  • A sensitive search for isotopes of a superheavy element (SHE) in natural gold materials has been performed with accelerator mass spectrometry at the Vienna Environmental Research Accelerator, which is based on a 3-MV tandem accelerator. Because the most likely SHE in gold is roentgenium (Rg, Z = 111), the search concentrated on Rg isotopes. Two different mass regions were explored: (i) For the neutron-deficient isotopes {sup 261}Rg and {sup 265}Rg, abundance limits in gold of 3x10{sup -16} were reached (no events observed). This is in stark contrast to the findings of Marinov et al.[Int. J. Mod. Phys. E 18, 621more » (2009)], who reported positive identification of these isotopes with inductively coupled plasma sector field mass spectrometry in the (1-10)x10{sup -10} abundance range. (ii) Theoretical models of SHEs predict a region of increased stability around the proton and neutron shell closures of Z = 114 and N = 184. We therefore investigated eight heavy Rg isotopes, {sup A}Rg, A = 289, 290, 291, 292, 293, 294, 295, and 296. For six isotopes no events were observed, setting limits also in the 10{sup -16} abundance range. For {sup 291}Rg and {sup 294}Rg we observed two and nine events, respectively, which results in an abundance in the 10{sup -15} range. However, pileup of a particularly strong background in these cases makes a positive identification as Rg isotopes--even after pileup correction--unlikely.« less
  • A series of neutral, dinuclear gold(I) complexes, containing phosphine and thiolate ligands, have been studied by EXAFS and luminescence spectroscopy. Gold(I)-gold(I) interactions are detected for the first time by EXAFS studies on solid samples at liquid helium temperature. A strong, distinct peak at 1.90 {+-} 0.02 {angstrom}, assigned to Au-P and Au-S bonds, appears in the Fourier transform for complexes 1-8. A less intense peak appears for complexes 2-6 at 2.8 {angstrom} with the amplitude maximizing toward high k characteristic of a gold backscattering atom. The calculated EXAFS results indicate gold(I)-gold(I) distances ranging from 3.0 to 3.2 {angstrom} for complexesmore » 2-6. In contrast, no gold(I)-gold(I) interactions are detected for complexes 1, 7, and 8. The Au-Au and Au-P(S) distances calculated by EXAFS are similar to those measured by X-ray diffraction. All of the neutral, dinuclear gold(I) complexes luminescence at room temperature in the solid state. The Stokes shifts average 6 x 10{sup 3} cm{sup {minus}1} and are indicative of a large distortion in the excited state compared to the ground state. Spectral acquisition using time delays of 10-50 {mu}s confirms the phosphorescent nature of the emission. The origin of the luminescence of complexes 1-8 is consistent with a S {yields} Au CT excited state that is perturbed by substituent electronic effects leading to the red shift in emission for 5-8 relative to 1-4. There is no correlation between gold(I)-gold(I) bonding and the energy or band shape of the excitation and emission of 1-8. The luminescence and EXAFS results taken together demonstrate that a gold(I)-gold(I) interaction is not a necessary condition for luminescence. Further, the presence of a gold(I)-gold(I) interaction does not significantly perturb the luminescence in this series of gold(I) complexes.« less
  • Continental-scale convection-permitting simulations of the warm seasons of 2011 and 2012 reproduce realistic structure and frequency distribution of lifetime and event mean precipitation of mesoscale convective systems (MCSs) over the central United States. Analysis is performed to determine the environmental conditions conducive to generating the longest-lived MCSs and their subsequent interactions. The simulations show that MCSs systematically form over the Great Plains ahead of a trough in the westerlies in combination with an enhanced low-level jet from the Gulf of Mexico. These environmental properties at the time of storm initiation are most prominent for the MCSs that persist for themore » longest times. Systems reaching 9 h or more in lifetime exhibit feedback to the environment conditions through diabatic heating in the MCS stratiform regions. As a result, the parent synoptic-scale wave is strengthened as a divergent perturbation develops over the MCS at high levels, while a cyclonic circulation perturbation develops in the midlevels of the trough, where the vertical gradient of heating in the MCS region is maximized. The quasi-balanced mesoscale vortex helps to maintain the MCS over a long period of time by feeding dry, cool air into the environment at the rear of the MCS region, so that the MCS can draw in air that increases the evaporative cooling that helps maintain the MCS. At lower levels the south-southeasterly jet of warm moist air from the Gulf is enhanced in the presence of the synoptic-scale wave. That moisture supply is essential to the continued redevelopment of the MCS.« less
