Decay of Ar41  

Science Journals Connector (OSTI)

A weak gamma ray has been found in the decay of Ar41 to K41. The energy of the gamma ray is 1.6640.007 MeV; and its intensity, relative to that of the strong 1.293-MeV gamma ray, is (52)10-4. It is concluded from the results of conincidence measurements that this gamma ray is the result of a beta-ray branch from Ar41 leading to an excited state in K41 at 1.664 MeV. The associated logft value is found to be 7.70.3. The spin and parity of the 1.664-MeV state in K41 are most probably 52+ or 72+.

1 arXiv:nucl-th/0305016v1 7 May 2003Non-Scissors-Mode Behaviour of Isovector Magnetic Dipole Orbital Transitions Involving Isospin Transfer  

E-Print Network (OSTI)

We study the response of isovector orbital magnetic dipole (IOMD) transitions to the quadrupole-quadrupole (Q Q) interaction, to the isospinconserving pairing interaction (ICP) and to combinations of both. We find qualitatively different behaviours for transitions in which the final isospin differs from the initial isospin versus cases where the two isospins are the same. For N = Z even-even nuclei with J ? = 0 +, T = 0 ground states such as 8Be and 20Ne, the summed T = 0 ? T = 1 IOMD from the ground state to all the J = 1, T = 1 states in the 0h? space does not vanish when the Q Q interaction is turned off. The pairing interaction (ICP) alone leads to a finite transition rate. For nuclei with J = 0 +, T = 1 ground states such 2 as 10Be and 22Ne, the summed T = 1 ? T = 1 IOMD does vanish when the Q Q interaction is turned off, as is expected in a good scissors-mode behaviour. However this is not the case for the corresponding sum of the T = 1 ? T = 2 IOMD transitions. In 22Ne (but not in 10Be) the sum of the T = 1 ? T = 2 IOMD transitions is remarkably insensitive to the strengths of both the Q Q and the ICP interactions. In 22Ne an energy weighted-sum is similarly insensitive. All our calculations were carried out in the 0h? space. I.

Studies of Ar41 from the Ar40(d,p?)Ar41 Reaction  

Science Journals Connector (OSTI)

Particle-gamma coincidence measurements on the Ar40(d,p?)Ar41 reaction have been used to determine branching ratios for the gamma deexcitation of several Ar41 states of excitation energy less than 3.5 MeV. Gas targets of 99.6% Ar40 and a deuteron bombarding energy of 3.5 MeV were used for these measurements. Proton-gamma angular correlations were also studied at ED=3.2 MeV, utilizing a collinear geometry with protons detected in an annular counter placed at 180 and gamma rays detected at several angles between 0 and 90 relative to the beam direction. These data eliminate possible spin assignments of for the levels at 0.517 and 1.354 MeV and when combined with previous work lead to a J?=32- assignment for both of these states.

40Ar/39Ar ages from Fra Mauro  

Science Journals Connector (OSTI)

High temperature40Ar/39Ar ages have been determined for four rock fragments selected from coarse fines returned from Fra Mauro. Three are fragmental rocks in varying stages of recrystallization and the fourth is crystalline with a gabbro mineralogy, relatively devoid of shock features. All of the fragments have a common age of 3.75 0.15 109 yr. The ages suggest intense activity, possibly the Imbrium event, at 3.75 109 yr ago which has precluded the identification of more primitive material.

L-shell x-ray cross sections for Cl-Ar and Ar-Ar collisions  

Science Journals Connector (OSTI)

Measurements of total x-ray production cross sections for Ar+ -Ar and Cl+ -Ar collisions for incident energies between 200 keV and 1.5 MeV are reported. For Cl+ -Ar collisions, separate argon and chlorine x-ray production cross sections are extracted. The cross sections exhibit steep increases as bombarding energy is increased. Using existing measurements of Auger cross sections, values for the mean fluorescence yields as a function of bombarding energy are deduced. The increases in the x-ray production cross sections are shown to be due primarily to changes in the mean fluorescence yields. A qualitative explanation for the observations is proposed.

Ultraviolet radiation produced in low-energy Ar + Ar and Kr + Kr collisions  

Science Journals Connector (OSTI)

Absolute cross sections for the emission of ultraviolet resonance line radiations from Ar and Kr atoms resulting from Ar + Ar and Kr + Kr collisions are reported. The energy range covered extends from near the reaction thresholds to 150 eV in the center-of-mass system. The emission cross sections are found to have energy dependencies very similar to those exhibited by the total ionization cross sections for the same reactants. The techniques used to make the measurements are described and the results are discussed in terms of a current theoretical model of the interactions.

Compton profiles of Ne, Ar, and Kr are calculated from ground-state energies and wave functions with full correlation contributions included. The latter is carried out by regarding atoms as inhomogeneous interacting electron-gas systems using the Kohn-Sham self-consistent scheme in the local-density approximation. The calculated values are brought closer to the experimental values from Hartree-Fock results. There are numerical problems for large atoms.

The structure and ground state dynamics of ArIH  

Science Journals Connector (OSTI)

The structure and ground state dynamics of the atomdiatom dimer interaction between Ar and HI has been investigated by microwave and near infrared supersonic jet spectroscopy.Ab initio molecular orbital calculations were used to provide greater insight into the nature of the interaction. The ground state is shown to be in the isomeric form ArIH with R cm =3.9975(1)? ?=149.33(1) for the normal isotopomer and R cm =3.9483(1)? ?=157.11(1) for ArID. The potential surface from an ab initio molecular orbital calculation was scaled and shifted to yield a nonlinear least-squares fit of the rovibrational state energies to the experimental data. The ground statepotential energy surface obtained in this manner has a barrier between the ArIH and ArHI isomers of 88.5 cm?1 with respect to the global minimum. Such calculations are also used to predict the presence of localized states in the secondary minimum associated with isomers ArHI and ArDI. Attempts to experimentally identify transitions associated with the latter were unsuccessful. The ground state ArIH isomeric structure contrasts with the corresponding ground state of the other members of the homologous series ArHX ( X=F Cl and Br) in which the Ar is bound to the proton.

Diffusion of Kr Isotopes in Solid Ar  

Science Journals Connector (OSTI)

The diffusion coefficient D=D0e-Q0RT and isotope effect for Kr78 and Kr86 in solid Ar have been measured using a tracer technique. The activation energy QKr0 depends on the interchange parameter w, but is estimated to lie in the range 3500-3900 cal mole-1, with the most reliable w giving the lower value. Thus, the two calculated QKr0 (3853 and 4050 cal mole-1) for the vacancy mechanism using a two-body (12, 6) potential appear somewhat high, but in reasonable agreement with experiment. The isotope effect gives f?K?(D78D86-1)[(8678)12-1]=0.480.25 which, since QKr0?QAr0, suggests that ?K?0.6 for a single-vacancy mechanism. {Here f is the correlation factor and ?K?(?278?286-1)[(8678)12-1], where ?2 is the tracer jump rate.}

CHEMILUMINESCENT CHEMI-IONIZATION: Ar* + Ca AND THE CaAr+ EMISSION SPECTRUM  

SciTech Connect

A flowing afterglow chemiluminescence apparatus has been used to analyze visible fluorescence in the Ar* ({sup 3}P{sub 2}{sup o}) + Ca ({sup 1}S{sub 0}) reaction. The rate constants for production of Ca{sup +} ({sup 2}P{sub 3/2}{sup o}) and Ca{sup +} ({sup 2}P{sub 1/2}{sup o}) were measured to be 1.6 x 10{sup -10} cm{sup 3}-molecule{sup -1} sec{sup -1} and 3.2 x 10{sup -11} cm{sup 3} molecule{sup -1} sec{sup -1}, respectively. These results demonstrate a transfer of the total electronic angular momentum polarization in Ar* tothe excited ion levels. The molecular band spectrum of the associative ionization product CaAr{sup +} (A{sup 2}{Pi}) was observed. Molecular fluorescence constituted 14% of the total fluorescence from all ion products. This spectrum was analyzed with a model (exp-Z4) potential, yielding, for the ground state, {Chi}{sup 2}{Sigma}{sup +}, R{sub e} = 2.8 {angstrom}, {omega}''{sub e} = 87 cm{sup -1}, and D''{sub e} = 1000 cm{sup -1}, and, for the A{sup 2}{Pi} state, R{sub e} = 2.6 {angstrom}, {omega}'{sub e} = 200 cm{sup -1}, and D'{sub e} = 4900 cm{sup -1}. The nascent internal state distribution in CaAr{sup +} is found to consist of a fairly narrow range of high vibrational levels. The analysis of spectra from chemiluminescent reaction is a well established technique for elucidating the product state distributions of elementary processes. In this paper, they use the analysis of the chemiluminescent chemi-ionization reactions between metastable argon atoms and calcium atoms to expose the dynamics of associative ionization (AI) and to measure the branching ratios for chemi-ionization into more than one product channel.

Combined U-Th/He and 40Ar/39Ar geochronology of post-shield lavas from the Mauna Kea and Kohala volcanoes, Hawaii  

SciTech Connect

Late Quaternary, post-shield lavas from the Mauna Kea and Kohala volcanoes on the Big Island of Hawaii have been dated using the {sup 40}Ar/{sup 39}Ar and U-Th/He methods. The objective of the study is to compare the recently demonstrated U-Th/He age method, which uses basaltic olivine phenocrysts, with {sup 40}Ar/{sup 39}Ar ages measured on groundmass from the same samples. As a corollary, the age data also increase the precision of the chronology of volcanism on the Big Island. For the U-Th/He ages, U, Th and He concentrations and isotopes were measured to account for U-series disequilibrium and initial He. Single analyses U-Th/He ages for Hamakua lavas from Mauna Kea are 87 {+-} 40 ka to 119 {+-} 23 ka (2{sigma} uncertainties), which are in general equal to or younger than {sup 40}Ar/{sup 39}Ar ages. Basalt from the Polulu sequence on Kohala gives a U-Th/He age of 354 {+-} 54 ka and a {sup 40}Ar/{sup 39}Ar age of 450 {+-} 40 ka. All of the U-Th/He ages, and all but one spurious {sup 40}Ar/{sup 39}Ar ages conform to the previously proposed stratigraphy and published {sup 14}C and K-Ar ages. The ages also compare favorably to U-Th whole rock-olivine ages calculated from {sup 238}U - {sup 230}Th disequilibria. The U-Th/He and {sup 40}Ar/{sup 39}Ar results agree best where there is a relatively large amount of radiogenic {sup 40}Ar (>10%), and where the {sup 40}Ar/{sup 36}Ar intercept calculated from the Ar isochron diagram is close to the atmospheric value. In two cases, it is not clear why U-Th/He and {sup 40}Ar/{sup 39}Ar ages do not agree within uncertainty. U-Th/He and {sup 40}Ar/{sup 39}Ar results diverge the most on a low-K transitional tholeiitic basalt with abundant olivine. For the most alkalic basalts with negligible olivine phenocrysts, U-Th/He ages were unattainable while {sup 40}Ar/{sup 39}Ar results provide good precision even on ages as low as 19 {+-} 4 ka. Hence, the strengths and weaknesses of the U-Th/He and {sup 40}Ar/{sup 39}Ar methods are complimentary for basalts with ages of order 100-500 ka.

Acoustic Resonance Spectroscopy (ARS) Munition Classification System enhancements. Final report  

SciTech Connect

Acoustic Resonance Spectroscopy (ARS) is a non-destructive evaluation technology developed at the Los Alamos National Laboratory (LANL). This technology has resulted in three generations of instrumentation, funded by the Defense Special Weapons Agency (DSWA), specifically designed for field identification of chemical weapon (CW) munitions. Each generation of ARS instrumentation was developed with a specific user in mind. The ARS1OO was built for use by the U.N. Inspection Teams going into Iraq immediately after the Persian Gulf War. The ARS200 was built for use in the US-Russia Bilateral Chemical Weapons Treaty (the primary users for this system are the US Onsite Inspection Agency (OSIA) and their Russian counterparts). The ARS300 was built with the requirements of the Organization for the Prohibition of Chemical Weapons (OPCW) in mind. Each successive system is an improved version of the previous system based on learning the weaknesses of each and, coincidentally, on the fact that more time was available to do a requirements analysis and the necessary engineering development. The ARS300 is at a level of development that warrants transferring the technology to a commercial vendor. Since LANL will supply the computer software to the selected vendor, it is possible for LANL to continue to improve the decision algorithms, add features where necessary, and adjust the user interface before the final transfer occurs. This paper describes the current system, ARS system enhancements, and software enhancements. Appendices contain the Operations Manual (software Version 3.01), and two earlier reports on enhancements.

Production of 37Ar in The University of Texas TRIGA reactor facility  

SciTech Connect

The detection of {sup 37}Ar is important for on-site inspections for the Comprehensive Nuclear-Test-Ban Treaty monitoring. In an underground nuclear explosion this radionuclide is produced by {sup 40}Ca(n,{alpha}){sup 37}Ar reaction in surrounding soil and rock. With a half-life of 35 days, {sup 37}Ar provides a signal useful for confirming the location of an underground nuclear event. An ultra-low-background proportional counter developed by Pacific Northwest National Laboratory is used to detect {sup 37}Ar, which decays via electron capture. The irradiation of Ar gas at natural enrichment in the 3L facility within the Mark II TRIGA reactor facility at The University of Texas at Austin provides a source of {sup 37}Ar for the calibration of the detector. The {sup 41}Ar activity is measured by the gamma activity using an HPGe detector after the sample is removed from the core. Using the {sup 41}Ar/{sup 37}Ar production ratio and the {sup 41}Ar activity, the amount of {sup 37}Ar created is calculated. The {sup 41}Ar decays quickly (half-life of 109.34 minutes) leaving a radioactive sample of high purity {sup 37}Ar and only trace levels of {sup 39}Ar.

Charge Transport in Solid and Liquid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

This paper reports an investigation of the drift velocity of excess electrons in solid and liquid Ar, Kr, and Xe. After purification of the commercially available gas, thin crystal specimens (100-600 ?m) were grown from the liquid between parallel electrodes in a chamber attached to a miniature cryostat. Pulses of 40-keV electrons were used to generate the charge carriers in both liquids and solids. This technique overcomes the limitations inherent in previously applied methods and has made it possible to investigate the drift velocity over a range of applied fields from 10 V cm-1 to 100 kV cm-1. Near the triple point, the low-field mobility ?0 in solid Ar, Kr, and Xe was found to be 1000, 3700, and about 4500 cm2sec-1V-1, respectively. In the liquids the corresponding mobilities were 475, 1800, and 2200 cm2sec-1V-1. The temerature dependence of ?0 has been measured on Ar crystals, and the results indicate that ?0 is determined by acoustic scattering. The electron lifetime appears to be controlled predominantly by oxygen impurities. Pronounced hot-electron effects are observed in drift-velocityversusfield curves for both liquids and solids, and their fit to the Shockley hot-electron theory has been investigated. In the high-field region all the curves show an almost complete saturation with field. The theory of Cohen and Lekner applied to liquid Ar fits the results over most of the field range, suggesting that the deviations from the Shockley theory at higher electron temperatures are associated with an increase in the value of the structure factor. In solid Ar or Kr, positive holes do not appear to be mobile, but in Xe crystals a hole mobility of about 210-2 cm2sec-1V-1 was found. The implications of these results are briefly discussed.

Evaluation of sintering effects on SiC incorporated UO2 kernels under Ar and Ar-4%H2 environments  

SciTech Connect

Silicon carbide (SiC) is suggested as an oxygen getter in UO2 kernels used for TRISO particle fuels to lower oxygen potential and prevent kernel migration during irradiation. Scanning electron microscopy and X-ray diffractometry analyses performed on sintered kernels verified that internal gelation process can be used to incorporate SiC in urania fuel kernels. Sintering in either Ar or Ar-4%H2 at 1500 C lowered the SiC content in the UO2 kernels to some extent. Formation of UC was observed as the major chemical phase in the process, while other minor phases such as U3Si2C2, USi2, U3Si2, and UC2 were also identified. UC formation was presumed to be occurred by two reactions. The first was the SiC reaction with its protective SiO2 oxide layer on SiC grains to produce volatile SiO and free carbon that subsequently reacted with UO2 to form UC. The second process was direct UO2 reaction with SiC grains to form SiO, CO, and UC, especially in Ar-4%H2. A slightly higher density and UC content was observed in the sample sintered in Ar-4%H2, but the use of both atmospheres produced kernels with ~95% of theoretical density. It is suggested that incorporating CO in the sintering gas would prevent UC formation and preserve the initial SiC content.

Sublimation Pressures of Solid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

Results of an experiment to measure the sublimation pressures of Ar, Kr, and Xe over wide temperature and pressure ranges are presented. Data are reported from near the respective triple points to about (2.3 10-6 Torr, 25.506 K) for Ar; (2.1 10-4 Torr, 45.130 K) for Kr; (3.8 10-4 Torr, 70.075 K) for Xe. Pressures were measured with a Hg manometer, a McLeod gauge, and a calibrated Bourdon gauge. The data have been corrected for thermomolecular flow and streaming. Temperatures were measured with a N.B.S.-calibrated Pt resistance thermometer. The application of the law of corresponding states is investigated. Values for static lattice energy, geometric mean of the lattice vibrational spectrum, heat of sublimation, and lattice vibrational energy are calculated using theoretical sublimation pressure curves.

Photoemission from Ar, Kr, and Xe on Pb(111)  

Science Journals Connector (OSTI)

Angle-resolved photoelectron spectra were measured for the valence p states of Ar, Kr, and Xe on Pb(111). The thickness of the rare-gas layers was varied between 0.05 and about 5 monolayers. For each layer the work function was deduced from the width of the photoelectron energy-distribution curve. On Pb(111) tightly packed monolayers were prepared, exhibiting energy dispersion of the valence p states, which is discussed in the framework of the known two-dimensional band structure. The spectral features are very sharp, as can be seen from the full width at half maximum value of 175 meV for the Xe 5p1/2 peak. For Xe the submonolayer regime was also studied, where single atoms are adsorbed together with small three-dimensional clusters. The single atoms exhibit no dispersion and no split of the p3/2 level into two sublevels. This demonstrates that these features are derived from lateral interaction in the rare-gas monolayer. On top of the monolayer a second completely filled layer can be prepared for Ar, Kr, and Xe. The second-layer shift in binding energy is 720 meV for Ar and Kr and 525 meV for Xe. It is about 6 times as large as the work-function changes induced by the monolayer. This observation can only be explained in the known final-state interpretation of the layer-dependent shifts in binding energy.

Two-phase Cryogenic Avalanche Detectors with THGEM and hybrid THGEM/GEM multipliers operated in Ar and Ar+N2  

E-Print Network (OSTI)

Two-phase Cryogenic Avalanche Detectors (CRADs) with GEM and THGEM multipliers have become an emerging potential technique for charge recording in rare-event experiments. In this work we present the performance of two-phase CRADs operated in Ar and Ar+N2. Detectors with sensitive area of 10x10 cm2, reaching a litre-scale active volume, yielded gains of the order of 1000 with a double-THGEM multiplier. Higher gains, of about 5000, have been attained in two-phase Ar CRADs with a hybrid triple-stage multiplier, comprising of a double-THGEM followed by a GEM. The performance of two-phase CRADs in Ar doped with N2 (0.1-0.6%) yielded faster signals and similar gains compared to the operation in two-phase Ar. The applicability to rare-event experiments is discussed.

40Ar/39Ar dating of microgram feldspar grains from the paired feldspathic achondrites GRA 06128 and 06129  

Science Journals Connector (OSTI)

Abstract 40Ar/39Ar ages of single feldspar grains from the paired meteorites Graves Nunatak 06128 (GRA8; 8 grains) and 06129 (GRA9; 26 grains) are presented. Plateau ages (?70% of the 39Ar released) ranged from 4000 to 4600Ma with an average 1-? uncertainty of 90Ma. The most precise ages obtained were 426717Ma for a grain from GRA8 and 443719Ma and 432118Ma for two grains from GRA9. Isotope correlation diagrams yield less precise ages ranging from 3800 to 5200Ma with an average 1-? uncertainty of 250Ma; they indicate a negligible trapped component. Plateau ages, integrated total fusion ages, and isochron ages are internally concordant at the 95% confidence level. The distribution of the plateau ages for GRA9 is bimodal with peaks at 4400 and 4300Ma. In contrast, the plateau age distribution for GRA8 peaks at about 4260Ma with broad wings extending toward younger and older ages. To explain the distributions of grain ages we prefer a scenario that includes a major post-formation event about 4400Ma ago and a later melt intrusion event that heated GRA8 more than some parts of GRA9.

Radial Mass Fraction Distributions In Ar+N Plasmas Produced In A Wall-Stabilized Arc  

SciTech Connect

Radial distributions of Ar mass fractions in plasmas produced in a wall-stabilized arc have been studied. Measurements have been performed for seven different mixtures of Ar+N2. The obtained results show that the radial distributions of Ar mass fractions strongly depend on the chemical composition of the plasma. In plasmas containing large amount of Ar the distributions have local minima at the arc axis (in high temperature plasma regions), whereas in plasmas consisting mainly of nitrogen the distributions reveal maxima on the discharge axis.

The sup 40 Ar/ sup 39 Ar thermochronology of the eastern Mojave Desert, California, and adjacent western Arizona with implications for the evolution of metamorphic core complexes  

SciTech Connect

The application of {sup 40}Ar/{sup 39}Ar thermochronology provides information about the timing and nature of thrusting, plutonism, metamorphism, denudation, and detachment faulting. The {sup 40}Ar/{sup 39}Ar ages of 175 to 125 Ma from the Clipper, Piute, Turtle, Mohave, Bill Williams, and Hualapai Mountains are interpreted to be the result of a middle Mesozoic thermal event(s) caused by crustal thickening. The {sup 40}Ar/{sup 39}Ar data from the Clipper and Piute Mountains suggest that this thermal event was followed by a period of cooling at rates of 1-5C/m.y. Orogenesis culminated during the Late Cretaceous when rocks exposed in the Old Woman-Piute, Chemehuevi, and Sacramento Mountains attained temperatures >500C which reset the K-Ar systems of minerals from Proterozoic rocks. High-grade metamorphism in the Old Woman Mountains area was caused by the intrusion of the Old Woman-Piute batholith at 73 {plus minus} 1 Ma. Cooling rates following batholith emplacement in the Old Woman Mountains were {approximately}100C/m.y. between 73 and 70 Ma and 5-10C/m.y. from 70 to {approximately}30 Ma. By 30 Ma, rocks exposed in the Old Woman-Piute, Marble, Ship, Clipper, and Turtle Mountains were below {approximately}100C. The {sup 49}Ar/{sup 39}Ar ages from the Sacramento Mountains suggest that mylonization caused by the onset of regional extension occurred at 23 {plus minus} 1 Ma. When extension started in the Chemehuevi Mountains, rocks exposed in the southwestern and northeastern portions of footwall to the Chemehuevi detachment fault were at {approximately}180C and {approximately}350C, respectively. Unroofing of the footwalls to detachment faults in the Sacramento and Chemehuevi Mountains resulted in average cooling rates of 10-50C/m.y. between 22 and 15 Ma.

New accurate measurement of 36ArH+ and 38ArH+ ro-vibrational transitions by high resolution IR absorption spectroscopy  

E-Print Network (OSTI)

The protonated Argon ion, $^{36}$ArH$^{+}$, has been identified recently in the Crab Nebula (Barlow et al. 2013) from Herschel spectra. Given the atmospheric opacity at the frequency of its $J$=1-0 and $J$=2-1 rotational transitions (617.5 and 1234.6 GHz, respectively), and the current lack of appropriate space observatories after the recent end of the Herschel mission, future studies on this molecule will rely on mid-infrared observations. We report on accurate wavenumber measurements of $^{36}$ArH$^{+}$ and $^{38}$ArH$^{+}$ rotation-vibration transitions in the $v$=1-0 band in the range 4.1-3.7 $\\mu$m (2450-2715 cm$^{-1}$).

Multiphoton Double Ionization of Ar in Intense Extreme Ultraviolet Laser Fields Studied by Shot-by-Shot Photoelectron Spectroscopy  

SciTech Connect

Photoelectron spectroscopy has been performed to study the multiphoton double ionization of Ar in an intense extreme ultraviolet laser field (h{nu}{approx}21 eV, {approx}5 TW/cm{sup 2}), by using a free electron laser (FEL). Three distinct peaks identified in the observed photoelectron spectra clearly show that the double ionization proceeds sequentially via the formation of Ar{sup +}: Ar+h{nu}{yields}Ar{sup +}+e{sup -} and Ar{sup +}+2h{nu}{yields}Ar{sup 2+}+e{sup -}. Shot-by-shot recording of the photoelectron spectra allows simultaneous monitoring of FEL spectrum and the multiphoton process for each FEL pulse, revealing that the two-photon ionization from Ar{sup +} is significantly enhanced by intermediate resonances in Ar{sup +}.

Reactions of Ar40 with Dy160, Dy164, and Yb174  

Science Journals Connector (OSTI)

Excitation functions for nuclear reactions induced by Ar40 ions were measured for the reactions Dy164(Ar40,xn)Po204-x, Dy160(Ar40,xn)Po200-x, Yb174(Ar40,xn)Ra214-x, and Yb174(Ar40,pxn)Fr213-x. For all of the systems studied, the (Ar,xn) reactions only make up a small part of the total reaction cross section of ?2 b; the largest cross sections encountered in each system were (at the peaks of the respective excitation functions) 30 mb for Dy164(Ar,5n), 10 mb for Dy160(Ar,4n), and 5 mb for Yb174(Ar,4n-5n). The probabilities Pxn of neutron emission in the compound systems Po204 and Po200 were found to be very different, with respective maximum probabilities for the emission of four, five, and six neutrons of 0.064, 0.035, and 0.016 for Po204, and 0.010, 0.0025, and 0.0003 for Po200. Calculations performed with a statistical-model code, which includes angular-momentum effects and fission competition, are able to reproduce the shapes and magnitudes of the experimental excitation functions, although there is a systematic energy difference, ?10 MeV, between theory and the data. These model-dependent analyses describe in detail how the particle evaporation and fission deexcitation modes vary with angular momentum and excitation energy. The observed large differences in Pxn values for Po204 and Po200 are seen to arise from the small difference, ?1.2 MeV, between the values of Sn-Bf, the difference of neutron-separation and fission-barrier energies, in each compound system.NUCLEAR REACTIONS Dy160(Ar40,xn)Po200-x, Dy164(Ar40,xn)Po204-x, Yb174(Ar40,xn)Ra214-x, and Yb174(Ar40,pxn)Fr213-x.

GAS AND DUST ABSORPTION IN THE DoAr 24E SYSTEM  

SciTech Connect

We present findings for DoAr 24E, a binary system that includes a classical infrared companion. We observed the DoAr 24E system with the Spitzer Infrared Spectrograph (IRS), with high-resolution, near-infrared spectroscopy of CO vibrational transitions, and with mid-infrared imaging. The source of high extinction toward infrared companions has been an item of continuing interest. Here we investigate the disk structure of DoAr 24E using the column densities, temperature, and velocity profiles of two CO absorption features seen toward DoAr 24Eb. We model the spectral energy distributions found using T-ReCS imaging and investigate the likely sources of extinction toward DoAr 24Eb. We find the lack of silicate absorption and small CO column density toward DoAr 24Eb suggest that the mid-infrared continuum is not as extinguished as the near-infrared, possibly due to the mid-infrared originating from an extended region. This, along with the velocity profile of the CO absorption, suggests that the source of high extinction is likely due to a disk or disk wind associated with DoAr 24Eb.

Optical and electrical characterization of an atmospheric pressure microplasma jet for Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures  

SciTech Connect

A rf microplasma jet working at atmospheric pressure has been characterized for Ar, He, and Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures. The microdischarge has a coaxial configuration, with a gap between the inner and outer electrodes of 250 {mu}m. The main flow runs through the gap of the coaxial structure, while the reactive gases are inserted through a capillary as inner electrode. The discharge is excited using a rf of 13.56 MHz, and rms voltages around 200-250 V and rms currents of 0.4-0.6 A are obtained. Electron densities around 8x10{sup 20} m{sup -3} and gas temperatures lower than 400 K have been measured using optical emission spectroscopy for main flows of 3 slm and inner capillary flows of 160 SCCM. By adjusting the flows, the flow pattern prevents the mixing of the reactive species with the ambient air in the discharge region, so that no traces of air are found even when the microplasma is operated in an open atmosphere. This is shown in Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} plasmas, where no CO and CN species are present and the optical emission spectroscopy spectra are mainly dominated by CH and C{sub 2} bands. The ratio of these two species follows different trends with the amount of precursor for Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures, showing the presence of distinct chemistries in each of them. In Ar/C{sub 2}H{sub 2} plasmas, CH{sub x} species are produced mainly by electron impact dissociation of C{sub 2}H{sub 2} molecules, and the CH{sub x}/C{sub 2}H{sub x} ratio is independent of the precursor amount. In Ar/CH{sub 4} mixtures, C{sub 2}H{sub x} species are formed mainly by recombination of CH{sub x} species through three-body reactions, so that the CH{sub x}/C{sub 2}H{sub x} ratio depends on the amount of CH{sub 4} present in the mixture. All these properties make our microplasma design of great interest for applications such as thin film growth or surface treatment.

Our measurement employed a high-efficiency gas counter, which was sensitive to positrons from both Ar-34 and its daughter Cl-34. We achieved the required precision on Ar-34 by analyzing the parent-daughter composite decay with a new fitting technique. We also obtained an improved half-life for Cl-34 of 1.5268(5) s, which has 0.03% precision and is a factor of two improvement on previous results.

Rovibrational spectroscopy of ArCO van der Waals complex  

SciTech Connect

The information that can be obtained from the high resolution rovibrational spectra of small molecular clusters is very useful for determining intermolecular potentials and the effects of intermolecular interactions on intramolecular bonds. Recently, such spectra have been obtained via absorption measurements using F-center, frequency difference and diode laser sources. Because F-center and frequency difference lasers operate best in the 2-4 ..mu..m region, studies using these laser sources have involved high frequency vibrational modes (H-X, X-C,F,Cl,Br) or overtones. Although diode lasers cover a much broader spectral range (3-20 ..mu..m), they are less convenient to use for doing survey spectroscopy. We have developed several new techniques which improve the sensitivity and convenience of absorption measurements using diode lasers for the study of molecular clusters in supersonic expansions. Here we describe these techniques and their application for the measurement of the rovibrational spectra of ArCO near 5 ..mu..m. 11 refs., 4 figs., 1 tab.

Data Packages in Hanford Site's Administrative Record (AR) and Public Information Repository (PIR)  

DOE Data Explorer (OSTI)

In 1989, the Department of Energy joined with the Washington State Department of Ecology and the U.S. Environmental Protection Agency in signing the Hanford Federal Facility Agreement and Consent Order more commonly known as the Tri-Party Agreement (TPA). The TPA outlines legally enforceable milestones for Hanford cleanup over the next several decades. The AR is the body of documents and information that is considered or relied upon to arrive at a final decision for remedial action or hazardous waste management. An AR is established for each operable unit (OU); treatment, storage, or disposal unit (TSD); or Expedited Response Action (ERA) group and will contain all documents having information considered in arriving at a Record of Decision or permit. Documents become part of the AR after they have been designated as an AR by the TPA or after EPA, DOE, or other official parties have identified a document or set of documents for inclusion. Furthermore, AR documents are to be kept in a Public Information Repository (PIR).Thousands of data packages that support the AR documents are available to the public in the Hanford PIR.

Traces on ion yields and electron spectra of Ar inner-shell hollow states with Free-Electron Lasers  

E-Print Network (OSTI)

We explore the formation by Free-Electron-Laser radiation of Ar hollow states with two or three inner-shell holes. We find that even charged Ar ion states can be more populated than odd charged Ar ion states. This depends on the pulse intensity and the number of energetically accessible inner- shell holes. Fully accounting for fine structure, we demonstrate that one electron spectra bare the imprints of Ar hollow states with two inner-shell holes. Moreover, we show how the Auger spectra of these hollow states can be extracted from two-electron coincidence spectra.

Simulation of an Ar/NH{sub 3} low pressure magnetized direct current discharge  

SciTech Connect

A two-dimensional fluid model has been used to investigate the properties of plasma in an Ar/NH{sub 3} low pressure magnetized direct current discharge. We compared the simulation results with the theoretical and experimental results of the other gas discharge in which the magnetic field is considered. Results that obtained using this method are in good agreement with literature. The simulation results show that the positive ammonia ion density follows the positive argon ion density. The Ar{sub 2}{sup +} density is slightly higher than the Ar{sup +} density at 100 mTorr. The largest ammonia ion is NH{sub 3}{sup +} ion, followed by NH{sub 2}{sup +}, NH{sub 4}{sup +}, and NH{sup +} ions. The contribution of NH{sup +} ions to the density of the positive ammonia ions is marginal. The influence of pressure on the plasma discharge has been studied by simulation, and the mechanisms have been discussed. The average plasma density increases as pressure increased. The plasma density appears to be more inhomogeneous than that at the lower pressure. The ratio of charge particles changed as pressure increased. The Ar{sup +} density is slightly higher than the Ar{sub 2}{sup +} density as the pressure increased. It makes NH{sub 4}{sup +} ratio increase as pressure increased. It shows that the electron temperature drops with rising pressure by numerical calculation.

Multiple ionization of Ar, Kr, and Xe in a superstrong laser field  

Science Journals Connector (OSTI)

We report the numerical calculation of Ar9+? Ar13+, Kr13+? Kr17+, and Xe19+? Xe23+ ion yield in the laser field with intensity exceeding 1019 W/cm2. The results of the calculations agree with the experimental data [K. Yamakava et al., Phys. Rev. A 68, 065403 (2003)] quantitatively (for the Ar ions) or qualitatively (for the Kr ions). The theoretical results disagree with the experimental data for the Xe ions. We discuss the possible influence of the relativistic effects on this disagreement between theory and experiment. We obtained the approximation formula for the position of the maximum ionic population with the given ionization multiplicity Z depending on the radiation intensity. This position is described by the power function of Z; the exponent is determined by the dependence of sequential ionization potentials on Z value. We discuss the dependence of the approximation formula parameters on the value of the FWHM of the laser pulse.

Ionization, charge exchange, and excitation in F + Ar and F + Kr collisions  

Science Journals Connector (OSTI)

We have measured projectile and target x-ray cross sections for F + Ar and F + Kr collisions using fluorine beams of charge states 7 +, 8 +, and 9+ with energies from 20 to 76 MeV. Pronounced enhancements for the Ar K and Kr L vacancy cross sections using F9+ ions compared to those for the 7+ projectile can be explained by charge exchange as described by an empirically scaled Brinkman-Kramers theory. The Ar L, Kr K and Kr M cross sections are found to exhibit features expected for Coulomb ionization. The projectile K x-ray production for the 9+ ion is accounted for by charge exchange processes. Predictions of the first Born approximation for direct single-step excitation to bound states by the target nucleus overestimate the observed cross sections for F7+ and F8+.

HIGH-RESOLUTION FOURIER TRANSFORM SPECTROSCOPY OF LANTHANUM IN Ar DISCHARGE IN THE NEAR-INFRARED  

SciTech Connect

A high-resolution spectrum of lanthanum has been recorded by a Fourier Transform spectrometer in the wavelength range from 833 nm to 1666 nm (6000 cm{sup 1} to 12,000 cm{sup 1}) using as light source a hollow cathode lamp operated with argon as the discharge carrier gas. In total, 2386 spectral lines were detected in this region, of which 555 lines could be classified as La I transitions and 10 lines as La II transitions. All La II transitions and 534 of these La I transitions were classified for the first time, and 6 of the La II transitions and 433 of the classified La I transitions appear to be new lines, which could not be found in the literature. The corresponding energy level data of classified lines are given. Additionally, 430 lines are assigned as Ar I lines and 394 as Ar II lines, of which 179 and 77, respectively, were classified for the first time. All 77 classified Ar II transitions as well as 159 of the classified Ar I transitions are new lines. Furthermore, the wavenumbers of 997 unclassified spectral lines were determined, 235 of which could be assigned as La lines, because of their hyperfine pattern. The remaining 762 lines may be either unclassified Ar lines or unresolved and unclassified La lines with only one symmetrical peak with an FWHM in the same order of magnitude as the Ar lines. The accuracy of the wavenumber for the classified lines with signal-to-noise-ratio higher than four is better than 0.006 cm{sup 1} which corresponds to an accuracy of 0.0004 nm at 830 nm and 0.0017 nm at 1660 nm, respectively.

Interactions between Ar projectiles and lead are studied in terms of global observables. The Streamer Chamber at the Berkeley BEVALAC was used to record all charged particles produced in collisions between 0.8 GeV/u Ar projectiles with a Pb/sub 3/O/sub 4/ target. A hardware trigger selected central collisions with Pb nuclei corresponding to a trigger cross section of 1 barn. In a geometrical picture this is equivalent to an impact parameter range of 0 to 5 fm.

Fenofibrate down-regulates the expressions of androgen receptor (AR) and AR target genes and induces oxidative stress in the prostate cancer cell line LNCaP  

SciTech Connect

Highlights: ? Fenofibrate induces cell cycle arrest in G1 phase and apoptosis in LNCaP cells. ? Fenofibrate reduces the expressions of androgen receptor in LNCaP cells. ? Fenofibrate induces oxidative stress in the prostate cancer cell line LNCaP. -- Abstract: Fenofibrate, a peroxisome proliferator-androgen receptor-alpha agonist, is widely used in treating different forms of hyperlipidemia and hypercholesterolemia. Recent reports have indicated that fenofibrate exerts anti-proliferative and pro-apoptotic properties. This study aims to investigate the effects of fenofibrate on the prostate cancer (PCa) cell line LNCaP. The effects of fenofibrate on LNCaP cells were evaluated by flow cytometry, reverse transcription-polymerase chain reaction, enzyme-linked immunosorbent assays, Western blot analysis, and dual-luciferase reporter assay. Fenofibrate induces cell cycle arrest in G1 phase and apoptosis in LNCaP cells, reduces the expressions of androgen receptor (AR) and AR target genes (prostate-specific antigen and TMPRSS2), and inhibits Akt phosphorylation. Fenofibrate can induce the accumulation of intracellular reactive oxygen species and malondialdehyde, and decrease the activities of total anti-oxidant and superoxide dismutase in LNCaP cells. Fenofibrate exerts an anti-proliferative property by inhibiting the expression of AR and induces apoptosis by causing oxidative stress. Therefore, our data suggest fenofibrate may have beneficial effects in fenofibrate users by preventing prostate cancer growth through inhibition of androgen activation and expression.

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

SciTech Connect

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.

Elastic scattering of intermediate-energy electrons by Ar and Kr  

Science Journals Connector (OSTI)

Using the relative-flow technique elastic differential cross sections ?? (Ar or Kr ) for Ar and Kr relative to ?? (He) have been measured at impact energies of 3, 5, 7.5, 10, 15, 20, 30, 50, 75, and 100 eV. The angular range covered is from 20 to 135. These ratios have been multiplied by the recently measured values of ??(He) to obtain ??(Ar or Kr ). The differential cross section curves for both Ar and Kr show deep minima. The positions of these minima have been obtained with an accuracy of 2. The cross sections in the angular regions lying between 0 and 20 and 135 and 180 could not be measured owing to instrumental limitations. In these regions estimates of the shapes of differential cross section (DCS) curves have been made by fitting the data obtained from 20 to 135 with a phase-shift analysis, while the normalization to the absolute scale was obtained by normalizing these fits to the relative flow measurements. From these estimates and the measured values of the differential cross section, integral and momentum-transfer cross sections have been obtained. The error limits for the differential, integral, and momentum-transfer cross sections have been estimated as 20, 30, and 30%, respectively.

Elastic Constants of Solid Ar, Kr, and Xe: A Monte Carlo Study  

Science Journals Connector (OSTI)

The elastic constants of classical systems of 108 particles arranged (with periodic boundary conditions) on an fcc lattice and interacting with pairwise-additive forces have been evaluated to an accuracy of about 2% by a Monte Carlo procedure closely related to that used by Hoover and his co-workers. For Ar(80 K) and Kr(85 and 115 K) we have used the Bobetic-Barker pair potentials and also included the corrections for the truncated tail of the pair potential, quantum effects, and three-body forces. For Ar(80 K) and Xe(156 K) we have carried out a similar calculation for the familiar Lennard-Jones 6:12 potential. Our 6:12 Ar(80 K) elastic constants agree well with the previous work of Hoover et al. but unfortunately differ only little from the more realistic Bobetic-Barker Ar(80 K) values. Bulk moduli for both potentials are compatible with the currently available experimental data. Comparison of our Kr results with experimental data indicates a need for refinement of the Bobetic-Barker Kr potential. The Xe(156 K) results agree very well with the recent Brillouin-scattering work of Gornall and Stoicheff which is to some extent disappointing because the same 6:12 potential is in poor agreement with the low-temperature heat capacity.

Prediction of Chinese coal ash fusion temperatures in Ar and H{sub 2} atmospheres  

SciTech Connect

The ash fusion temperatures (AFTs) of 21 typical Chinese coal ash samples and 60 synthetic ash samples were measured in Ar and H{sub 2} atmospheres. The computer software package FactSage was used to calculate the temperatures corresponding to different proportions of the liquid phase and predict the phase equilibria of synthetic ash samples. Empirical liquidus models were derived to correlate the AFTs under both Ar and H{sub 2} atmospheres of 60 synthetic ash samples, with their liquidus temperatures calculated by FactSage. These models were used to predict the AFTs of 21 Chinese coal ash samples in Ar and H{sub 2} atmospheres, and then the AFT differences between the atmospheres were analyzed. The results show that, for both atmospheres, there was an apparently linear correlation and good agreement between the AFTs of synthetic ash samples and the liquidus temperatures calculated by FactSage (R > 0.89, and {sigma} < 30{sup o}C). These models predict the AFTs of coal ash samples with a high level of accuracy (SE < 30{sup o}C). Because the iron oxides in coal ash samples fused under a H{sub 2} atmosphere are reduced to metallic iron and lead to changes of mineral species and micromorphology, the AFTs in a H{sub 2} atmosphere are always higher than those with an Ar atmosphere. 34 refs., 9 figs., 7 tabs.

Sudden Lifetime Drop Phenomena and their Effective Cures in PF-ring and PF-AR  

SciTech Connect

In PF-ring and PF-AR, sudden drops in the electron beam lifetime, which are attributed to dust trapping, were frequently observed after extensive renewals of the storage rings. The reduced-lifetime state sometimes lasts for a few hours, and the mitigation of this problem was strongly demanded for stable user operations. Since a major source of dust particles was thought to be a distributed ion pump (DIP), we attempted switching the DIPs off during user operations in both the rings. As a result, occurrence of the lifetime drops was almost completely suppressed during single-bunch mode in PF-ring, while the occurrence frequency was reduced by only 38% in PF-AR. We found that the lifetime drops were sometimes accompanied by a transient increase in the vacuum pressure at some discharge-prone devices. Based on the hypothesis that the harmful dust could be generated by an electric discharge in vacuum, we attempted the conditioning of these devices in PF-AR by storing 25% higher current than usual. By combination of the DIP-OFF operation and the high-current conditioning, the occurrence frequency of the lifetime drops in PF-AR was reduced by no less than 67%.

High multiplicity collisions of 1.2 GeV/nucleon /sup 40/Ar on Kcl and on BaI/sub 2/ in the Bevalac streamer chamber are studied using the global transverse momentum analysis introduced by Danielewicz and Odyniec. For both systems, there is a sideward flow which is significantly larger than intranuclear cascade model predictions. The current results permit a study of trends in the multiplicity, mass and energy dependence of the observed flow signatures. Estimates of the stiffness of the nuclear equation of state at high density are discussed.

The Deccan Trap CretaceousPaleogene boundary connection; new 40Ar/39Ar ages and critical assessment of existing argon data pertinent to this hypothesis  

Science Journals Connector (OSTI)

Abstract The CretaceousPaleogene boundary (KPgB) was dated by the 40Ar/39Ar method herein from the western interior of North America at 65.480.12Ma (1?), in good agreement with other recent published estimates. For the Deccan Traps, India, new argon ages as well as others available in the literature, are assessed for reliability based on (a) statistical reliability of plateau/isochron sections and (b) freshness of material dated utilizing the alteration index method. From tholeiitic lavas from the Composite Western Ghats Section (CWGS), only six ages are found to be reliable estimates of the time of crystallization. These ages along with the magnetic polarity of the lavas agree with the geomagnetic polarity time scale (GPTS) at ?6764Ma. Alkaline rocks from the Anjar area of Kutch, provide three reliable ages that suggest a hiatus in lava extrusion around KPgB. For the Rajahmundry basalts, the upper flows age defines its formation during chron 29n; a single age from the lower reversed polarity flow appears somewhat dichotomous when plotted against the GPTS. The reliable lava ages indicate the most voluminous (reversed polarity) sections of the CWGS were extruded at a time statistically indistinguishable from that of the KPgB. The Deccan Trap \\{KPgB\\} faunal extinction hypothesis remains plausible, but must compete with the latest report, favoring a very close temporal connection (?0.03m.y.) between the Chixculub (Impact) Crater and the KPgB.

Two-neutron knockout from neutron-deficient $^{34}$Ar, $^{30}$S, and $^{26}$Si  

E-Print Network (OSTI)

Two-neutron knockout reactions from nuclei in the proximity of the proton dripline have been studied using intermediate-energy beams of neutron-deficient $^{34}$Ar, $^{30}$S, and $^{26}$Si. The inclusive cross sections, and also the partial cross sections for the population of individual bound final states of the $^{32}$Ar, $^{28}$S and $^{24}$Si knockout residues, have been determined using the combination of particle and $\\gamma$-ray spectroscopy. Similar to the two-proton knockout mechanism on the neutron-rich side of the nuclear chart, these two-neutron removal reactions from already neutron-deficient nuclei are also shown to be consistent with a direct reaction mechanism.

Secondary ion emission from Si bombarded with large Ar cluster ions under UHV conditions  

Science Journals Connector (OSTI)

Si was bombarded with size-selected 40keV Ar cluster ions and positive secondary ions were measured using the time-of-flight technique under high and ultra-high vacuum (HV and UHV respectively) conditions. Si+ ions were main species detected under the incidence of 40keV Ar cluster ions, and the yields of Si cluster ions such as Si4+ were also extremely high under both conditions. On the other hand, oxidized secondary ions such as SiO+ were detected with high intensity only under the HV condition. The yield ratios of oxidized ions decreased in UHV to less than 1% of their values in HV. The effect of residual gas pressure on Si cluster ion yields is relatively low compared to oxidized ions, and the UHV condition is required to obtain accurate secondary ion yields.

The ArDM - a ton-scale liquid argon experiment for direct Dark Matter Detection  

SciTech Connect

The ArDM is a ton-scale double phase detector for the direct search of the Weakly Interacting Massive Particle (WIMPs) as Dark Matter candidates. The detector is based on a liquid Argon (LAr) target. The present goal is to assemble, fully characterize the detector on the surface and then operate it at an underground facility. The scintillation light and ionization charge produced by recoiling nuclei in WIMP-Ar collision can be measured independently. The discrimination of the WIMP induced nuclear recoils from the electron/gamma background is done using the pulse discrimination technique and the ratio between the produced light and charge. The experiment and the last results from the detector commissioning are presented.

Growth of Hydrogenated Amorphous Silicon Films by ArF Excimer Laser Photodissociation of Disilane  

Science Journals Connector (OSTI)

Hydrogenated amorphous silicon films have been grown on glass substrates by photodissociation of disilane using a pulsed ArF excimer laser foe the first time. Electrical and optical properties of the films have been examined. It was found that the magnitude of the gap energy of laser CVD films is rather large as compared to that of films obtained by a conventional plasma CVD. Preliminary examinations to control the conductivity by impurity doping have also been performed.

Adsorption of Kr, Xe, and Ar on highly uniform MgO smoke  

Science Journals Connector (OSTI)

The first atomic layer of Kr, Xe, and Ar adsorbed on MgO smoke is explored by using adsorption isotherms. A procedure has been developed by which we produce MgO smoke powders of higher homogeneity than previously reported. On these powders, apparent two-dimensional (2D) solid-vapor, fluid-vapor, and solid-fluid coexistence regions are observed for Kr and Xe. Triple-point temperatures are estimated to be 66.60.5 K and 100.81.0 K, and the critical temperatures are estimated to be 86.81.0 K and 1192.0 K, respectively, for these two elements. A comparison between Kr and Xe 2D-solid densities at the fluid-solid transition suggests that the 2D-solid phases are incommensurate with the substrate. The Ar isotherms are qualitatively different from those of Kr and Xe, showing no features corresponding to 2D phase transitions in the P-T range studied. A qualitative estimate places the Ar 2D critical temperature at about 65 K.

40Ar/39Ar dating of the Jiali and Gaoligong shear zones: Implications for crustal deformation around the Eastern Himalayan Syntaxis  

Science Journals Connector (OSTI)

We conducted a comprehensive 40Ar/39Ar geochronological study of the Jiali and Gaoligong shear zones to obtain a better understanding of crustal deformation and tectonic evolution around the Eastern Himalayan Syntaxis (EHS). The new age data reveal that the main phase of deformation in the Jiali and Gaoligong shear zones occurred from 22 to 11Ma and from 18 to 13Ma, respectively. Structural data collected during this study indicate that the Jiali shear zone underwent a change in shear sense from sinistral to dextral during its movement history. Based on a comparison with the deformation histories of other major shear zones in the region, we argue that the initial sinistral motion recorded by the Jiali shear zone was coincident with that of the Ailao ShanRed River shear zone, which marked the northern boundary of the southeastward extrusion of the Indochina block during the Early Miocene. From the Middle Miocene (?18Ma), the Jiali shear zone changed to dextral displacement, becoming linked with the dextral Gaoligong shear zone that developed as a consequence of continued northward indentation of the Indian continent into Asia. Since this time, the Jiali and Gaoligong shear zones have been united, defining the southwestern boundary of the EHS during clockwise rotation of the eastward-extruding Tibetan block, as revealed by recent GPS data. The temporal change in regional deformation pattern from southeastward block extrusion to clockwise rotation of crustal fragments may have played an important role in the development of the eastern Himalayan drainage system around the EHS.

Software Verification & Validation Report for the 244-AR Vault Interim Stabilization Ventilation System  

SciTech Connect

This document reports on the analysis, testing and conclusions of the software verification and validation for the 244-AR Vault Interim Stabilization ventilation system. Automation control system will use the Allen-Bradley software tools for programming and programmable logic controller (PLC) configuration. The 244-AR Interim Stabilization Ventilation System will be used to control the release of radioactive particles to the environment in the containment tent, located inside the canyon of the 244-AR facility, and to assist the waste stabilization efforts. The HVAC equipment, ducts, instruments, PLC hardware, the ladder logic executable software (documented code), and message display terminal are considered part of the temporary ventilation system. The system consists of a supply air skid, temporary ductwork (to distribute airflow), and two skid-mounted, 500-cfm exhausters connected to the east filter building and the vessel vent system. The Interim Stabilization Ventilation System is a temporary, portable ventilation system consisting of supply side and exhaust side. Air is supplied to the containment tent from an air supply skid. This skid contains a constant speed fan, a pre-filter, an electric heating coil, a cooling coil, and a constant flow device (CFD). The CFD uses a passive component that allows a constant flow of air to pass through the device. Air is drawn out of the containment tent, cells, and tanks by two 500-cfm exhauster skids running in parallel. These skids are equipped with fans, filters, stack, stack monitoring instrumentation, and a PLC for control. The 500CFM exhaust skids were fabricated and tested previously for saltwell pumping activities. The objective of the temporary ventilation system is to maintain a higher pressure to the containment tent, relative to the canyon and cell areas, to prevent contaminants from reaching the containment tent.

Mapping the Ionization State of Laser-Irradiated Ar Gas Jets With Multi-Wavelength Monochromatic X-Ray Imaging  

SciTech Connect

Two-dimensional monochromatic images of fast-electron stimulated Ar K{alpha} and He-{alpha} x-ray self-emission have recorded a time-integrated map of the extent of Ar{sup {approx}6+} and Ar{sup 16+} ions, respectively, within a high density (10{sup 20} cm{sup -3} atomic density) Ar plasma. This plasma was produced by irradiating a 2 mm wide clustering Ar gas jet with an ultra-high intensity (10{sup 19} W/cm{sup 2}, 200 fs) Ti:Sapphire laser operating at 800 nm. Spherically bent quartz crystals in the 200 (for K{alpha}) and 201 (for He-{alpha}) planes were used as near-normal incidence reflective x-ray optics. We see that a large (830 {micro}m long) region of plasma emits K{alpha} primarily along the laser axis, while the He-{alpha} emission is confined to smaller hot spot (230 {micro}m long) region that likely corresponds to the focal volume of the f/8 laser beam. X-ray spectra from a Bragg spectrometer operating in the von Hamos geometry, which images in one dimension, indicate that the centroids of the K{alpha} and He-{alpha} emission regions are separated by approximately 330 {micro}m along the laser axis.

Measurement of 37Ar to support technology for On-site Inspection under the Comprehensive Nuclear-Test-Ban Treaty  

E-Print Network (OSTI)

On-Site Inspection (OSI) is a key component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Measurements of radionuclide isotopes created by an underground nuclear explosion are a valuable signature of a Treaty violation. Argon-37 is produced from neutron interaction with calcium in soil, 40Ca(n,{\\alpha})37Ar. For OSI, the 35-day half-life of 37Ar provides both high specific activity and sufficient time for completion of an inspection before decay limits sensitivity. This paper presents a low-background internal-source gas proportional counter with an 37Ar measurement sensitivity level equivalent to 45.1 mBq/SCM in whole air.

Measurement of the Atomic Scattering Factor of Ne, Ar, Kr, and Xe  

Science Journals Connector (OSTI)

To test the accuracy of the Hartree-Fock (HF) method and the reliability of x-ray measurements of the atomic scattering factor f, we have determined the scattering of Mo K? radiation by Ne, Ar, Kr, and Xe gases. Values of f were obtained on an absolute basis with an accuracy of about %. Results at small angle yield the mean-square radius of the electron cloud ?r2?av and the dispersion correction. For Ne, Ar, and Kr, the values of ?r2?av are in good agreement with HF calculations. For Xe, the experimental value is significantly lower. Susceptibility results yield about 6% lower values in each case. Our derived values of the dispersion correction are each more negative than those obtained from published absorption coefficients. At higher angles, our f values differ by less than 0.2 electron unit from the HF values for all the gases; even for Xe the approximate HF values presently available are more nearly accurate than the Thomas-Fermi-Dirac (TFD) values. We conclude that a 4% discrepancy between theory and experiment found by Batterman, Chipman, and DeMarco for metal powders arose from solid-state effects or from difficulties in sample preparation.

Hole transport in the rare-gas solids Ne, Ar, Kr, and Xe  

Science Journals Connector (OSTI)

This paper reports an investigation of the drift mobility of excess holes in solid Ne, Ar, Kr, and Xe. Thin-crystal specimens (50-500 ?m thick) were grown from the liquid between parallel-plate electrodes in a chamber attached to a miniature cryostat after purification of the starting gas. As in previous work on the electron transport in rare-gas solids and liquids, an electron-beam technique was used to generate excess carriers near one of the electrodes. Holes were extracted by the applied field and their transit time was measured directly, leading to the drift mobility ?h. Close to the triple points, ?h values in the above crystals lie between 1 10-2 and 4 10-2 cm2 V-1 sec-1, several orders of magnitude lower than the corresponding electron mobilities. The form of the temperature dependence of ?h changes progressively from Xe(?h?T-1.6) to an essentially activated mobility in Ar and Ne. The experimental results have been analyzed in terms of small-polaron theory, using both the adiabatic and nonadiabatic approximations. The theory can account for the different forms of the temperature dependence and possible ranges of values for the predominant phonon energy, the polaron binding energy and the transfer energy for holes have been deduced in each case. These quantities, characterizing the hole hopping transport, vary systematically from Xe to Ne and their correlation is discussed in some detail.

Mutual diffusion in binary Ar-Kr mixtures and empirical diffusion models  

Science Journals Connector (OSTI)

Molecular dynamics simulations of four binary Ar-Kr mixtures are used to compute self- and mutual-diffusion coefficients. Results using mean squared displacements and using velocity correlation functions are presented. The diffusivity coefficients are also presented in the time and frequency domains where a comparatively low frequency structure is evident in some simulations. The computed diffusivities are dependent on the maximum time over which the velocity correlation functions are integrated and the time at which the Einstein relationships are evaluated. This dependence explains in part the small systematic differences between our results (2080 ps) and earlier molecular dynamics results (<4 ps) in the system Ar-Kr. We compare the computed mutual diffusion coefficients to two empirical models, Darkens model and the common force model. Darkens model is consistent with our results over the entire frequency range we resolve. At frequencies lower than about 5 ps-1 Darkens model and the common force model converge and we cannot discriminate between them. At higher frequencies the common force model prediction is significantly different from the computed mutual diffusion coefficient. Assumptions regarding the contribution of cross correlations that are implicit in the empirical models are discussed and tested against our simulation results. The net contribution of velocity cross correlations is found to be negligible, as is often assumed in deriving Darkens model, but the individual cross-correlation terms are substantial and negativea finding contrary to common assumptions. 1996 The American Physical Society.

Negative ion motion in the mixtures of SF6 with CF4 and CH4-Ar  

Science Journals Connector (OSTI)

This paper deals with the measurement of the mobility of negative ions in the mixtures of SF6 with CF4 and the CH4-Ar (50:50) binary mixture with SF6 contents up to 50%. The pulsed Townsend technique was used to observe the integrated ionic avalanches over a range of the density-reduced electric field E/N for which ionization is either negligible or absent, and attachment processes are significant, leading to the formation of mostly SF6-. The E/N range of measurement was from 1 to 70 Td (1 Td=10-17 V cm2), over which the measured mobilities were found to be almost constant. The mobility of the negative ions was also measured for trace amounts of SF6 in CH4 and Ar and 1% CF4, thereby providing a good value of the mobility of SF6- in these pure gases, in order to test the measured mobilities with Blancs law.

Determination of the thermal neutron induced 41Ca(n,p)41K and 41Ca(n,?)38Ar reaction cross sections  

Science Journals Connector (OSTI)

The 41Ca(n,p)41K and 41Ca(n,?)38Ar reaction cross sections were determined with thermal neutrons at the high flux reactor of the ILL in Grenoble. For the 41Ca(nth,p)41K reaction cross section, a value of (72)?mb was obtained. In the case of the 41Ca(nth,?)38Ar reaction, the transition to the ground state in 38Ar has a cross section ?(nth,?0)?=?(426)?mb, the most prominent decay going to the first excited state in 38Ar with a cross section ?(nth,?1)?=?(13025)?mb. This can be explained by the presence of a nearby bound level with J?=4-. Also 41Ca(nth,??)38Ar transitions have been observed with a cross section of (102)?mb. The primary ? transitions are shown to have a M1 multipolarity.

AR-NE3A, a New Macromolecular Crystallography Beamline for Pharmaceutical Applications at the Photon Factory  

SciTech Connect

Recent advances in high-throughput techniques for macromolecular crystallography have highlighted the importance of structure-based drug design (SBDD), and the demand for synchrotron use by pharmaceutical researchers has increased. Thus, in collaboration with Astellas Pharma Inc., we have constructed a new high-throughput macromolecular crystallography beamline, AR-NE3A, which is dedicated to SBDD. At AR-NE3A, a photon flux up to three times higher than those at existing high-throughput beams at the Photon Factory, AR-NW12A and BL-5A, can be realized at the same sample positions. Installed in the experimental hutch are a high-precision diffractometer, fast-readout, high-gain CCD detector, and sample exchange robot capable of handling more than two hundred cryo-cooled samples stored in a Dewar. To facilitate high-throughput data collection required for pharmaceutical research, fully automated data collection and processing systems have been developed. Thus, sample exchange, centering, data collection, and data processing are automatically carried out based on the user's pre-defined schedule. Although Astellas Pharma Inc. has a priority access to AR-NE3A, the remaining beam time is allocated to general academic and other industrial users.

Ionization of the He, Ne, Ar, Kr, and Xe isoelectronic series by proton impact  

Science Journals Connector (OSTI)

In this paper we report ionization cross sections of positive Li+, Na+, K+, Rb+, neutral He, Ne, Ar, Kr, Xe, and negative F?, Cl?, Br?, I? ions by impact of protons with energies ranging from 25to1000keV. Cross sections of singly charged ions are relevant to the calculation of electron yields in collisions with insulator surfaces. Calculations were performed within the continuum distorted waveeikonal initial state method using an angular expansion in spherical harmonics and a numerical evaluation of the radial functions corresponding to both the initial (bound) and the final (continuum) states. The first Born approximation was used on an equal footing. We find that this first-order theory holds for proton energies larger than 300keV. For comparison, we also calculate the shellwise local plasma approximation. Our results show that it gives a good account of the cross sections for neutral targets.

Preliminary Investigation of the Thermal Decomposition of Ablefoam and EF-AR20 Foam (Ablefoam Replacement)  

SciTech Connect

Preliminary thermal decomposition experiments with Ablefoam and EF-AR20 foam (Ablefoam replacement) were done to determine the important chemical and associated physical phenomena that should be investigated to develop the foam decomposition chemistry sub-models that are required in numerical simulations of the fire-induced response of foam-filled engineered systems for nuclear safety applications. Although the two epoxy foams are physically and chemically similar, the thermal decomposition of each foam involves different chemical mechanisms, and the associated physical behavior of the foams, particularly ''foaming'' and ''liquefaction,'' have significant implications for modeling. A simplified decomposition chemistry sub-model is suggested that, subject to certain caveats, may be appropriate for ''scoping-type'' calculations.

Interatomic decay of inner-valence ionized states in ArXe clusters: Relativistic approach  

SciTech Connect

In this work we investigate interatomic electronic decay processes taking place in mixed argon-xenon clusters upon the inner-valence ionization of an argon center. We demonstrate that both interatomic Coulombic decay and electron-transfer mediated decay (ETMD) are important in larger rare gas clusters as opposed to dimers. Calculated secondary electron spectra are shown to depend strongly on the spin-orbit coupling in the final states of the decay as well as the presence of polarizable environment. It follows from our calculations that ETMD is a pure interface process taking place between the argon-xenon layers. The interplay of all these effects is investigated in order to arrive at a suitable physical model for the decay of inner-valence vacancies taking place in mixed ArXe clusters.

Collective flow in Ar+KCl at 1. 8 GeV/nucleon  

SciTech Connect

The failure of the standard sphericity tensor analysis to detect any significant collective flow effect in Ar+KCl at 1.8A GeV is examined in light of the success of the transverse momentum analysis technique suggested by Danielewicz and Odyniec in exhibiting collective flow in the same system. It is argued, using a simple estimate which takes into consideration the main features of the data, that the failure of the sphericity analysis is attributable to the dominant contribution of the longitudinal momentum of the spectators which has nothing to do with the collective effects for which sphericity analysis is designed. The exclusion of the spectators from the sphericity tensor leads to a clear signal from the collective transverse flow of the participants whenever such a flow takes place.

Shell-Model Analysis of the Level Structure of Ar41  

Science Journals Connector (OSTI)

Levels of Ar41 experimentally observed up to excitation energy of 4.5 MeV are considered. Using experimental data from neighboring nuclei the positions of 40 odd-parity states are calculated in the framework of the shell model. Good agreement is obtained for the low-lying levels. Approximate treatment of the d322f722p32 and d322f722p12 configurations in addition to the d322f723 ground configuration gives a semi-quantitative account of all odd parity 3/2 and 1/2 levels up to 4.5 MeV. Many odd-parity levels with J>32 which were not yet found experimentally are predicted to be in this region.

Angular distribution of ejected electrons in resonant Auger processes of Ar, Kr, and Xe  

Science Journals Connector (OSTI)

Angle-resolved electron spectroscopy with the help of synchrotron radiation has been used to study resonant Auger processes near the core shells of Ar 2p, Kr 3d, and Xe 4d. Results for the lowest-energy resonances have received special attention: argon (Ar 2p3/2?4s) at a photon energy of 244.4 eV, krypton (Kr 3d5/2?5p) at 91.2 eV, and xenon (Xe 4d5/2?6p) at 65.1 eV. The angular distribution parameters ? are evaluated for each of the resolved Auger peaks. Most striking is the occurrence of large negative ? values for some of the higher kinetic energy peaks. The results are most apparent under high electron resolution. The theoretical basis for having ? values near -1 is discussed. In particular, the experimental results for argon are found to be in general agreement with the prediction of -1 ? values by using either angular momentum transfer theory or normal Auger theory. However, a better understanding of the range of ? values will have to await explicit calculations. Experimental results on the Auger spectra are also given at lower kinetic energies, for shakeup states, and for higher-energy resonances, especially those involving vacancies in the core shells of the lower spin states. It is shown that, although transitions having the same final state of the singly charged ion frequently have similar relative intensities and ? values, occasionally they differ quite markedly. The theoretical consequences of variant behavior for processes having the same final states are also discussed.

Aging tests of the proportional wire chambers using Ar/CF4/CH4 (74:20:6), Ar/CF4/CH4 (67:30:3), Ar/CF4/CO2 (65:30:5) mixtures for the HERA-B Muon Detector  

E-Print Network (OSTI)

The Muon Detector of the HERA-B experiment at DESY is a gaseous detector that provides muon identification in a high-rate hadronic environment. We present our studies on the properties of several fast gases, Ar/CF4/CH4 (74:20:6), Ar/CF4/CH4 (67:30:3) and Ar/CF4/CO2 (65:30:5), which have been found to fulfill muon detection requirements. The severe radiation environment of the HERA-B experiment leads to the maximum charge deposit on a wire, within the muon detector, of 200 mC/cm per year. For operation in such an environment, the main criteria for the choice of gas turned out to be stability against aging. An overview of aging results from laboratory setups and experimental detectors for binary and ternary mixtures of Ar, CH4, CF4 and CO2 is presented and the relevance of the various aging results is discussed. Since it is not clear how to extrapolate aging results from small to large areas of irradiation, the lifetime of aluminum proportional chambers was studied under various conditions. In this paper we provide evidence that aging results depend not only upon the total collected charge. It was found that the aging rate for irradiation with $Fe^{55}$ X-rays and 100 MeV $\\alpha$-particles may differ by more than two orders of magnitude.

Androgen receptor (AR) positive vs negative roles in prostate cancer cell deaths including apoptosis, anoikis, entosis, necrosis and autophagic cell death  

Science Journals Connector (OSTI)

Abstract Androgen/androgen receptor (AR) signaling plays pivotal roles in the prostate development and homeostasis as well as in the progression of prostate cancer (PCa). Androgen deprivation therapy (ADT) with anti-androgens remains as the main treatment for later stage PCa, and it has been shown to effectively suppress \\{PCa\\} growth during the first 1224months. However, ADT eventually fails and tumors may re-grow and progress into the castration resistant stage. Recent reports revealed that AR might play complicated and even opposite roles in \\{PCa\\} progression that might depend on cell types and tumor stages. Importantly, AR may influence \\{PCa\\} progression via differential modulation of various cell deaths including apoptosis, anoikis, entosis, necrosis, and autophagic cell deaths. Targeting AR may induce \\{PCa\\} cell apoptosis, autophagic cell deaths and programmed necrosis, yet targeting AR may suppress cell deaths via anoikis and entosis that may potentially lead to increased metastasis. These differential functions of AR in various types of \\{PCa\\} cell death might challenge the current ADT with anti-androgens treatment. Further detailed dissection of molecular mechanisms by which AR modulates different \\{PCa\\} cell deaths will help us to develop a better therapy to battle PCa.

High-resolution study of {sup 37}Cl{yields}{sup 37}Ar Gamow-Teller transition via {sup 37}Cl({sup 3}He, t){sup 37}Ar reaction  

SciTech Connect

We performed a {sup 37}Cl({sup 3}He, t){sup 37}Ar experiment at E = 140 MeV/nucleon and 0 deg. with a resolution of 30 keV. The Gamow-Teller (GT) strength distribution was obtained up to the excitation energy (E{sub x}) of 14.2 MeV in {sup 37}Ar. Under the assumption of isospin symmetry, the GT strengths in the {sup 37}Cl{yields}{sup 37}Ar and {sup 37}Ca{yields}{sup 37}K transitions are analogous. The obtained strength distribution was compared with the mirror {sup 37}Ca{beta} decay up to E{sub x} = 8.6 MeV. The overall shapes of the distributions were similar, but the details were not necessary the same. In order to understand those differences, the experimental distribution was compared with the shell model (SM) calculation using the USD interaction. The SM calculation suggests that differences at lower energies can be caused by a large tensor contribution in the charge-exchange reaction. On the other hand, the differences seen at higher energies are due to the breaking of the mirror symmetry. The neutrino cross section for the {sup 8}B solar neutrino source was calculated using the obtained data.

Intentional reconstruction of silicon network on the surface and within sub-surface by H and Ar  

SciTech Connect

Silicon thin films were prepared by Chemical Annealing where the deposition of thin layer (<3 nm thick) by RF glow discharge of SiH{sub 4} and the treatment with hydrogen atoms (H) or triplet state of argon ({sup 3}Ar) were repeated alternating. Consequently, wide gap a-Si:H with the gap of 2.1 eV was made by H-treatment at rather low substrate temperature (Ts<150 C), while a-Si:H with the gap narrower than 1.6 eV was obtained by the treatment with {sup 3}Ar at high Ts(>300 C), resulting from the release of excessive hydrogen. Both the wider or the narrower gap films exhibited low defect density lower than 10{sup 16} cm{sup {minus}3} and obvious improvements in the stability for light soaking.

Dry etching properties of TiO2 thin films in O2/CF4/Ar plasma  

Science Journals Connector (OSTI)

In this work, the etching properties of titanium dioxide (TiO2) thin film in additions of O2 at CF4/Ar plasma were investigated. The maximum etch rate of 179.4nm/min and selectivity of TiO2 of 0.6 were obtained at an O2/CF4/Ar (=3:16:4sccm) gas mixing ratio. In addition, the etch rate and selectivity were measured as a function of the etching parameters, such as the RF power, DC-bias voltage, and process pressure. The efficient destruction of the oxide bonds by ion bombardment, which was produced from the chemical reaction of the etched TiO2 thin film, was investigated by X-ray photoelectron spectroscopy. To determine the re-deposition of sputter products and reorganization of such residues on the surface, the surface roughness of TiO2 thin film were examined using atomic force microscopy.

Behavior of the Cross Sections for Polonium Production in Nuclear Reactions of Ar40 with Dy104  

Science Journals Connector (OSTI)

Excitation functions are reported for the reactions of Dy164 with Ar40 to produce Po200 and Po199. The cross sections are much smaller than the calculated values and it is concluded that this is due to an angular momentum cutoff and to a large fission width. The reaction threshold at a laboratory energy of 4.2 MeV per nucleon indicates a low Coulomb barrier (r0=1.45 fm).

One-Electron Theory of the Bulk Properties of Crystalline Ar, Kr, and Xe  

Science Journals Connector (OSTI)

The cohesive energy as a function of lattice constant and the P-V relation for Ar, Kr, and Xe have been calculated at T=0 K in the static-lattice limit. The calculation employed the self-consistent augmented-plane-wave statistical-exchange (APW-X?) method, which, except for our own preliminary work, has not heretofore been applied to the study of the bulk properties of a van der Waals crystal. The agreement with experiment is at least semiquantitative with respect to the cohesive energies. The comparison with extant PV data is acceptable. By use of a static-lattice sum of a pair-potential function with undetermined parameters, an effective pair potential is determined, with fairly realistic parameter values as a result. Comparison with other energy-band calculations shows that the occupied one-electron energies found in this calculation are in good agreement with those found by other workers. The conduction-band energies are not a result that is usual in X? calculations. The over-all trends found in this calculation are related to those found by Averill in a recent APW-X? calculation on the alkali metals.

Crystallization phase transition in the precursors of CIGS films byAr-ion plasma etching process  

Science Journals Connector (OSTI)

Abstract Mixed alloy CuInGa precursors were deposited from CuGa alloy and Indium targets by the DC magnetron co-sputtering method. There were four crystallization phases, In, CuIn2, Cu11In9 and Cu3Ga, identified in the precursor after deposition. A large grain-size CIGS film was achieved by controlling the annealing period for selenization and utilizing a two-stage selenization process for secondary crystallization during rapid thermal annealing process. As the annealing temperature increased, the phase transitions moved toward the Cu-rich inter-metallic phases. In addition, the phase transition, stoichiometric ratio and surface-morphology were modified by Ar-ion plasma etching process of the precursors. The results show that after the ion etching process, the precursors can be transferred into a single Cu11In9 crystallization phase and the number of crevices increased due to the soft texture of indium on the surface of the precursors. Finally, CIGS films with good crystalline properties were achieved after a suitable selenization process of only 1-stage.

Improved volatile fatty acid and biomethane production from lipid removed microalgal residue (LR?AR) through pretreatment  

Science Journals Connector (OSTI)

Abstract Renewable energy from lipid removed microalgal residues (LR?ARs) serves as a promising tool for sustainable development of the microalgal biodiesel industry. Hence, in this study, LR?AR from Ettlia sp. was characterized for its physico-biochemical parameters, and applied to various pretreatment to increase the biodegradability and used in batch experiments for the production of volatile fatty acids (VFA) and biomethane. After various pretreatments, the soluble organic matters were increased at a maximum of 82% in total organic matters in alkali-autoclaved sample. In addition, VFA and methane production was enhanced by 30% and 40% in alkali-sonicated and alkali-autoclaved samples, respectively. Methane heating value was recovered at maximum of 6.6MJkg?1VS in alkali-autoclaved conditions with comparison to non-pretreated samples. The pretreatment remarkably improved LR?AR solubilization and enhanced VFA and biomethane production, which holds immense potential to eventually reduce the cost of algal biodiesel.

Ion-radical synergy in HfO{sub 2} etching studied with a XeF{sub 2}/Ar{sup +} beam setup  

SciTech Connect

To gain more insight into fundamental aspects of the etching behavior of Hf-based high-k materials in plasma etch reactors, HfO{sub 2} films were etched in a multiple-beam setup consisting of a low energy Ar{sup +} ion beam and a XeF{sub 2} radical beam. The etch rate and etch products were monitored by real-time ellipsometry and mass spectrometry, respectively. Although etching of HfO{sub 2} in XeF{sub 2}/Ar{sup +} chemistry is mainly a physical effect, an unambiguous proof of the ion-radical synergistic effect for the etching of HfO{sub 2} is presented. The etch yield for 400 eV Ar{sup +} ions at a substrate temperature of 300 deg. C was 0.3 atoms/ion for Ar{sup +} sputtering and increased to 2 atoms/ion when XeF{sub 2} was also supplied. The etch yield proved to follow the common square root of ion energy dependence both for pure sputtering and radical enhanced etching, with a threshold energy at room temperature of 69{+-}17 eV for Ar{sup +} ions and 54{+-}14 eV for Ar{sup +} ions with XeF{sub 2}.

THE KINEMATICS AND PLASMA PROPERTIES OF A SOLAR SURGE TRIGGERED BY CHROMOSPHERIC ACTIVITY IN AR11271  

SciTech Connect

We observe a solar surge in NOAA AR11271 using the Solar Dynamics Observatory (SDO) Atmospheric Imaging Assembly 304 A image data on 2011 August 25. The surge rises vertically from its origin up to a height of Almost-Equal-To 65 Mm with a terminal velocity of Almost-Equal-To 100 km s{sup -1}, and thereafter falls and fades gradually. The total lifetime of the surge was Almost-Equal-To 20 minutes. We also measure the temperature and density distribution of the observed surge during its maximum rise and find an average temperature and a density of 2.0 MK and 4.1 Multiplication-Sign 10{sup 9} cm{sup -3}, respectively. The temperature map shows the expansion and mixing of cool plasma lagging behind the hot coronal plasma along the surge. Because SDO/HMI temporal image data do not show any detectable evidence of significant photospheric magnetic field cancellation for the formation of the observed surge, we infer that it is probably driven by magnetic-reconnection-generated thermal energy in the lower chromosphere. The radiance (and thus the mass density) oscillations near the base of the surge are also evident, which may be the most likely signature of its formation by a reconnection-generated pulse. In support of the present observational baseline of the triggering of the surge due to chromospheric heating, we devise a numerical model with conceivable implementation of the VAL-C atmosphere and a thermal pulse as an initial trigger. We find that the pulse steepens into a slow shock at higher altitudes which triggers plasma perturbations exhibiting the observed features of the surge, e.g., terminal velocity, height, width, lifetime, and heated fine structures near its base.

Surface engineering of a Zr-based bulk metallic glass with low energy Ar- or Ca-ion implantation  

Science Journals Connector (OSTI)

Abstract In the present study, low energy ion implantation was employed to engineer the surface of a Zr-based bulk metallic glass (BMG), aiming at improving the biocompatibility and imparting bioactivity to the surface. Ca- or Ar-ions were implanted at 10 or 50keV at a fluence of 8נ1015ions/cm2 to (Zr0.55Al0.10Ni0.05Cu0.30)99Y1 (at.%) BMG. The effects of ion implantation on material properties and subsequent cellular responses were investigated. Both Ar- and Ca-ion implantations were suggested to induce atom displacements on the surfaces according to the Monte-Carlo simulation. The change of atomic environment of Zr in the surface regions as implied by the alteration in X-ray absorption measurements at Zr K-edge. X-ray photoelectron spectroscopy revealed that the ion implantation process has modified the surface chemical compositions and indicated the presence of Ca after Ca-ion implantation. The surface nanohardness has been enhanced by implantation of either ion species, with Ca-ion implantation showing more prominent effect. The BMG surfaces were altered to be more hydrophobic after ion implantation, which can be attributed to the reduced amount of hydroxyl groups on the implanted surfaces. Higher numbers of adherent cells were found on Ar- and Ca-ion implanted samples, while more pronounced cell adhesion was observed on Ca-ion implanted substrates. The low energy ion implantation resulted in concurrent modifications in atomic structure, nanohardness, surface chemistry, hydrophobicity, and cell behavior on the surface of the Zr-based BMG, which were proposed to be mutually correlated with each other.

Measurement of Complex Fragments and Clues to the Entropy Production from 42-137-MeV/nucleon Ar + Au  

Science Journals Connector (OSTI)

Intermediate-rapidity fragments with A=1-14 emitted from 42-137-MeV/nucleon Ar + Au have been measured. Evidence is presented that these fragments arise from a common moving source. Entropy values are extracted from the mass distributions by use of quantum statistical and Hauser-Feshbach theories. The extracted entropy values of SA?2-2.4 are much smaller than the values expected from measured deuteron-to-proton ratios, but are still considerably higher than theoretically predicted values.

Reply to "Isotropy of Speed of Light" by Castano and Hawkins, arXiv:1103.1620  

E-Print Network (OSTI)

In "Isotropy of Speed of Light" by Castano and Hawkins, arXiv:1103.1620, it is claimed, using a flawed theoretical argument, that the speed of light must necessarily be isotropic, independent even of experiment. The key false assumption made is that the round trip time must always be invariant wrt change of direction of the light path. This is shown to be false. More importantly the anisotropy of the speed of light has been repeatedly detected in experiments, beginning with Michelson and Morley in 1887, and with the most recent data being from spacecraft earth-flyby Doppler shift data. Similar misunderstandings critically affect the designs for LIGO and LISA.

An international land-biosphere model benchmarking activity for the IPCC Fifth Assessment Report (AR5)  

SciTech Connect

The need to capture important climate feedbacks in general circulation models (GCMs) has resulted in efforts to include atmospheric chemistry and land and ocean biogeochemistry into the next generation of production climate models, called Earth System Models (ESMs). While many terrestrial and ocean carbon models have been coupled to GCMs, recent work has shown that such models can yield a wide range of results (Friedlingstein et al., 2006). This work suggests that a more rigorous set of global offline and partially coupled experiments, along with detailed analyses of processes and comparisons with measurements, are needed. The Carbon-Land Model Intercomparison Project (C-LAMP) was designed to meet this need by providing a simulation protocol and model performance metrics based upon comparisons against best-available satellite- and ground-based measurements (Hoffman et al., 2007). Recently, a similar effort in Europe, called the International Land Model Benchmark (ILAMB) Project, was begun to assess the performance of European land surface models. These two projects will now serve as prototypes for a proposed international land-biosphere model benchmarking activity for those models participating in the IPCC Fifth Assessment Report (AR5). Initially used for model validation for terrestrial biogeochemistry models in the NCAR Community Land Model (CLM), C-LAMP incorporates a simulation protocol for both offline and partially coupled simulations using a prescribed historical trajectory of atmospheric CO2 concentrations. Models are confronted with data through comparisons against AmeriFlux site measurements, MODIS satellite observations, NOAA Globalview flask records, TRANSCOM inversions, and Free Air CO2 Enrichment (FACE) site measurements. Both sets of experiments have been performed using two different terrestrial biogeochemistry modules coupled to the CLM version 3 in the Community Climate System Model version 3 (CCSM3): the CASA model of Fung, et al., and the carbon-nitrogen (CN) model of Thornton. Comparisons of the CLM3 offline results against observational datasets have been performed and are described in Randerson et al. (2009). CLM version 4 has been evaluated using C-LAMP, showing improvement in many of the metrics. Efforts are now underway to initiate a Nitrogen-Land Model Intercomparison Project (N-LAMP) to better constrain the effects of the nitrogen cycle in biosphere models. Presented will be new results from C-LAMP for CLM4, initial N-LAMP developments, and the proposed land-biosphere model benchmarking activity.

TWO TYPES OF EXTREME-ULTRAVIOLET BRIGHTENINGS IN AR 10926 OBSERVED BY HINODE/EIS  

SciTech Connect

We have investigated seven extreme-ultraviolet (EUV) brightenings in the active region AR 10926 on 2006 December 2 observed by the EUV Imaging Spectrometer on board the Hinode spacecraft. We have determined their Doppler velocities and non-thermal velocities from 15 EUV spectral lines (log T = 4.7 - 6.4) by fitting each line profile to a Gaussian function. The Doppler velocity maps for different temperatures are presented to show the height dependence of the Doppler shifts. It is found that the active region brightenings show two distinct Doppler shift patterns. The type 1 brightening shows a systematic increase of Doppler velocity from -68 km s{sup -1} (strong blueshift) at log T = 4.7 to -2 km s{sup -1} (weak blueshift) at log T = 6.4, while the type 2 brightenings have Doppler velocities in the range from -20 km s{sup -1} to 20 km s{sup -1}. The type 1 brightening point is considered to sit in an upward reconnection outflow whose speed decreases with height. In both types of brightenings, the non-thermal velocity is found to be significantly enhanced at log T = 5.8 compared to the background region. We have also determined electron densities from line ratios and derived temperatures from emission measure loci using the CHIANTI atomic database. The electron densities of all brightenings are comparable to typical values in active regions (log N{sub e} = 9.9-10.4). The emission measure loci plots indicate that these brightenings should be multi-thermal whereas the background is isothermal. The differential emission measure as a function of temperature shows multiple peaks in the EUV brightening regions, while it has only a single peak (log T = 6.0) in the background region. Using Michelson Doppler Imager magnetograms, we have found that the type 1 brightening is associated with a canceling magnetic feature with a flux canceling rate of 2.4 x 10{sup 18} Mx hr{sup -1}. We also found the canceling magnetic feature and chromospheric brightenings in the type 1 brightening from the Hinode SOT and Transition Region and Coronal Explorer data. This observation corroborates our argument that brightening is caused by magnetic reconnection in a low atmosphere.

Detection of the primary scintillation light from dense Ar, Kr and Xe with novel photosensitive gaseous detectors  

E-Print Network (OSTI)

The detection of primary scintillation light in combination with the charge or secondary scintillation signals is an efficient technique to determine the events t=0 as well as particle / photon separation in large mass TPC detectors filled with noble gases and/or condensed noble gases. The aim of this work is to demonstrate that costly photo-multipliers could be replaced by cheap novel photosensitive gaseous detectors: wire counters, GEMs or glass capillary tubes coupled with CsI photocathodes. We have performed systematic measurements with Ar, Kr and Xe gas at pressures in the range of 1-50 atm as well as some preliminary measurements with liquid Xe and liquid Ar. With the gaseous detectors we succeeded in detecting scintillation light produced by 22 keV X-rays with an efficiency of close to 100%. We also detected the scintillation light produced by bs (5 keV deposit energy) with an efficiency close to 25%. Successful detection of scintillation from 22 keV gammas open new experimental possibilities not only ...

Determination of the non-relaxation (reflection) probability of metastable Ar(3P2) atoms on a Pyrex surface  

Science Journals Connector (OSTI)

Two techniques allowing us to measure the probability for the non-relaxation of metastable atoms impinging on glass surfaces are presented. In the first one, the radial distribution of Ar*(3P2) metastable atoms in the proximity of the glass wall is determined by a resonant absorption technique in the afterglow of a low pressure (8.5?Pa) argon discharge. The comparison of the experimental density profile with model profiles predicted by a simple model, permits the determination of an upper limit, R ? 0.45, for the non-relaxation probability. In the second experiment, the Doppler-shifted laser-induced fluorescence technique is used to deduce the velocity distribution function of Ar*(3P2) metastable atoms in the vicinity of a Pyrex wall in very low pressure (0.090.5?Pa) argon plasmas. The non-relaxation probability is deduced from the ratio of the flux of metastable atoms having their radial velocity oriented towards the cell axis to the flux of those with their radial velocity oriented towards the wall. This latter technique is much more precise and gives a value of R = 0.28 0.05 for the non-relaxation probability. It is also shown that metastable atoms moving away from the surface have somehow been accommodated to the surface and acquired a velocity distribution corresponding to the wall temperature.

Development of the sputtering yields of ArF photoresist after the onset of argon ion bombardment  

SciTech Connect

Modification of an advanced ArF excimer lithographic photoresist by 400 eV Ar ion irradiation was observed in situ in real time using both infrared spectroscopy and a quartz microbalance sensor. The photoresist sputtering yields had a characteristic behavior; the sputtering yields were higher than unity at the beginning, until an ion dose of 2 Multiplication-Sign 10{sup 16} ions cm{sup -2}. Thereafter, the yields decreased immediately to almost zero and remained constant with the yield at zero until a dose of approximately 4 Multiplication-Sign 10{sup 16} ions cm{sup -2} was reached. At larger doses, the yields increased again and reached a steady-state value of approximately 0.6. This development of the sputtering yield after the onset of ion bombardment is explained by an ion-induced modification of the photoresist that includes preferential sputtering of individual groups, argon ion implantation and the generation of voids. All these effects must be taken into account to assess line-edge-roughness on a photoresist subjected to highly energetic ion irradiation.

Hardness measurements of Ar[sup +]-beam treated polyimide by depth-sensing ultra low load indentation  

SciTech Connect

Polyimide Kapton and spin-cast polyamic acid (PAA) on sapphire have been implanted with 1 MeV Ar ions to a dose of 4.7[times]10[sup 15] cm[sup [minus]2] at ambient temperature. The properties of both pristine and implanted surfaces were characterized by a depth-sensing low-load indentation technique. Experiments were carried out to investigate the effects of substrate, indentation rate, relaxation, and indentation technique. The results showed that (1) hardness was depth-dependent and decreased with increasing indentation depth, (2) measurements of the ion beam hardened surface with the untreated material as a substrate underestimated the hardness while measurements over the sapphire substrate overestimated it, (3) the effects of loading/unloading rates were apparent in the load displacement results, and (4) hardness values measured using the force modulation technique showed very little depth dependence. The hardness value at 100 nm depth is used for comparison purposes since the hardness value at this depth was almost independent of substrate, indentation rate, and indentation method. The hardness of Kapton, which was measured using the techniques described herein, was increased by over 30 times after Ar implantation, from 0.43 to 13 GPa at 100 nm indentation depth. A similar increase in hardness was also observed for polyamic acid. This result suggests that spin-cast PAA film may have potential technological applications for protective coatings where hardness and wear resistance are required.

Reply to Comment on "High-Precision Determination of the Electric and Magnetic Form Factors of the Proton"  

E-Print Network (OSTI)

In arXiv:1108.3058v1 [nucl-ex], Arrington criticizes the Coulomb corrections we applied in the analysis of high precision form factor data (see Phys.Rev.Lett.105:242001, 2010, arXiv:1007.5076v3 [nucl-ex]). We show, by comparing different calculations cited in the Comment, that the criticism of the Comment neglects the large uncertainty of "more modern" TPE corrections. This uncertainty has also been seen in recent polarized measurements. We rerun our analysis using one of these calculations. The results show that the Comment exaggerates the quantitative effect at small Q^2.

Influence of the gap-target configuration on the measured energy loss of C-ions in Ar-gas and -plasma  

Science Journals Connector (OSTI)

Plasma targets for measuring energy loss and charge state distribution of heavy ions in non-ideal Ar-plasmas ( ? -parameters 0.551.5) have been developed and the interaction with several ion species, C, Ar, Xe at 5.9 MeV / u , was studied. Here the results for 5.9 MeV / u C-ions are presented which have been understood just recently by considering the gas dynamics in the target due to the special configuration with the gap interaction zone for the plasma, which can be also simulated by the VarJet code.

Cl37(p,n)Ar37 excitation function up to 24 MeV: Study of (p,n) reactions  

Science Journals Connector (OSTI)

Cross sections for the Cl37(p,n)Ar37 reaction were determined from 2 to 24 MeV by the activation method. NaCl targets of natural isotopic composition were irradiated inside of Al cells having thin Havar windows. Beam intensities were determined with a Faraday cup and the Ar37 disintegration rates were measured with internal gas proportional counters. The cross sections (6% uncertainty) increase from threshold (1.64 MeV) to a broad maximum of 365 mb at 10 MeV and then decrease to 34 mb at 23.5 MeV. These results and five other recently measured (p,n) excitation functions are compared with each other and with various cascade-evaporation calculations. Reasonable agreement was attained between experiment and calculation, and possible sources of remaining discrepancies are discussed. The Ar37 half-life is observed to be 35.020.05 day, in good agreement with previously reported values.NUCLEAR REACTIONS Cl37(p,n), E=2-24 MeV; measured ?(E).

Comment on "Anomalous temperature dependence of the Casimir force for thin metal films" [arXiv:0712.1395

Recently V. A. Yampol'skii, S. Savel'ev, Z. A. Mayselis, S. S. Apostolov, and F. Nori [Phys. Rev. Lett., v.101, 096803 (2008),arXiv:0712.1395] claimed that the Casimir force between a thin metal film described by the Drude model and an ideal metal semispace can decrease with temperature whereas for bulk samples the Casimir force increases with temperature. On this basis the experimental observation of the decreasing temperature dependence of the Casimir force magnitude between a film and a bulk ideal metal was proposed. We demonstrate that, contrary to what is claimed by the authors, the magnitude of the Casimir force decreases with temperature in a wide temperature region for bulk samples described by the Drude model. This decrease is shown to be much larger than that for a thin film and it has already been experimentally excluded.

Effect of radical fluorination on mono- and bi-layer graphene in Ar/F{sub 2} plasma  

SciTech Connect

Fluorinated graphene has the possibility to achieve unique properties and functions in graphene. We propose a highly controlled fluorination method utilizing fluorine radicals in Ar/F{sub 2} plasma. To suppress ion bombardments and improve the reaction with fluorine radicals on graphene, the substrate was placed 'face down' in the plasma chamber. Although monolayer graphene was more reactive than bilayer, fluorination of bilayer reached the level of I{sub D}/I{sub G} {approx} 0.5 in Raman D peak intensity at 532 nm excitation. Annealing fluorinated samples proved reversibility of radical fluorination for both mono- and bi-layer graphenes. X-ray photoelectron spectroscopy showed the existence of carbon-fluorine bonding.

Science Journals Connector (OSTI)

Three new rovibrational bands of ArD2O have been observed in the ?2 bending region of D2O using a quantum cascade laser based cavity ringdown spectrometer. In addition, further observations of the ?(110, ?2=1)??(101) band reported by Li et al. (J. Mol. Spectrosc. 272 (2012) 2731) have been made. All bands were fit by treating the complex using a pseudo-diatomic model which treats the D2O as a free rotor within the complex. Molecular constants have been obtained using this model and are reported with deviations in the fits ranging from 0.0002cm?1 to 0.0005 cm?1. Two of the newly observed bands are tentatively assigned as the ?(202, ?2=1)??(111) and ?(211, ?2=1)??(202) bands, which have not previously been observed in other spectral regions.

Effects of He and Ar ion kinetic energies in protection of organosilicate glass from O{sub 2} plasma damage  

SciTech Connect

In-situ x-ray photoelectron spectroscopy (XPS) and ex-situ Fourier transform infrared studies of He plasma and Ar{sup +} ion bombardment pretreatments of organosilicate glass demonstrate that such pretreatments inhibit subsequent O{sub 2} plasma-induced carbon loss by forming a SiO{sub 2}-like damaged overlayer, and that the degree of protection correlates directly with increased ion kinetic energies, but not with the thickness of the SiO{sub 2} overlayer. This thickness is observed by XPS to be roughly constant and <1 nm regardless of ion energies involved. The data indicate that ion kinetic energies are an important parameter in protective noble gas plasma pretreatments to inhibit O{sub 2} plasma-induced carbon loss.

Collective motion in Ar+Pb collision at beam energies between 400 and 1800 MeV/nucleon  

SciTech Connect

The energy dependence of rapidity distributions and flow effects was studied in central Ar+Pb collisions at 400, 800, and 1800 MeV/nucleon using a streamer chamber. Rapidity distributions for proton and pions are found to have a Gaussian shape whereas those for deuterons exhibit a two-peak structure at the two higher energies. The average in-plane transverse momentum per/nucleon and per/event shows saturation of flow around 800 MeV/nucleon for this asymmetric system. The aspect ratio of the sphericity tensor is closely correlated with the flow angle. This correlation appears to be independent of beam energy. The number of participating nucleons in central collisions varies from 213 at 400 to 135 at 1800 MeV/nucleon indicating that at the lowest energy almost the entire target nucleus participates in the collision.

ArF laser-based quantum well intermixing in InGaAs/InGaAsP heterostructures  

SciTech Connect

Radiation from a 193 nm ArF laser was investigated to modify surface properties of InGaAs/InGaAsP quantum well (QW) heterostructures and introduce defects required to enhance intermixing during the annealing process. A top 200 nm thick sacrificial layer of InP served as a reservoir for laser generated defects. The irradiation with up to 90 pulses at 65-150 mJ/cm{sup 2} allowed to generate an array of 1.2x1 mm{sup 2} sites of QW intermixed material, with bandgap energy blueshifted up to 107 nm. We discuss the mechanism and advantages of this approach for postgrowth wafer level fabrication of multibandgap QW material.

Communication: Determining the structure of the N{sub 2}Ar van der Waals complex with laser-based channel-selected Coulomb explosion  

SciTech Connect

We experimentally reconstructed the structure of the N{sub 2}Ar van der Waals complex with the technique of laser-based channel-selected Coulomb explosion imaging. The internuclear distance between the N{sub 2} center of mass and the Ar atom, i.e., the length of the van der Waals bond, was determined to be 3.88 from the two-body explosion channels. The angle between the van der Waals bond and the N{sub 2} principal axis was determined to be 90 from the three-body explosion channels. The reconstructed structure was contrasted with our high level ab initio calculations. The agreement demonstrated the potential application of laser-based Coulomb explosion in imaging transient molecular structure, particularly for floppy van der Waals complexes, whose structures remain difficult to be determined by conventional spectroscopic methods.

Measurements of linestrengths, N2-, Ar-, He- and self-broadening coefficients of acetylene in the ?4+?5 combination band using a cw quantum cascade laser  

Science Journals Connector (OSTI)

Abstract Linestrengths, N2-, Ar-, He- and self-broadening coefficients of acetylene have been measured at 296K in the P branch of the ?4+?5 combination band for 25 rotational transitions. The effect of gas temperature is studied over 296683K for five transitions to allow the determination of the temperature dependent exponent n for N2- and Ar-broadening coefficients. These measurements were performed using a continuous-wave quantum cascade laser (cw-QCL) operating over 12531310cm?1. Spectroscopic parameters were obtained by fitting absorption spectra using Voigt, Galatry and Rautian profiles. Linestrength and broadening results are compared with previous studies available in literature for the ?4+?5 combination band and other vibrational bands of acetylene.

COMMIX-1AR/P: A three-dimensional transient single-phase computer program for thermal hydraulic analysis of single and multicomponent systems  

SciTech Connect

The COMMIX-1AR/P computer program is designed for analyzing the steady-state and transient aspects of single-phase fluid flow and heat transfer in three spatial dimensions. This version is an extension of the modeling in COMMIX-1A to include multiple fluids in physically separate regions of the computational domain, modeling descriptions for pumps, radiation heat transfer between surfaces of the solids which are embedded in or surround the fluid, a k-[var epsilon] model for fluid turbulence, and improved numerical techniques. The porous-medium formulation in COMMIX allows the program to be applied to a wide range of problems involving both simple and complex geometrical arrangements. The input preparation and execution procedures are presented for the COMMIX-1AR/P program and several postprocessor programs which produce graphical displays of the calculated results.

Three-dimensional Magnetic Restructuring in Two Homologous Solar Flares in the Seismically Active NOAA AR 11283  

E-Print Network (OSTI)

We carry out a comprehensive investigation comparing the three-dimensional magnetic field restructuring, flare energy release, and the helioseismic response, of two homologous flares, the 2011 September 6 X2.1 (FL1) and September 7 X1.8 (FL2) flares in NOAA AR 11283. In our analysis, (1) a twisted flux rope (FR) collapses onto the surface at a speed of 1.5 km/s after a partial eruption in FL1. The FR then gradually grows to reach a higher altitude and collapses again at 3 km/s after a fuller eruption in FL2. Also, FL2 shows a larger decrease of the flux-weighted centroid separation of opposite magnetic polarities and a greater change of the horizontal field on the surface. These imply a more violent coronal implosion with corresponding more intense surface signatures in FL2. (2) The FR is inclined northward, and together with the ambient fields, it undergoes a southward turning after both events. This agrees with the asymmetric decay of the penumbra observed in the peripheral regions. (3) The amounts of free ...

Comment on 'A Scaling law beyond Zipf's law and its relation to Heaps' law' [arXiv:1303.0705  

E-Print Network (OSTI)

It is shown that the scaling law for the text-length dependence of word-frequency distributions proposed by Font-Clos et al in 2013 [New J. Phys. 15 093033, arXiv:1303.0705] is fundamentally impossible and leads to incorrect conclusions. Instead the text-length-dependence can be connected to the general properties of a random book with consistent agreement. It is pointed out that this finding has strong implications, when deciding between two conceptually different views on word-frequency distributions, i.e. the `Zipf's-view' and the `Randomness-view', as is discussed. It is also noticed that the text-length transformation of a random book does have an exact scaling property precisely for the power-law index $\\gamma=1$, as opposed to the Zipf's exponent $\\gamma=2$ and the implication of this exact scaling property is discussed. However a real text has $\\gamma>1$ and as a consequence $\\gamma$ increases when shortening a real text, contrary to the claim by Font-Clos et al in 2013 New J. Phys. 15 093033. The con...

The PlioQuaternary volcanic evolution of Gran Canaria based on new KAr ages and magnetostratigraphy  

Science Journals Connector (OSTI)

The combined use of radiometric dating (51 new unspiked KAr ages), magnetostratigraphy and field geology establishes a new time framework for the last two stages of the volcanic evolution of Gran Canaria. Most of the dated samples have ages coherent with their stratigraphic positions and magnetic polarities. Our new set of data extends the end of the Roque Nublo (RN) group, one of the main posterosive stages of Gran Canaria which started about 4.9 Ma ago, to ages as young as 2.87 Ma. This is about 0.7 Ma younger than previously thought. Moreover, the dating of samples collected in well-defined stratigraphic sequences supports the contemporaneity of the early stages of the post-Roque Nublo group and the vanishing activity of the Roque Nublo stratovolcano between 3.7 and 2.9 Ma. The multiple lateral collapses of the Roque Nublo stratovolcano occurred during this period between 3.5 and 3.1 Ma which corresponds to a main period of volcanic quiescence. After 2.9 Ma, the effusive activity propagated along a well-defined NWSE rift until about 1.5 Ma, shifting progressively from a rifting propagation to platform-forming lavas. Thereafter, the activity is very disperse and belongs to the Brunhes period, with most of it before 500 ka.

Selective etching of high-k HfO{sub 2} films over Si in hydrogen-added fluorocarbon (CF{sub 4}/Ar/H{sub 2} and C{sub 4}F{sub 8}/Ar/H{sub 2}) plasmas  

SciTech Connect

Inductively coupled hydrogen-added fluorocarbon (CF{sub 4}/Ar/H{sub 2} and C{sub 4}F{sub 8}/Ar/H{sub 2}) plasmas were used to etch HfO{sub 2}, which is a promising high-dielectric-constant material for the gate of complementary metal-oxide-semiconductor devices. The etch rates of HfO{sub 2} and Si were drastically changed depending on the additive-H{sub 2} flow rate in C{sub 4}F{sub 8}/Ar/H{sub 2} plasmas. The highly selective etching of HfO{sub 2} over Si was done in the condition with an additive-H{sub 2} flow rate, where the Si surface was covered with the fluorocarbon polymer. The results of x-ray photoelectron spectroscopy indicated that the carbon content of the selectively etched HfO{sub 2} surface was extremely low compared with the preetched surface contaminated by adventitious hydrocarbon in atmosphere. In the gas phase of the C{sub 4}F{sub 8}/Ar/H{sub 2} plasmas, Hf hydrocarbide molecules such as metal-organic compounds and Hf hydrofluoride were detected by a quadrupole mass analyzer. These findings indicate that the fluorine species, carbon, and hydrogen can work to etch HfO{sub 2} and that the carbon species also plays an important role in selective etching of HfO{sub 2} over Si.

Absolute CF{sub 2} density and gas temperature measurements by absorption spectroscopy in dual-frequency capacitively coupled CF{sub 4}/Ar plasmas  

SciTech Connect

Broadband ultraviolet absorption spectroscopy has been used to determine the CF{sub 2} radical density in dual-frequency capacitively coupled CF{sub 4}/Ar plasmas, using the CF{sub 2} A{sup ~1}B{sub 1}?X{sup ~1}A{sub 1} system of absorption spectrum. The rotational temperature of ground state CF{sub 2} and excited state CF was also estimated by using A{sup ~1}B{sub 1}?X{sup ~1}A{sub 1} system and B{sup 2}??X{sup 2}? system, respectively. The translational gas temperature was deduced from the Doppler width of the Ar{sup *}({sup 3}P{sub 2}) and Ar{sup *}({sup 3}P{sub 0}) metastable atoms absorption line by using the tunable diode laser absorption spectroscopy. The rotational temperatures of the excited state CF are about 100?K higher than those of ground state CF{sub 2}, and about 200?K higher than the translational gas temperatures. The dependences of the radical CF{sub 2} density, electron density, electron temperature, rotational temperature, and gas temperature on the high frequency power and pressure have been analyzed. Furthermore, the production and loss mechanisms of CF{sub 2} radical and the gas heating mechanisms have also been discussed.

Etching properties of Na0.5K0.5NbO3 thin films by using inductively coupled CF4/Ar plasma  

Science Journals Connector (OSTI)

Abstract The etch process of the Na0.5K0.5NbO3 (NKN) thin film was performed in CF4/Ar plasma. We investigated the etch rate of the NKN thin films and the selectivity of NKN to SiO2 in an inductively coupled plasma. The maximum etch rate of the NKN thin films was 127.3nm/min in CF4/Ar (=4:16sccm) plasma and the selectivity of NKN to SiO2 was 0.31. We analyzed the XPS narrow scan spectra for the reaction on the surface of the NKN thin films. From the XPS data analysis, we were assumed that the byproducts were generated on the surface of the NKN thin films during the etching process, but the physical sputtering process effectively removed the byproducts. We analyzed the morphologies of the surface of the NKN thin films from AFM measurement. The Ar concentration affects the surface morphology greatly.

Atom penetration from a thin film into the substrate during sputtering by polyenergetic Ar{sup +} ion beam with mean energy of 9.4 keV  

SciTech Connect

Penetration of alien atoms (Be, Ni) into Be, Al, Zr, Si and diamond was investigated under Ar{sup +} ion bombardment of samples having thermally evaporated films of 30--50 nm. Sputtering was carried out using a wide energy spectrum beam of Ar{sup +} ions of 9.4 keV to dose D = 1 {times} 10{sup 16}--10{sup 19} ion/cm{sup 2}. Implanted atom distribution in the targets was measured by Rutherford backscattering spectrometry (RBS) of H{sup +} and He{sup +} ions with energy of 1.6 MeV as well as secondary ion mass-spectrometry (SIMS). During the bombardment, the penetration depth of Ar atoms increases with dose linearly. This depth is more than 3--20 times deeper than the projected range of bombarding ions and recoil atoms. This is a deep action effect. The analysis shows that the experimental data for foreign atoms penetration depth are similar to the data calculated for atom migration through the interstitial site in a field of internal (lateral) compressive stresses created in the near-surface layer of the substrate as a result of implantation. Under these experimental conditions atom ratio r{sub i}/r{sub m} (r{sub i} -- radius of dopant, r{sub m} -- radius target of substrate) can play a principal determining role.

Kinetically tailored properties of electron-beam excited XeF(C. -->. A) and XeF(B. -->. X) laser media using an Ar-Kr buffer mixture  

SciTech Connect

Use of a two-component buffer gas comprised of Ar and Kr results in electron-beam excited XeF(C..-->..A) laser pulse energy and intrinsic efficiency values comparable to those of UV rare gas-halide lasers. Herein the authors report measurements of transient absorption confirming that the primary effect of a buffer comprised of Ar and Kr is a significantly lower level of ionized and excited species that absorb in the blue-green spectral region. Spectral analysis of a variety of mixtures show that the Ar-Kr buffer also benefits XeF(C..-->..A) laser performance due to an increase in gain in the 400-450 nm region caused by the presence of the Kr/sub 2/F excimer. In addition, a large increase in absorption at --351 nm, also due to Kr/sub 2/F, suppresses oscillation on the competitive XeF(B..-->..X) transition and, for certain conditions, makes efficient simultaneous oscillation of the XeF(B..-->..X) and XeF(C..-->..A) laser transitions possible.

The PIKfyveArPIKfyveSac3 triad in human breast cancer: Functional link between elevated Sac3 phosphatase and enhanced proliferation of triple negative cell lines  

SciTech Connect

Highlights: We assess PAS complex proteins and phosphoinositide levels in breast cancer cells. Sac3 and ArPIKfyve are markedly elevated in triple-negative breast cancer cells. Sac3 silencing inhibits proliferation in triple-negative breast cancer cell lines. Phosphoinositide profiles are altered in breast cancer cells. This is the first evidence linking high Sac3 with breast cancer cell proliferation. -- Abstract: The phosphoinositide 5-kinase PIKfyve and 5-phosphatase Sac3 are scaffolded by ArPIKfyve in the PIKfyveArPIKfyveSac3 (PAS) regulatory complex to trigger a unique loop of PtdIns3PPtdIns(3,5)P{sub 2} synthesis and turnover. Whereas the metabolizing enzymes of the other 3-phosphoinositides have already been implicated in breast cancer, the role of the PAS proteins and the PtdIns3PPtdIns(3,5)P{sub 2} conversion is unknown. To begin elucidating their roles, in this study we monitored the endogenous levels of the PAS complex proteins in cell lines derived from hormone-receptor positive (MCF7 and T47D) or triple-negative breast cancers (TNBC) (BT20, BT549 and MDA-MB-231) as well as in MCF10A cells derived from non-tumorigenic mastectomy. We report profound upregulation of Sac3 and ArPIKfyve in the triple negative vs. hormone-sensitive breast cancer or non-tumorigenic cells, with BT cell lines showing the highest levels. siRNA-mediated knockdown of Sac3, but not that of PIKfyve, significantly inhibited proliferation of BT20 and BT549 cells. In these cells, knockdown of ArPIKfyve had only a minor effect, consistent with a primary role for Sac3 in TNBC cell proliferation. Intriguingly, steady-state levels of PtdIns(3,5)P{sub 2} in BT20 and T47D cells were similar despite the 6-fold difference in Sac3 levels between these cell lines. However, steady-state levels of PtdIns3P and PtdIns5P, both regulated by the PAS complex, were significantly reduced in BT20 vs. T47D or MCF10A cell lines, consistent with elevated Sac3 affecting directly or indirectly the homeostasis of these lipids in TNBC. Together, our results uncover an unexpected role for Sac3 phosphatase in TNBC cell proliferation. Database analyses, discussed herein, reinforce the involvement of Sac3 in breast cancer pathogenesis.

Evaluation of cloud fraction and its radiative effect simulated by IPCC AR4 global models against ARM surface observations  

SciTech Connect

Cloud Fraction (CF) is the dominant modulator of radiative fluxes. In this study, we evaluate CF simulations in the IPCC AR4 GCMs against ARM ground measurements, with a focus on the vertical structure, total amount of cloud and its effect on cloud shortwave transmissivity, for both inter-model deviation and model-measurement discrepancy. Our intercomparisons of three CF or sky-cover related dataset reveal that the relative differences are usually less than 10% (5%) for multi-year monthly (annual) mean values, while daily differences are quite significant. The results also show that the model-observation and the inter-model deviations have a similar magnitude for the total CF (TCF) and the normalized cloud effect, and they are twice as large as the surface downward solar radiation and cloud transmissivity. This implies that the other cloud properties, such as cloud optical depth and height, have a similar magnitude of disparity to TCF among the GCMs, and suggests that a better agreement among the GCMs in solar radiative fluxes could be the result of compensating errors in either cloud vertical structure, cloud optical depth or cloud fraction. Similar deviation pattern between inter-model and model-measurement suggests that the climate models tend to generate larger bias against observations for those variables with larger inter-model deviation. The simulated TCF from IPCC AR4 GCMs are very scattered through all seasons over three ARM sites: Southern Great Plains (SGP), Manus, Papua New Guinea and North Slope of Alaska (NSA). The GCMs perform better at SGP than at Manus and NSA in simulating the seasonal variation and probability distribution of TCF; however, the TCF in these models is remarkably underpredicted and cloud transmissivity is less susceptible to the change of TCF than the observed at SGP. Much larger inter-model deviation and model bias are found over NSA than the other sites in estimating the TCF, cloud transmissivity and cloud-radiation interaction, suggesting that the Arctic region continues to challenge cloud simulations in climate models. Most of the GCMs tend to underpredict CF and fail to capture the seasonal variation of CF at middle and low levels in the tropics. The high altitude CF is much larger in the GCMs than the observation and the inter-model variability of CF also reaches maximum at high levels in the tropics. Most of the GCMs tend to underpredict CF by 50-150% relative to the measurement average at low and middle levels over SGP. While the GCMs generally capture the maximum CF in the boundary layer and vertical variability, the inter-model deviation is largest near surface over the Arctic. The internal variability of CF simulated in ensemble runs with the same model is very minimal.

As-Received, Ozone Cleaned and Ar+ Sputtered Surfaces of Hafnium Oxide Grown by Atomic Layer Deposition and Studied by XPS  

SciTech Connect

In this study, X-ray photoelectron spectroscopy (XPS) characterization was performed on 47 nm thick hafnium oxide (HfO{sub 2}) films grown by atomic layer deposition using TEMA-Hf/H{sub 2}O at 250 C substrate temperature. HfO{sub 2} is currently being studied as a possible replacement for Silicon Oxide (SiO{sub 2}) as a gate dielectric in electronics transistors. XPS spectra were collected on a Physical Electronics Quantum 2000 Scanning ESCA Microprobe using a monochromatic Al K{sub a} X-ray (1486.7 eV) excitation source. The sample was analyzed under the following conditions: as received, after UV irradiation for five minutes, and after sputter cleaning with 2 kV Ar{sup +} ions for 180 seconds. Survey scans showed carbon, oxygen, and hafnium as the major species in the film, while the only minor species of argon and carbide was detected after sputtering. Adventitious carbon initially composed approximately 18.6 AT% of the surface, but after UV cleaning it was reduced to 2.4 AT%. This demonstrated that that the majority of carbon was due to adventitious carbon. However, after 2 kV Ar{sup +} sputtering there was still only trace amounts of carbon at {approx}1 AT%, Some of this trace carbon is now in the form of a carbide due to the interaction with Ar{sup +} used for sputter cleaning. Furthermore, the stoiciometric ratio of oxygen and hafnium is consistent with a high quality HfO{sub 2} film.

XPS on corrosion products of ZnCr coated steel: on the reliability of Ar+ ion depth profiling for multi component material analysis  

E-Print Network (OSTI)

X-ray photoelectron spectroscopy combined with Ar+ ion etching is a powerful concept to identify different chemical states of compounds in depth profiles, important for obtaining information underneath surfaces or at layer interfaces. The possibility of occurring sputter damage is known but insufficiently investigated for corrosion products of Zn-based steel coatings like ZnCr. Hence, in this work reference materials are studied according to stability against ion sputtering. Indeed some investigated compounds reveal a very unstable chemical nature. On the basis of these findings the reliability of depth profiles of real samples can be rated to avoid misinterpretations of observed chemical species.

Rotational spectrum of HD perturbed by He or Ar gases: The effects of rotationally inelastic collisions on the interference between allowed and collisionally induced components  

Science Journals Connector (OSTI)

The spectral line shapes for the HD rotational spectra perturbed by He and Ar gases, which show interference between allowed and collisionally induced dipole transitions, are calculated including the effects of inelastic rotational collisions. The general parametrization of the line shape, including inelastic collisions, requires six independent real parameters as opposed to four in the theory of Herman, Tipping, and Poll [Phys. Rev. A 20, 2006 (1979)]. Semiclassical calculations based on classical trajectories indicate the importance of the inelastic effects and show qualitative agreement with the experimental parameters. However, it is clear that a full explanation of experimental data will eventually require a full quantum treatment.

Further evidence for a stiff nuclear equation of state from a transverse-momentum analysis of Ar(1800 MeV/nucleon) + KCl  

SciTech Connect

The novel momentum analysis technique introduced by Danielewicz and Odyniec can be used to detect and exhibit collective flow in the light system Ar(1800 MeV/nucleon) + KCl where the usual kinetic energy flow analysis fails. The microscopic Vlasov-Uehling-Uhlenbeck theory which includes the nuclear mean field, two-body collisions, and Pauli blocking is used to study this phenomenon. The resulting transverse momentum transfers turn out to be quite sensitive to the nuclear equation of state. From a comparison with experimental data, evidence is presented for a rather stiff nuclear equation of state. The cascade model is unable to describe the data.

Effects of N{sub 2}, O{sub 2}, and Ar plasma treatments on the removal of crystallized HfO{sub 2} film  

SciTech Connect

The effects of plasma treatment using Ar, N{sub 2}, and O{sub 2} on the removal of crystallized HfO{sub 2} films in a dilute HF solution were studied. The resulting damage in source and drain regions, and recess in isolation regions were also investigated. It was found that plasma nitridation with an ion energy of several hundred electron volts can lower the wet etch resistance of crystallized HfO{sub 2} films up to 70 A thick through the generation of Hf-N bonds. However, thermal nitridation did not introduce sufficient nitrogen into bulk crystallized HfO{sub 2} films to lower wet etch resistance. Plasma nitridation without bias power introduced nitrogen to the crystallized HfO{sub 2} in the region only within 10 A of the surface. The enhancement of the etch rate of crystallized HfO{sub 2} in dilute HF and the amount of recess in the active and isolation regions using N{sub 2}, O{sub 2}, and Ar plasma treatment have been evaluated. Results show that N{sub 2} plasma treatment is the most effective in enhancing the removal rate of crystallized HfO{sub 2} in dilute HF and minimizing recess on substrate among the plasmas studied.

Surface loss probability of atomic hydrogen for different electrode cover materials investigated in H{sub 2}-Ar low-pressure plasmas  

SciTech Connect

In an inductively coupled H{sub 2}-Ar plasma at a total pressure of 1.5?Pa, the influence of the electrode cover material on selected line intensities of H, H{sub 2}, and Ar are determined by optical emission spectroscopy and actinometry for the electrode cover materials stainless steel, copper, tungsten, Macor{sup }, and aluminum. Hydrogen dissociation degrees for the considered conditions are determined experimentally from the measured emission intensity ratios. The surface loss probability ?{sub H} of atomic hydrogen is correlated with the measured line intensities, and ?{sub H} values are determined for the considered materials. Without the knowledge of the atomic hydrogen temperature, ?{sub H} cannot be determined exactly. However, ratios of ?{sub H} values for different surface materials are in first order approximation independent of the atomic hydrogen temperature. Our results show that ?{sub H} of copper is equal to the value of stainless steel, ?{sub H} of Macor{sup } and tungsten is about 2 times smaller and ?{sub H} of aluminum about 5 times smaller compared with stainless steel. The latter ratio is in reasonable agreement with literature. The influence of the atomic hydrogen temperature T{sub H} on the absolute value is thoroughly discussed. For our assumption of T{sub H}?=?600?K, we determine a ?{sub H} for stainless steel of 0.39??0.13.

Origin of the ore-forming fluids of the Tongchang porphyry CuMo deposit in the JinshajiangRed River alkaline igneous belt, SW China: Constraints from He, Ar and S isotopes  

Science Journals Connector (OSTI)

The JinshajiangRed River alkaline igneous belt with abundant CuMoAu mineralization, in the eastern IndianAsian collision zone, is an important Cenozoic magmatic belt formed under an intra-continental strike-slip system in southwestern (SW) China. The Tongchang deposit is a representative porphyry CuMo deposit in southern segment of the JinshajiangRed River alkaline igneous belt, with 8621t Cu @ 1.24wt.% and 17,060t Mo @ 0.218wt.%. In this study, He, Ar and S isotopic compositions of the Tongchang deposit were determined. He and Ar isotopic compositions suggest that the ore-forming fluids, with 3He/4He ratios varying from 0.17 to 1.50Ra and 40Ar/36Ar ratios from 299.1 to 347.3 for the deposit, are a mixture between a crust-derived fluid (MASW) with near atmospheric Ar and crustal He, and a mantle-derived fluid. However, the ?34S values of the hydrothermal pyrite samples ranging from 1.0 to 1.5 with an average of 1.2, indicate that the sulfur in the ore-forming fluids of the Tongchang deposit was primarily derived from the magma or indirectly mantle-derived without assimilation of crustal sulfur. In combination with previously published He and Ar isotopic data of the Yulong and Machangqing deposits in northern and central segments of the JinshajiangRed River alkaline igneous belt, respectively, the ore-forming fluids of the Yulong and Machangqing deposits are obviously richer in 3He and 40Ar, and poorer in 36Ar in comparison with the Tongchang deposit, implying that more mantle-derived fluids were involved in the ore-forming fluids of the Yulong and Machangqing deposits than those for the Tongchang deposit. This might be one of the most important factors producing larger scales of mineralization in the Yulong and Machangqing deposits than the Tongchang deposit.

InGaZnO thin film transistor with HfO{sub 2} gate insulator prepared using various O{sub 2}/(Ar + O{sub 2}) gas ratios  

SciTech Connect

We have investigated the effect of the deposition of an HfO{sub 2} thin film as a gate insulator with different O{sub 2}/(Ar + O{sub 2}) gas ratios using RF magnetron sputtering. The HfO{sub 2} thin film affected the device performance of amorphous indiumgalliumzinc oxide transistors. The performance of the fabricated transistors improved monotonously with increasing O{sub 2}/(Ar + O{sub 2}) gas ratio: at a ratio of 0.35, the field effect mobility of the amorphous InGaZnO thin film transistors was improved to 7.54 cm{sup 2}/(V s). Compared to those prepared with an O{sub 2}/(Ar + O{sub 2}) gas ratio of 0.05, the field effect mobility of the amorphous InGaZnO thin film transistors was increased to 1.64 cm{sup 2}/(V s) at a ratio of 0.35. This enhancement in the field effect mobility was attributed to the reduction of the root mean square roughness of the gate insulator layer, which might result from the trap states and surface scattering of the gate insulator layer at the lower O{sub 2}/(Ar + O{sub 2}) gas ratio.

Formation of anions and cations via a binary-encounter process in OH$^+$ + Ar collisions: the role of dissociative excitation and statistical aspects  

E-Print Network (OSTI)

Molecular fragmentation leading to the formation of negatively and positively charged hydrogen ions in 7-keV OH$^+$ + Ar collisions is investigated experimentally. The most striking finding is that negative and positive hydrogen ions are emitted with very similar angular dependences. Also, the kinetic energy distribution of the H$^+$ fragment shows strong similarities with that of the ejected H$^-$ ion. The kinematics of the emitted H core is found to be essentially driven by its scattering on the atomic target. However, in addition to this binary-encounter process, dissociative electronic excitation of the molecular projectile has to be invoked to explain the observed fragmentation patterns. Though the electron capture process is complex, it is shown that the relative population of the different final charge states of the outgoing fragments can be described by simple statistical laws.

Criteria of radio-frequency ring-shaped hollow cathode discharge using H{sub 2} and Ar gases for plasma processing  

SciTech Connect

In order to achieve high-density capacitively coupled plasma, a radio-frequency (RF) ring-shaped hollow cathode discharge has been developed as a candidate for processing plasma sources. The plasma density in the hollow cathode discharge reaches a high magnitude of 10{sup 10}-10{sup 11} cm{sup -3}. The RF ring-shaped hollow cathode discharge depends on the pressure and mass of the working gas. Criteria required for producing a RF ring-shaped hollow cathode discharge have been investigated for various gas pressures using H{sub 2} and Ar gases for high-density plasma production. The results reveal that the criteria for the occurrence of the hollow cathode effect are that the trench width should be approximately equal to the sum of the electron-neutral mean free paths and twice the sheath thickness of the RF powered electrode.

Formation of silver nanoparticles inside a soda-lime glass matrix in the presence of a high intensity Ar{sup +} laser beam  

SciTech Connect

Formation and motion of the silver nanoparticles inside an ion-exchanged soda-lime glass in the presence of a focused high intensity continuous wave Ar{sup +} laser beam (intensity: 9.2 x 10{sup 4} W/cm{sup 2}) have been studied in here. One-dimensional diffusion equation has been used to model the diffusion of the silver ions into the glass matrix, and a two-dimensional reverse diffusion model has been introduced to explain the motion of the silver clusters and their migration toward the glass surface in the presence of the laser beam. The results of the mentioned models were in agreement with our measurements on thickness of the ion-exchange layer by means of optical microscopy and recorded morphology of the glass surface around the laser beam axis by using a Mirau interferometer. SEM micrographs were used to extract the size distribution of the migrated silver particles over the glass surface.

Multiplicity dependence of azimuthal distributions for [sup 36]Ar+[sup 197]Au collisions at [ital E]/[ital A]=35 MeV  

SciTech Connect

Collisions between [sup 36]Ar projectile and [sup 197]Au target nuclei at [ital E]/[ital A]=35 MeV have been studied with the Michigan State University Miniball, a 4[pi] phoswich array with a low detection threshold. Azimuthal distributions of charged particles with respect to the reaction plane are determined via the transverse-momentum-tensor method. Dependence on the kinetic energy of the emitted particles, the collision geometry, and the associated charged particle multiplicity is investigated. Corrections for the intrinsic resolution of the experimental reaction plane determination are applied. Scaling implied by the coalescence model is explored and the data are compared to the results of microscopic calculations within the Boltzmann-Uehling-Uhlenbeck theory.

Inexpensive discrete atomistic model technique for studying excitations on infinite disordered media: the case of orientational glass ArN$_2$  

E-Print Network (OSTI)

Excitations of disordered systems such as glasses are of fundamental and practical interest but computationally very expensive to solve. Here we introduce a technique for modeling these excitations in an infinite disordered medium with a reasonable computational cost. The technique relies on a discrete atomic model to simulate the low-energy behavior of an atomic lattice with molecular impurities. The interaction between different atoms is approximated using a spring like interaction based on the Lennard Jones potential but can be easily adapted to other potentials. The technique allows to solve a statistically representative number of samples with a minimum of computational expense, and uses a Monte-Carlo approach to achieve a state corresponding to any given temperature. This technique has already been applied successfully to a problem with interest in condensed matter physics: the solid solution of N$_2$ in Ar.

Characteristics of high-purity Cu thin films deposited on polyimide by radio-frequency Ar/H2 atmospheric-pressure plasma jet  

Science Journals Connector (OSTI)

With a view to fabricating future flexible electronic devices an atmospheric-pressure plasma jet driven by 13.56?MHz radio-frequency power is developed for depositing Cu thin films on polyimide where a Cu wire inserted inside the quartz tube was used as the evaporation source. A polyimide substrate is placed on a water-cooled copper heat sink to prevent it from being thermally damaged. With the aim of preventing oxidation of the deposited Cu film we investigated the effect of adding H2 to Ar plasma on film characteristics. Theoretical fitting of the OH emission line in OES spectrum revealed that adding H2 gas significantly increased the rotational temperature roughly from 800 to 1500?K. The LMM Auger spectroscopy analysis revealed that higher-purity Cu films were synthesized on polyimide by adding hydrogen gas. A possible explanation for the enhancement in the Cu film deposition rate and improvement of purity of Cu films by H2 gas addition is that atomic hydrogen produced by the plasma plays important roles in heating the gas to promote the evaporation of Cu atoms from the Cu wire and removing oxygen from copper oxide components via reduction reaction.

Self-consistent particle modeling of radio frequency discharge in Ar/O{sub 2} mixtures: Effects of crossed electric and magnetic fields and partial pressure  

SciTech Connect

A particle-in-cell/Monte Carlo model is developed to study and analyze the electrical characteristics of the nonequilibrium plasma created by radio frequency (RF) discharge in Ar/O{sub 2} mixtures in the presence of crossed electric and magnetic fields. The method of collision treatment is based on an optimized estimation of the free time flight. The needed basic data--more specifically, the ion-neutral cross sections--are determined first. The simulation conditions are 50 mTorr for the total gas pressure and 200 V for the peak of the RF voltage at a frequency of 13.56 MHz. The magnetic field is varied from 0 to 50 G. The effect of the partial pressure ratio of O{sub 2} in the mixture and the effect of the magnitude of the magnetic field are discussed. In particular, the results show an increase of the plasma density that is ten times higher in the presence of a magnetic field.

Role of the induced dipole moment in the collisional interference in the pure rotational spectrum of HD-He and HD-Ar  

Science Journals Connector (OSTI)

The parameters describing the interference between allowed and collision-induced transitions in the far-infrared spectrum of HD-He and HD-Ar are computed following the formalism of Gao et al. [Phys. Rev. A 44, 7379 (1991)] and the calculational procedure of Gao et al. [Phys. Rev. A 46, 5781 (1992)]. The contribution from each component of the induced-dipole moment is identified. The interference between the induced-dipole component having the same symmetry as the allowed moment and the allowed moment itself has the largest single contribution to the intensity interference effect. The mixing of rotational levels by an anisotropic intermolecular interaction introduces other components into the interference mechanism. The overall effect is usually to decrease the magnitude of the interference and to permit line broadening and asymmetry to occur. This interaction is most effective in causing the anisotropic overlap-induced pair dipole moment B2(21) to play a role in the interference mechanism. The effect of the isotropic overlap-induced dipole moment is usually negligible.

Feedback control of HfO{sub 2} etch processing in inductively coupled Cl{sub 2}/N{sub 2}/Ar plasmas  

SciTech Connect

The etch rate of HfO{sub 2} etch processing has been feedback controlled in inductively coupled Cl{sub 2}/N{sub 2}/Ar plasmas. The ion current and the root mean square rf voltage on the wafer stage, which are measured using a commercial impedance meter connected to the wafer stage, are chosen as controlled variables because the positive-ion flux and ion energy incident upon the wafer surface are the key factors that determine the etch rate. Two 13.56 MHz rf generators are used to adjust the inductively coupled plasma power and bias power which control ion density and ion energy, respectively. The adopted HfO{sub 2} etch processing used rather low rf voltage. The ion-current value obtained by the power/voltage method is underestimated, so the neural-network model was developed to assist estimating the correct ion-current value. The experimental results show that the etch-rate variation of the closed-loop control is smaller than that of the open-loop control. However, the first wafer effect cannot be eliminated using closed-loop control and thus to achieve a constant etch rate, the chamber-conditioning procedure is required in this etch processing.

Epitaxial growth of Si1?xGex alloys and Ge on Si(100) by electron-cyclotron-resonance Ar plasma chemical vapor deposition without substrate heating  

Science Journals Connector (OSTI)

Abstract By using electron-cyclotron-resonance (ECR) Ar-plasma chemical vapor deposition (CVD) without substrate heating, the epitaxial growth process of Si1?xGex alloy and Ge films deposited directly on dilute-HF-treated Si(100) was investigated. From the reflection high energy electron diffraction patterns of the deposited Si1?xGex alloy (x=0.50, 0.75) and Ge films on Si(100), it is confirmed that epitaxial growth can be realized without substrate heating, and that crystallinity degradation at larger film thickness is observed. The X-ray diffraction peak of the epitaxial films reveals the existence of large compressive strain, which is induced by lattice matching with the Si(100) substrate at smaller film thicknesses, as well as strain relaxation behavior at larger film thicknesses. The Ge fraction of Si1?xGex thin film is in good agreement with the normalized GeH4 partial pressure. The Si1?xGex deposition rate increases with an increase of GeH4 partial pressure. The GeH4 partial pressure dependence of partial deposition rates [(Si or Ge fraction)נ(Si1?xGex thickness)/(deposition time)] shows that the Si partial deposition rate is slightly enhanced by the existence of Ge. From these results, it is proposed that the ECR-plasma CVD process can be utilized for Ge fraction control in highly-strained heterostructure formation of group IV semiconductors.

Studies of the Low-Lying States of K41 via the Reactions Ar41(?-)K41 and K41(p,p??)K41  

Science Journals Connector (OSTI)

The 110-min ?- decay of the 72- ground state of Ar41 to excited states of K41 was investigated by observation of the deexcitation K41 ? rays with a Ge(Li) detector. In addition, both (p?,?) coincidence measurements and a magnetic spectrometer study were made of the reaction K41(p,p?)K41 at proton energies between 5.3 and 5.8 MeV. The (p?,?) work gave ?-ray decay-mode information used in the analysis of the ?--decay studies. The magnetic spectrometer studies confirmed a new level of K41 at 1594 3 keV observed in the (p?,?) work. The ?- decay to the K41 sixth excited state (Ex=1677.00.3 keV) observed previously by Pratt was confirmed. The branch was found to be (5.2 0.5) 10-2%, corresponding to an allowed logf0t value of 7.68 0.04. Rather severe upper limits were placed on any other branches to excited states except the major one to the 72- state at 1294 keV.

Reactions of He/sup +/, Ne/sup +/, and Ar/sup +/ with CH/sub 4/, C/sub 2/H/sub 6/, SiH/sub 4/, and Si/sub 2/H/sub 6/  

SciTech Connect

The rate coefficients and product-ion distributions for the reactions of He/sup +/ and Ar/sup +/ with silane and disilane have been measured in a drift tube, typically for collision energies of 0.01--1 eV. The total charge-exchange rate coefficients are found to be roughly independent of E/N, or collision energy, and are about equal to the Langevin values for the reactions of He/sup +/ with SiH/sub 4/ and C/sub 2/H/sub 6/ and Ar/sup +/ with CH/sub 4/ and C/sub 2/H/sub 6/. The He/sup +/ rate coefficients on CH/sub 4/ and Si/sub 2/H/sub 6/, and the Ne/sup +/ rate coefficients on SiH/sub 4/ and Si/sub 2/H/sub 6/ are 50% to 80% of the Langevin values, while the Ar/sup +/ rate coefficients on SiH/sub 4/ and Si/sub 2/H/sub 6/ are much smaller. Product ions tend to be hydrogen poor with very infrequent breaking of the C--C or Si--Si bonds. Furthermore, hydrogen stripping is more severe for the silanes than the alkanes. These product-ion distributions bear no resemblance to the product-ion distributions of either photoionization or electron collisional ionization.

Neutron Diffraction Studies of a Class A beta-Lactamase Toho-1 E166A/R274N/R276N Triple Mutant  

SciTech Connect

beta-Lactam antibiotics have been used effectively over several decades against many types of bacterial infectious diseases. However, the most common cause of resistance to the beta-lactam antibiotics is the production of beta-lactamase enzymes that inactivate beta-lactams by rapidly hydrolyzing the amide group of the beta-lactam ring. Specifically, the class A extended-spectrum beta-lactamases (ESBLs) and inhibitor-resistant enzymes arose that were capable of hydrolyzing penicillins and the expanded-spectrum cephalosporins and monobactams in resistant bacteria, which lead to treatment problems in many clinical settings. A more complete understanding of the mechanism of catalysis of these ESBL enzymes will impact current antibiotic drug discovery efforts. Here, we describe the neutron structure of the class A, CTX-M-type ESBL Toho-1 E166A/R274N/R276N triple mutant in its apo form, which is the first reported neutron structure of a beta-lactamase enzyme. This neutron structure clearly reveals the active-site protonation states and hydrogen-bonding network of the apo Toho-1 ESBL prior to substrate binding and subsequent acylation. The protonation states of the active-site residues Ser70, Lys73, Ser130, and Lys234 in this neutron structure are consistent with the prediction of a proton transfer pathway from Lys73 to Ser130 that is likely dependent on the conformation of Lys73, which has been hypothesized to be coupled to the protonation state of Glu166 during the acylation reaction. Thus, this neutron structure is in agreement with a proposed mechanism for acylation that identifies Glu166 as the general base for catalysis.

Role of the blocking capacitor in control of ion energy distributions in pulsed capacitively coupled plasmas sustained in Ar/CF{sub 4}/O{sub 2}  

SciTech Connect

In plasma etching for microelectronics fabrication, the quality of the process is in large part determined by the ability to control the ion energy distribution (IED) onto the wafer. To achieve this control, dual frequency capacitively coupled plasmas (DF-CCPs) have been developed with the goal of separately controlling the magnitude of the fluxes of ions and radicals with the high frequency (HF) and the shape of the IED with the low frequency (LF). In steady state operation, plasma properties are determined by a real time balance between electron sources and losses. As such, for a given geometry, pressure, and frequency of operation, the latitude for controlling the IED may be limited. Pulsed power is one technique being investigated to provide additional degrees of freedom to control the IED. In one configuration of a DF-CCP, the HF power is applied to the upper electrode and LF power is applied to the lower electrode which is serially connected to a blocking capacitor (BC) which generates a self dc-bias. In the steady state, the value of the dc-bias is, in fact, constant. During pulsed operation, however, there may be time modulation of the dc-bias which provides an additional means to control the IED. In this paper, IEDs to the wafer in pulsed DF-CCPs sustained in Ar/CF{sub 4}/O{sub 2} are discussed with results from a two-dimensional plasma hydrodynamics model. The IED can be manipulated depending on whether the LF or HF power is pulsed. The dynamic range of the control can be tuned by the dc-bias generated on the substrate, whose time variation depends on the size of the BC during pulsed operation. It was found that high energy ions can be preferentially produced when pulsing the HF power and low energy ions are preferentially produced when pulsing the LF power. A smaller BC value which allows the bias to follow the change in charged particle fluxes produces a larger dynamic range with which to control IEDs.

Accurate equations of state for CF4, CF4Ar, and CF4CH4 fluids using two-body and three-body intermolecular potentials from molecular dynamics simulation  

Science Journals Connector (OSTI)

Abstract Molecular dynamics simulations have been performed to obtain pressures and equations of state of CF4, CF4Ar, and CF4CH4 fluids using different inversion and ab initio pair-potentials. To take many-body forces into account, the three-body potentials of Hauschild and Prausnitz, Mol. Simul. 11 (1993) 177185, Wang and Sadus, J. Chem. Phys. 125 (2006) 144509144513, and Guzman et al., Mol. Phys. 109 (2011) 955967 have been used with the pair-potentials. The significance of this work is that the many-body potential of Hauschild and Prausnitz is extended as a function of density, temperature, and molar fraction and is used with the HFD-like pair-potentials of CF4, CF4Ar, and CF4CH4 systems to improve the prediction of the pressure values without requiring an expensive three-body calculation. We have also simulated the self-diffusion coefficient of CF4 in good agreement with experimental data.

Direct measurements of methoxy removal rate constants for collisions with CH/sub 4/, Ar, N/sub 2/, Xe, and CF/sub 4/ in the temperature range 673--973K

Removal rate constants for CH/sub 3/O by CH/sub 4/, Ar, N/sub 2/, Xe, and CF/sub 4/ were measured over a 400K temperature range using a laser photolysis/laser-induced fluorescence technique. Rapid methoxy removal rates are observed for the non-reactive collision partners (Ar, N/sub 2/, Xe, and CF/sub 4/) at elevated temperatures showing that the dissociation and isomerization channels for CH/sub 3/O are indeed important. The total removal rate constant (reaction /plus/ dissociation and/or isomerization) for CH/sub 4/ exhibits a linear dependence on temperature and has a removal rate constant, k/sub r/ /equals/ (1.2 +- 0.6) /times/ 10/sup /minus/8/exp((/minus/101070 +- 350)/T)cm/sup 3/molecule/sup /minus/1/s/sup /minus/1/.

Epitaxial growth of B-doped Si on Si(100) by electron-cyclotron-resonance Ar plasma chemical vapor deposition in a SiH4B2H6H2 gas mixture without substrate heating  

Science Journals Connector (OSTI)

Abstract Characteristics of B-doped Si epitaxial growth on Si(100) by using electron-cyclotron-resonance Ar plasma enhanced chemical vapor deposition without substrate heating in a SiH4B2H6H2Ar gas mixture were investigated. B concentration in the deposited films increases with decreasing microwave power for plasma generation. At the microwave power of 125W, the B concentration increases up to 5נ1021cm?3. Deposition rate of the B-doped Si tends to be enhanced at the higher B2H6 partial pressure. Resistivity of the B-doped Si film tends to increase with decreasing the microwave power. Referring Irvin curve, in the case of 200W, the carrier concentration is estimated to be at least about 1017cm?3 at the B concentration of 1021cm?3. After heat treatment in N2 atmosphere at 200C and 300C for 2h, the resistivity drastically decreases to the value which corresponds to carrier concentration of around 1019cm?3. From Fourier transform infrared spectroscopy measurement, it is found that hydrogen incorporated in the as-deposited film desorbed by the heat treatment.

Effects of additive C{sub 4}F{sub 8} during inductively coupled BCl{sub 3}/C{sub 4}F{sub 8}/Ar plasma etching of TaN and HfO{sub 2} for gate stack patterning  

SciTech Connect

In this work, the authors investigated the etching characteristics of TaN and HfO{sub 2} layers for gate stack patterning in BCl{sub 3}/Ar and BCl{sub 3}/C{sub 4}F{sub 8}/Ar inductively coupled plasmas and the effects of C{sub 4}F{sub 8} addition on the etch selectivity of the TaN to the HfO{sub 2} layer. Addition of C{sub 4}F{sub 8} gas to the BCl{sub 3}/Ar chemistry improved the TaN/HfO{sub 2} etch selectivity because adding the C{sub 4}F{sub 8} gas enhances the formation of the CF{sub x}Cl{sub y} passivation layer on HfO{sub 2} surface and decreased the HfO{sub 2} etch rate more rapidly than the TaN etch rate in a disproportionate way. Reduction in the etch time for HfO{sub 2} layer also increases the TaN/HfO{sub 2} etch selectivity because the etch time gets closer to the initiation time for HfO{sub 2} etching.

Off-shell extrapolation of Regge-model NN scattering amplitudes describing final state interactions in 2H(e,e'p)  

SciTech Connect

In this work, an off-shell extrapolation is proposed for the Regge-model NN amplitudes presented in a paper by Ford and Van Orden [ Phys. Rev. C 87 014004 (2013)] and in an eprint by Ford (arXiv:1310.0871 [nucl-th]). The prescriptions for extrapolating these amplitudes for one nucleon off-shell in the initial state are presented. Application of these amplitudes to calculations of deuteron electrodisintegration are presented and compared to the limited available precision data in the kinematical region covered by the Regge model.

Heavy-ion induced desorption of a TiZrV coated vacuum chamber bombarded with 5 MeV/u Ar{sup 8+} beam at grazing incidence  

SciTech Connect

TiZrV nonevaporable getter (NEG) coated vacuum chambers is a new vacuum technology which is already used in many particle accelerators worldwide. This coating is also of interest for heavy-ion accelerator vacuum chambers. Heavy-ion desorption yields from an activated as well as a CO saturated NEG coated tube have been measured with 5 MeV/u Ar{sup 8+} beam. The sticking probability of the NEG film was obtained by using the partial pressure ratios on two sides of the NEG coated tube. These ratios were compared to results of modeling of the experimental setup with test particle Monte Carlo and angular coefficient methods. The partial pressures inside the saturated NEG coated tube bombarded with heavy ions were up to 20 times larger than those inside the activated one. However, the partial pressure of methane remained the same. The value of the total desorption yield from the activated NEG coated tube is 2600 molecules/ion. The desorption yields after saturation for CH{sub 4}, H{sub 2}, and CO{sub 2} were found to be very close to the yields measured after the activation, while CO increased by up to a factor of 5. The total desorption yield for the saturated tube is up to 7000 molecules/ion. The large value of the desorption yield of the activated NEG coated tube, an order of magnitude higher than the desorption yield from a stainless steel tube at normal incident angle, could be explained by the grazing incident angle.

Inductively coupled plasmareactive ion etching of c- and a-plane AlGaN over the entire Al composition range: Effect of BCl{sub 3} pretreatment in Cl{sub 2}/Ar plasma chemistry  

SciTech Connect

Inductively coupled plasma (ICP)reactive ion etching (RIE) patterning is a standard processing step for UV and optical photonic devices based on III-nitride materials. There is little research on ICP-RIE of high Al-content AlGaN alloys and for nonpolar nitride orientations. The authors present a comprehensive study of the ICP-RIE of c- and a-plane AlGaN in Cl{sub 2}/Ar plasma over the entire Al composition range. The authors find that the etch rate decreases in general with increasing Al content, with different behavior for c- and a-plane AlGaN. They also study the effect of BCl{sub 3} deoxidizing plasma pretreatment. An ICP deoxidizing BCl{sub 3} plasma with the addition of argon is more efficient in removal of surface oxides from Al{sub x}Ga{sub 1?x}N than RIE alone. These experiments show that Al{sub x}Ga{sub 1?x}N etching is affected by the higher binding energy of AlN and the higher affinity of oxygen to aluminum compared to gallium, with oxides on a-plane AlGaN more difficult to etch as compared to oxides on c-plane AlGaN, specifically for high Al composition materials. The authors achieve reasonably high etch rate (?350 nm/min) for high Al-content materials with a smooth surface morphology at a low DC bias of ??45 VDC.

Modelling of radiative divertor operation towards detachment in experimental advanced superconducting tokamak  

SciTech Connect

In order to actively control power load on the divertor target plates and study the effect of radiative divertor on plasma parameters in divertor plasmas and heat fluxes to the targets, dedicated experiments with Ar impurity seeding have been performed on experimental advanced superconducting tokamak in typical L-mode discharge with single null divertor configuration, ohmic heating power of 0.5 MW, and lower hybrid wave heating power of 1.0 MW. Ar is puffed into the divertor plasma at the outer target plate near the separatrix strike point with the puffing rate 1.26 Multiplication-Sign 10{sup 20} s{sup -1}. The radiative divertor is formed during the Ar puffing. The SOL/divertor plasma in the L-mode discharge with radiative divertor has been modelled by using SOLPS5.2 code package [V. Rozhansky et al., Nucl. Fusion 49, 025007 (2009)]. The modelling shows the cooling of the divertor plasma due to Ar seeding and is compared with the experimental measurement. The changes of peak electron temperature and heat fluxes at the targets with the shot time from the modelling results are similar to the experimental measurement before and during the Ar impurity seeding, but there is a major difference in time scales when Ar affects the plasma in between experiment and modelling.

Cm3 detector neutrino science: search for neutrino oscillations in electron Cm3 detector neutrino science: search for neutrino oscillations in electron capture decay Paul Vetter LBNL Abstract: A recent publication from a group at GSI (arXiv:nucl-ex/0801.2079) claimed to observe time oscillation of the decay rate of electron capture isotopes. They attributed this effect to neutrino species mixing which caused a superposition of neutrino mass states to contribute to the decay rate. A model, expanded in other arXiv papers argued that the different neutrino mass states produce interference in the calculation of the decay rate for the two-body electron capture decay. The well-measured oscillation frequency was calculated to be proportional to the neutrino mass difference squared, $\Delta m_{12}2$. If correct, this interpretation could revolutionize the study of neutrino mixing. A small

Comments on the report "Indications of anomalous heat energy production in a reactor device containing hydrogen loaded nickel powder" [arXiv:1305.3913] by G.Levi, E.Foschi, T.Hartman, B.Histad, R.Pettersson, L.Tegnr, H.Essn  

E-Print Network (OSTI)

In a recent report titled "Indications of anomalous heat energy production in a reactor device containing hydrogen loaded nickel powder" and published on arXiv, G. Levi and co-workers put forth several claims concerning the operations and performance of the so-called E-Cat of inventor Andrea Rossi. We note first of all that the circumstances and people involved in the test make it far from being an independent one. We examine the claims put forth by the authors and note that in many cases they are not supported by the facts given in the report. We present results from thermal calculations showing that alternative explanations are possible were the authors seem to jump to conclusions fitting pre-conceived ideas. In general we find that much attention is drawn to trivialities, while important pieces of information and investigation are lacking and seem not to have been conducted or considered. We also note that the proposed claims would require new physics in not only one but several areas. Besides a cold-fusion like process without production of any radiation also extreme new material properties would be needed to explain what rather seems to be a problem of correct measurement. Therefore, it is clear to us that a truly independent and scientific investigation of the so called E-Cat device, convincingly demonstrating an "anomalous heat energy production" has not been presented in the arXiv report and is thus, to-date, still lacking.

In a recent report titled "Indications of anomalous heat energy production in a reactor device containing hydrogen loaded nickel powder" [arXiv:1305.3913], G. Levi and co-workers put forth several claims concerning the operations and performance of the so-called E-Cat of Andrea Rossi. We note first of all that the circumstances and people involved in the test make if far from being an independent one. We examine the claims put forth by the authors and note that in many cases they are not supported by the facts given in the report. The authors seem to jump to conclusions fitting pre-conceived ideas where alternative explanations are possible. In general we find that much attention is drawn to trivialities while important pieces of information and investigation are lacking and seem not to have been conducted or considered. These are characteristics more typically found in pseudo-scientific texts and have no place in a technical/scientific report on this level. We also note that the proposed claims would require...

GSI Oscillations as Interference of Neutrino Flavour Mass--Eigenstates and Measuring Process  

E-Print Network (OSTI)

This paper is addressed to the proof of the important role of measuring apparatus, i.e. the measuring process, in the formation of necessary and sufficient conditions for the explanation of a time modulation of K-shell electron capture (EC) decay rates of hydrogen-like (H-like) heavy ions (or the GSI oscillations) as the interference of neutrino mass-eigenstates of the electron neutrino constituents. For our analysis we use a toy-model, which has been recently proposed by Peshkin arXiv: 1403.4292 [nucl-th] for a verification of the mechanism of the GSI oscillations as the interference of neutrino mass-eigenstates by Ivanov and Kienle Phys. Rev. Lett. 103, 062502 (2009).

Determination of the 3He+alpha\\to 7Be asymp. normalization coefficients (nucl. vertex constants) and their application for extrapolation of the 3He(alpha,gamma)7Be astroph. S-factors to the solar energy region

A new analysis of the modern precise measured astrophysical $S$ factors for the direct capture $^3He(\\alpha,\\gamma)^7{\\rm {Be}}$ reaction [B.S.

New estimates are obtained for the $^{\\glqq}$indirectly determined\\grqq\\, values of the asymptotic normalization constants (the nuclear vertex constants) for $^3{\\rm {He}}+\\alpha\\to{\\rm {^7Be}}$(g.s.) and $^3{\\rm {He}}+\\alpha\\to{\\rm {^7Be}}$(0.429 MeV) as well as the astrophysical $S$ factors $S_{34}(E)$ at E$\\le$ 90 keV, including $E$=0.

The Woods--Saxon potential form is used for the bound ($\\alpha+^3{\\rm {He}}$)- state and the $^3{\\rm {He}}\\alpha$- scattering wave functions. New estimates are obtained for the "indirectly measured", values of the asymptotic normalization constants (the nuclear vertex constants) for $^3{\\rm {He}}+\\alpha\\to^7{\\rm {Be}}(g.s.)$ and $^3{\\rm {He}}+\\alpha\\to^7{\\rm {Be}}(0.429 MeV)$ as well as the astrophysical $S$-factors $S_{34}(E)$ at E$\\le$ 90 keV, including $E$=0.
