{sup -} = 0.161 {+-} 0.002(stat) {+-} 0.024(syst) and K{sup -}/{pi}{sup -} = 0.146 {+-} 0.002(stat) {+-} 0.022(syst) for the most central collisions. The K{sup +}/{pi}{sup -} ratio is lower than the same ratio observed at the SPS while the K{sup -}/{pi}{sup -} is higher than the SPS result. Both ratios are enhanced by about 50% relative to p+p and {bar p}+p collision data at similar energies.

Measurement of the higher-order anisotropic flow coefficients for identified hadrons in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$ = 200 GeV  

E-Print Network [OSTI]

New PHENIX measurements of the anisotropic flow coefficients $v_2\\{\\Psi_2\\}$, $v_3\\{\\Psi_3\\}$, $v_4\\{\\Psi_4\\}$ and $v_4\\{\\Psi_2\\}$ for identified particles ($\\pi^{\\pm}$, $K^{\\pm}$, and $p+\\bar{p}$) obtained relative to the event planes $\\Psi_n$ in Au$+$Au collisions at $\\sqrt{s_{_{NN}}}$ = 200 GeV are presented as functions of collision centrality and particle transverse momenta $p_T$. The $v_n$ coefficients show characteristic patterns consistent with hydrodynamical expansion of the matter produced in the collisions. For each harmonic $n$, a modified valence quark number $n_q$ scaling plotting $v_n/(n_q)^{n/2}$ versus ${\\rm KE}_T/n_q$ is observed to yield a single curve for all the measured particle species for a broad range of transverse kinetic energies ${\\rm KE}_T$. A simultaneous blast wave model fit to the observed particle spectra and $v_n(p_T)$ coefficients identifies spatial eccentricities $s_n$ at freeze-out, which are much smaller than the initial-state geometric values.

Possible observables for chiral electric separation effect in Cu + Au collisions  

E-Print Network [OSTI]

The quark-gluon plasma (QGP) generated in relativistic heavy-ion collisions could be locally P- and CP-odd. In P- and CP-odd QGP, the electric field may induce a chiral current which is called chiral electric separation effect (CESE). We propose two possible observables for CESE in Cu + Au collisions: The first one is the correlation $\\zeta_{\\alpha\\beta}=\\langle \\cos[2(\\phi_\\alpha+\\phi_\\beta-2\\Psi_{\\rm RP})]\\rangle$; the second one is the charge-dependent event-plane angle $\\Psi^{q}_2$ with $q=\\pm$ being charge. Nonzero $\\Delta\\zeta=\\zeta_{opp}-\\zeta_{same}$ and $\\Delta\\Psi=\\langle\\Psi_2^+-\\Psi_2^-\\rangle$ may signal the CESE in Cu + Au collisions. Within a multiphase transport (AMPT) model, we study how the final state interaction affects these observables. We find that the correlation $\\gamma_{\\alpha\\beta}=\\langle\\cos(\\phi_{\\alpha}+\\phi_{\\beta}-\\Psi_{\\rm RP})\\rangle$ is sensitive to the out-of-plane charge separation caused by chiral magnetic effect (CME) and the in-plane charge separation caused by the in-plane electric field but not sensitive to CESE. On the other hand, $\\Delta\\zeta$ and $\\Delta\\Psi$ are sensitive to the CESE. Therefore, we suggest the future experiments to measure the above observables in Cu+Au collisions in order to disentangle different chiral and charge separation mechanisms.

Fe thin-film growth on Au(100): A self-surfactant effect and its limitations  

Science Journals Connector (OSTI)

The combination of low-energy electron diffraction intensity analyses and scanning tunneling microscopy was used to investigate the morphology and atomic structure of thin Fe films grown on Au(100) at 400 K. Deposition of only about 0.2 monolayers (ML) Fe is sufficient to lift the reconstruction of the clean substrate. In the initial growth process (<~1 ML) place exchanges between Fe and Au lead to almost two-dimensional subsurface Fe film growth with one layer of Au covering the entire film. This way, gold acts as a “self-surfactant.” Yet, there are deviations from two-dimensional growth, with a second Fe layer beginning to grow before the first one is fully completed and some substitutional disorder developing in the film because of incomplete place exchange. The amount of gold floating on the surface only gradually decreases with further increasing film thickness. At about 2 ML the surface undergoes a complete restructuring during which short “wormlike” chains of atoms form and long-range order is destroyed. Nevertheless, the existence of large terraces of little roughness proves that some surface activity of gold remains. At coverages of several ML, long-range order is reestablished with the Fe film growing in an undistorted bcc arrangement. Although parts of the film are still covered by gold, the surface morphology is not very different from that known for homoepitaxial growth of Fe on Fe(100), i.e., gold has stopped to serve as a “self-surfactant.”

Optical damage threshold of Au nanowires in strong femtosecond laser fields  

E-Print Network [OSTI]

Ultrashort, intense light pulses permit the study of nanomaterials in the optical non-linear regime, potentially leading to optoelectronics that operate in the petahertz domain. These non-linear regimes are often present just below the damage threshold thus requiring the careful tuning of laser parameters to avoid the melting and disintegration of the materials. Detailed studies of the damage threshold of nanoscale materials are therefore needed. We present results on the damage threshold of Au nanowires when illuminated by intense femtosecond pulses. These nanowires were synthesized with the directed electrochemical nanowire assembly (DENA) process in two configurations: (1) free-standing Au nanowires on W electrodes and (2) Au nanowires attached to fused silica slides. In both cases the wires have a single-crystalline structure. For laser pulses with durations of 108 fs and 32 fs at 790 nm at a repetition rate of 2 kHz, we find that the free-standing nanowires melt at intensities close to 3 TW/cm$^2$ and 7....

Electronic Band Calculation of LaTSb2 (T=Cu,Ag,Au)  

Science Journals Connector (OSTI)

Abstract The series of compounds LaTSb2 (T=Cu,Ag,Au) show various electronic properties. In this paper we have calculated the electronic structure of LaTSb2 from first-principles. The obtained Fermi surfaces of LaAgSb2 show strong two-dimensionality, which well agrees with the results of de Haas - van Alphen experiment. On the other hand, one of the Fermi surface of LaCuSb2 show three-dimensionality. LaAuSb2 has the intermediate properties. These different Fermi surfaces may cause the occurrence of the charge density wave (CDW) in LaAgSb2 and LaAuSb2, and no occurrence of the CDW in LaCuSb2. The conduction electrons are mainly due to Sb-5p electrons, while La-d and T-d electrons also have considerable contribution. The calculated electronic specific heat coefficient well agrees with the experimental results. The energy dispersion curve shows some Dirac points in the case of scalar-relativistic calculation, but these Dirac points are disappeared when we take the spin-orbit interaction into account.

In situ Formation of Highly Conducting Covalent Au-C Contacts for Single-Molecule Junctions  

SciTech Connect (OSTI)

Charge transport across metal-molecule interfaces has an important role in organic electronics. Typically, chemical link groups such as thiols or amines are used to bind organic molecules to metal electrodes in single-molecule circuits, with these groups controlling both the physical structure and the electronic coupling at the interface. Direct metal-carbon coupling has been shown through C60, benzene and {pi}-stacked benzene but ideally the carbon backbone of the molecule should be covalently bonded to the electrode without intervening link groups. Here, we demonstrate a method to create junctions with such contacts. Trimethyl tin (SnMe{sub 3})-terminated polymethylene chains are used to form single-molecule junctions with a break-junction technique. Gold atoms at the electrode displace the SnMe{sub 3} linkers, leading to the formation of direct Au-C bonded single-molecule junctions with a conductance that is {approx}100 times larger than analogous alkanes with most other terminations. The conductance of these Au-C bonded alkanes decreases exponentially with molecular length, with a decay constant of 0.97 per methylene, consistent with a non-resonant transport mechanism. Control experiments and ab initio calculations show that high conductances are achieved because a covalent Au-C sigma ({sigma}) bond is formed. This offers a new method for making reproducible and highly conducting metal-organic contacts.

Spectral-kinetic properties of heterostructures with GaAsSb/InGaAs/GaAs-based quantum wells emitting in the range of 1.0-1.2 {mu}m  

SciTech Connect (OSTI)

The spectral-kinetic properties of heterostructures with GaAs/GaAsSb-based and GaAsSb/InGaAs/GaAs-based quantum wells, emitting in the range of 1.0-1.2 {mu}m are studied with picosecond and nanosecond temporal resolution. Intense photoluminescence in the GaAsSb/InGaAs/GaAs structure, as well as an increase in the photoluminescence wavelength by a factor of 2.5 and a shift of the location of the maximum of the peak ({approx}100 meV) to the longer-wavelength region were observed up to room temperature. It is established that as the molar fraction of Sb and the thickness of the InGaAs layer increase, the energy of the fundamental transition decreases by a factor of 140 meV compared with the GaAsSb/InGaAs/GaAs structure with a lower Sb content and a smaller thickness of the InGaAs layer. At 300 K, the emission wavelength of such a structure was 1.18 {mu}m. In addition, an increase in the thickness of the InGaAs layer led to an increase in the room-temperature photoluminescence intensity by a factor of 60, which is associated with a decrease in the energy of the fundamental state for electrons in the InGaAs layer and, consequently, to larger electron localization and smaller temperature quenching of photoluminescence.

A photoemission study of Au, Ge, and O{sub 2} deposition on NH{sub 4}F etched Si(111)  

SciTech Connect (OSTI)

We have studied the interaction of a metal, Au, a semiconductor, Ge, and a non-metal, O{sub 2}, with the NH{sub 4}F etched Si(111) surface with photoemission spectroscopy. Two components were present in Si 2p core level spectra from the H-terminated surface. We observed the flat band condition from the as-etched, n-type, Si(111) surface. We performed stepwise depositions of Au and measured the band bending with photoemission spectroscopy. The Fermi level pinned near mid-gap as Au was deposited onto the as-etched surface. After the deposition of 1 ML of Au, a Au-silicide layer formed. This interfacial component indicated that the passivating H layer was compromised. As the Au coverage was increased, layers of pure Au formed between the bulk silicon and the Au-silicide layer. The observed behavior was nearly identical to that of Au deposition on the Si(111) 7 {times} 7 surface. Next, we tested the ability of the monohydride layer to sustain surfactant assisted growth of Ge. Ge islanding was observed at 400{degree}C indicating that good surfactant growth was not obtained. Although the monohydride layer was not a good surfactant for the Si(111) surface at this temperature, further study at different temperatures is needed to determine the ability of the ideal monohydride layer to act as a surfactant. Finally, we observed no oxidation of the as-etched surface at room temperature upon exposure to molecular oxygen.

Energy dependence of pi, p and pbar transverse momentum spectra for Au+Au collisions at sqrt sNN = 62.4 and 200 GeV  

SciTech Connect (OSTI)

We study the energy dependence of the transverse momentum (pT) spectra for charged pions, protons and anti-protons for Au+Au collisions at sqrt sNN = 62.4 and 200 GeV. Data are presented at mid-rapidity (lbar y rbar< 0.5) for 0.2< pT< 12 GeV/c. In the intermediate pT region (2< pT< 6 GeV/c), the nuclear modification factor is higher at 62.4 GeV than at 200 GeV, while at higher pT (pT> 7 GeV/c) the modification is similar for both energies. The p/pi+ and pbar/pi- ratios for central collisions at sqrt sNN = 62.4 GeV peak at pT _~;; 2 GeV/c. In the pT range where recombination is expected to dominate, the p/pi+ ratios at 62.4 GeV are larger than at 200 GeV, while the pbar/pi- ratios are smaller. For pT> 2 GeV/c, the pbar/pi- ratios at the two beam energies are independent of pT and centrality indicating that the dependence of the pbar/pi- ratio on pT does not change between 62.4 and 200 GeV. These findings challenge various models incorporating jet quenching and/or constituent quark coalescence.

Some conclusive considerations on the comparison of the ICARUS nu_mu to nu_e oscillation search with the MiniBooNE low-energy event excess  

E-Print Network [OSTI]

A sensitive search for anomalous LSND-like nu_mu to nu_e oscillations has been performed by the ICARUS Collaboration exposing the T600 LAr-TPC to the CERN to Gran Sasso (CNGS) neutrino beam. The result is compatible with the absence of additional anomalous contributions giving a limit to oscillation probability of 3.4E-3 and 7.6E-3 at 90% and 99% confidence levels respectively showing a tension between these new limits and the low-energy event excess (200 energy excess has been performed, including the energy resolution as obtained from the official MiniBooNE data release. As a result the previously reported tension is confirmed at 90% C.L., suggesting an unexplained nature or an otherwise instrumental effect for the MiniBooNE low energy event excess

Optical remote monitoring of CH/sub 4/ gas using low-loss optical fiber link and InGaAsP light-emitting diode in 1. 33-. mu. m region  

SciTech Connect (OSTI)

Purely optical remote monitoring of low-level CH/sub 4/ gas is realized for the first time by the method employing a 2-km long-distance, low-loss silica optical fiber link and a compact absorption cell in conjunction with a high radiant InGaAsP light-emitting diode (LED) at 1.33 ..mu..m. Based on the present experiment, the detection limit of CH/sub 4/ in air was confirmed to be approximately 2000 ppm, i.e., 4% of the lower explosion limit of CH/sub 4/. This result supports the conclusion that the fully optical remote sensing system incorporating ultralow loss optical fiber networks and near infrared LEDs or laser diodes can be extensively used for the detection and surveillance of various inflammable and/or explosive gases in industrial and mining complexes as well as in residential areas.

SciTech Connect (OSTI)

We present 2817 new southern proper motion systems with 0.''40 yr{sup -1} > {mu} {>=} 0.''18 yr{sup -1} and declination between -47{sup 0} and 00{sup 0}. This is a continuation of the SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky. We use the same photometric relations as previous searches to provide distance estimates based on the assumption that the objects are single main-sequence stars. We find 79 new red dwarf systems predicted to be within 25 pc, including a few new components of previously known systems. Two systems-SCR 1731-2452 at 9.5 pc and SCR 1746-3214 at 9.9 pc-are anticipated to be within 10 pc. We also find 23 new white dwarf (WD) candidates with distance estimates of 15-66 pc, as well as 360 new red subdwarf candidates. With this search, we complete the SCR sweep of the southern sky for stars with {mu} {>=} 0.''18 yr{sup -1} and R{sub 59F} {<=} 16.5, resulting in a total of 5042 objects in 4724 previously unreported proper motion systems. Here we provide selected comprehensive lists from our SCR proper motion search to date, including 152 red dwarf systems estimated to be within 25 pc (9 within 10 pc), 46 WDs (10 within 25 pc), and 598 subdwarf candidates. The results of this search suggest that there are more nearby systems to be found at fainter magnitudes and lower proper motion limits than those probed so far.

The Widths of the L-Series Lines and of the Energy Levels of Au(79)  

Science Journals Connector (OSTI)

Following a résumé of the Weisskopf-Wigner theory of the shape of spectral lines, and, making certain simplifying assumptions, an expression is derived for the shape of an x-ray absorption discontinuity for the case where absorption is due to the ejection of electrons from inner orbits to the continuum of unoccupied Fermi-Sommerfeld levels. If these levels be assumed equally distributed, the curve (? vs. ?) is a simple arctangent, from which the width of the associated energy level (K, L?), corresponding to the full width of half-maximum of a radiated line, may be read directly. A more complicated expression results if the Fermi-Sommerfeld levels be not equally distributed. It is shown that the predicted shape of an absorption limit agrees reasonably well with the observed shape of the LIII limit of Au(79), the width of which was found to be 4.4 volts. Data are presented on the widths of some 23 lines in the L-series of Au(79), obtained by a two-crystal spectrometer. These widths, corrected for effect of the crystals, vary from 7.6 to 20.8 volts. Making use of the conclusion of Weisskopf and Wigner, that the width of a line may be interpreted as the sum of the widths of the energy states involved, and starting from the value 4.4 volts for the width of the LIII state, the widths of the several L, M, N and O states of Au(79) are computed. For a given total quantum number n, the width decreases with increasing orbital quantum number l. States having the same value of n, l have nearly the same width. For any given l, the L states are narrowest.

INTERMEDIATE-MASS HOT CORES AT {approx}500 AU: DISKS OR OUTFLOWS?  

SciTech Connect (OSTI)

Observations with the Plateau de Bure Interferometer in the most extended configuration toward two intermediate-mass star-forming regions, IRAS 22198+6336 and AFGL 5142, reveal the presence of several complex organic molecules at {approx}500 AU scales, confirming the presence of hot cores in both regions. The hot cores are not rich in CN-bearing molecules, as often seen in massive hot cores, and are mainly traced by CH{sub 3}CH{sub 2}OH, (CH{sub 2}OH){sub 2}, CH{sub 3}COCH{sub 3}, and CH{sub 3}OH, with, additionally, CH{sub 3}CHO, CH{sub 3}OD, and HCOOD for IRAS 22198+6336, and C{sub 6}H and O{sup 13}CS for AFGL 5142. The emission of complex molecules is resolved down to sizes of {approx}300 and {approx}600 AU, for IRAS 22198+6336 and AFGL 5142, respectively, and most likely is tracing protostellar disks rather than flattened envelopes or toroids as is usually found. This is especially clear for the case of IRAS 22198+6336, where we detect a velocity gradient for all the mapped molecules perpendicular to the most chemically rich outflow of the region, yielding a dynamic mass {approx}> 4 M{sub Sun }. As for AFGL 5142, the hot core emission is resolved into two elongated cores separated {approx}1800 AU. A detailed comparison of the complex molecule peaks to the new CO (2-1) data and H{sub 2}O maser data from the literature suggests also that for AFGL 5142 the complex molecules are mainly associated with disks, except for a faint and extended molecular emission found to the west, which is possibly produced in the interface between one of the outflows and the dense surrounding gas.

Nuclear Effects on Hadron Production in d+Au and p+p Collisions at sqrt(s_NN)=200 GeV  

E-Print Network [OSTI]

PHENIX has measured the centrality dependence of mid-rapidity pion, kaon and proton transverse momentum distributions in d+Au and p+p collisions at sqrt(s_NN) = 200 GeV. The p+p data provide a reference for nuclear effects in d+Au and previously measured Au+Au collisions. Hadron production is enhanced in d+Au, relative to independent nucleon-nucleon scattering, as was observed in lower energy collisions. The nuclear modification factor for (anti) protons is larger than that for pions. The difference increases with centrality, but is not sufficient to account for the abundance of baryon production observed in central Au+Au collisions at RHIC. The centrality dependence in d+Au shows that the nuclear modification factor increases gradually with the number of collisions suffered by each participant nucleon. We also present comparisons with lower energy data as well as with parton recombination and other theoretical models of nuclear effects on particle production.

2D Au@PNiPAM microgel arrays suitable for photonic devices with thermally controlled interparticle gap  

E-Print Network [OSTI]

Core-shell Au@pNIPAM nanocomposites are assembled through a simple and inexpensive approach where drops of bulk nanoparticle solution are left to dry on ITO surfaces at fixed and finely tuned temperatures. Interparticle distances are determined by the length of the thermoresponsive PNiPAM shell which acts as mechanical spacer. Structural characterization is performed through microscope imaging techniques and we quantify the pair and orientational correlation functions characteristic to each array at each deposition temperature. The elasticity of the polymer shell at each temperature is considered as microgels are softer at temperatures below PNiPAM's LCST. In a second step, previously prepared Au@PNiPAM arrays are exposed to atmospheric plasma. Plasma reacts and degrades the PNiPAM shell, being non-invasive to Au cores which remain at their original array positions.

Emission patterns of neutral pions in 40A MeV Ta+Au reactions  

Science Journals Connector (OSTI)

Differential cross sections of neutral pions emitted in Ta181+Au197 collisions at a beam energy of 39.5A MeV have been measured with the two-arm photon spectrometer (TAPS). The kinetic energy and transverse momentum spectra of neutral pions cannot be properly described in the framework of the thermal model, nor when the reabsorption of pions is accounted for in a phenomenological model. However, high energy and high momentum tails of the pion spectra can be well fitted through thermal distributions with unexpectedly soft temperature parameters below 10 MeV.

Disappearance of rotational flow and reaction plane dispersions in Kr+Au collisions

Two-particle azimuthal correlations have been used to extract reaction plane dispersion free triple-differential cross sections for d, t, and ? particles for the midcentral collisions of 84Kr+197Au at E/A=35, 55, and 70 MeV. Both experimental measurements and extrapolations from lower incident energies suggest that rotational flow disappears at E/A?100 MeV for light charged particles and that reaction plane dispersions introduce large uncertainties in extracting the disappearance of rotational flow.

Nuclear k_T in d+Au Collisions from Multiparticle Jet Reconstruction at STAR  

E-Print Network [OSTI]

This paper presents the most recent nuclear k_T measurements from STAR derived from multiparticle jet reconstruction of d+Au and p+p collisions at sqrt(s)=200 GeV. Since jets reconstructed from multiple particles are relatively free of fragmentation biases, nuclear k_T can be measured with greater certainty in this way than with traditional di-hadron correlations. Multi-particle jet reconstruction can also be used for a direct measurement of the fragmentation function.

Photochemical Production of Oligothiophene and Polythiophene Micropatterns from 2,5-diiodothiophene on Au in UHV  

SciTech Connect (OSTI)

Fabrication of oligothiophene and polythiophene micropatterns is demonstrated by photochemical reactions of 2, 5-diiodothiophene adsorbed on an Au coated Si wafer under UHV conditions. For patterning, a TEM grid is utilized as a model stencil mask. Fluorescence microscopic analysis shows that polymer microstructures with good pattern fidelity are attained over a large area. RAIRS and NEXAFS analyses indicate that the electronic and molecular structures of the produced polymer are similar to those of chemically synthesized polythiophene. The structural defects of the photochemically produced polymer are negligible. The present procedure provides a very efficient strategy for growth and patterning of conjugated polymer microstructures with high quality in one step.

Heat transfer coefficient saturation in superconducting Nb tunnel junctions contacted to a NbTiN circuit and an Au energy relaxation layer  

E-Print Network [OSTI]

In this paper we present the experimental realization of a Nb tunnel junction connected to a high-gap superconducting NbTiN embedding circuit. We investigate relaxation of nonequilibrium quasiparticles in a small volume Au layer between the Nb tunnel junction and the NbTiN circuit. We find a saturation in the effective heat-transfer coefficient consistent with a simple theoretical model. This saturation is determined by the thickness of the Au layer. Our findings are important for the design of the ideal Au energy relaxation layer for practical SIS heterodyne mixers and we suggest two geometries, one, using a circular Au layer and, two, using a half-circular Au layer. Our work is concluded with an outlook of our future experiments.

Performance test of Ti/Au bilayer TES microcalorimeter in combination with continuous ADR  

SciTech Connect (OSTI)

Performance test of a Ti/Au bilayer TES microcalorimeter has been made in combination with a continuous adiabatic demagnetization refrigerator (CADR). The CADR has four stages of ADR to produce continuous cooling by recycling them in dedicated order, and is cryogen-free utilizing a 4K-GM refrigerator. We installed a Ti/Au bilayer TES microcalorimeter and 420-series SQUID array to readout the X-ray signal on the 1st (coldest) stage of the CADR. We successfully operated the CADR at temperature of 120 mK in continuous mode more than 27 hr, however, FWHM energy resolution of the TES microcalorimeter was degraded to 45 eV at 6 keV, as compared to 10 eV when measured in a dilution refrigerator. This is mainly because the temperature stability was not good enough (about 0.6 mK) and the operation temperature was not sufficiently lower than the transition temperature T{sub c} = 135mK of the TES. We operated the TES microcalorimeter at the operation temperature of 105 mK in one-shot mode and the resolution was improved to 30 eV. We also found that the operating point of the TES was affected by the magnetic field of the 3rd and 4th ADR recycle. More complete shielding of the magnetic field is essential for further improvement of the performance of the TES microcalorimeter.

A LUMINOUS AND FAST-EXPANDING TYPE Ib SUPERNOVA SN 2012au  

SciTech Connect (OSTI)

We present a set of photometric and spectroscopic observations of a bright Type Ib supernova SN 2012au from -6 days until {approx} + 150 days after maximum. The shape of its early R-band light curve is similar to that of an average Type Ib/c supernova. The peak absolute magnitude is M{sub R} = -18.7 {+-} 0.2 mag, which suggests that this supernova belongs to a very luminous group among Type Ib supernovae. The line velocity of He I {lambda}5876 is about 15,000 km s{sup -1} around maximum, which is much faster than that in a typical Type Ib supernova. From the quasi-bolometric peak luminosity of (6.7 {+-} 1.3) Multiplication-Sign 10{sup 42} erg s{sup -1}, we estimate the {sup 56}Ni mass produced during the explosion as {approx}0.30 M{sub Sun }. We also give a rough constraint to the ejecta mass 5-7 M{sub Sun} and the kinetic energy (7-18) Multiplication-Sign 10{sup 51} erg. We find a weak correlation between the peak absolute magnitude and He I velocity among Type Ib SNe. The similarities to SN 1998bw in the density structure inferred from the light-curve model as well as the large peak bolometric luminosity suggest that SN 2012au had properties similar to energetic Type Ic supernovae.

Possible observables for chiral electric separation effect in Cu + Au collisions  

E-Print Network [OSTI]

The quark-gluon plasma (QGP) generated in relativistic heavy-ion collisions could be locally P- and CP-odd. In P- and CP-odd QGP, the electric field may induce a chiral current which is called chiral electric separation effect (CESE). We propose two possible observables for CESE in Cu + Au collisions: The first one is the correlation $\\zeta_{\\alpha\\beta}=\\langle \\cos[2(\\phi_\\alpha+\\phi_\\beta-2\\Psi_{\\rm RP})]\\rangle$; the second one is the charge-dependent event-plane angle $\\Psi^{q}_2$ with $q=\\pm$ being charge. Nonzero $\\Delta\\zeta=\\zeta_{opp}-\\zeta_{same}$ and $\\Delta\\Psi=\\langle\\Psi_2^+-\\Psi_2^-\\rangle$ may signal the CESE in Cu + Au collisions. Within a multiphase transport (AMPT) model, we study how the final state interaction affects these observables. We find that the correlation $\\gamma_{\\alpha\\beta}=\\langle\\cos(\\phi_{\\alpha}+\\phi_{\\beta}-\\Psi_{\\rm RP})\\rangle$ is sensitive to the out-of-plane charge separation caused by chiral magnetic effect (CME) and the in-plane charge separation caused by the in-...
