Efficient wavelength tuning from 446 to 524nm with a minimum spectral linewidth of lnm was demonstrated for an electron beam pumped XeF(C~A) laser. Energy densities of 0.1 J/1 were obtained for an optimized Ar/Kr/Xe/Fz/NFa mixture.
We have measured full momentum images of electrons rescattered from Xe, Kr, and Ar following the liberation of the electrons from these atoms by short, intense laser pulses. At high momenta the spectra show angular structure (diffraction) which is very target dependent and in good agreement with calculated differential cross sections for the scattering of free electrons from the corresponding i...
Introduction: Recently we made successful measurements of all solar wind (SW) krypton isotopes in Genesis Al-collectors [1]. Here we report results of 20 independent analysis of Xe extracted from Aluminum on Sapphire (AloS) under four different experimental conditions. Experimental: Separation of the solar wind heavy noble gases, captured in Genesis collectors, from surface and possible interfa...
The interaction of atomic and molecular species with water and ice is of fundamental importance for chemistry. In a previous series of publications, we demonstrated that translational energy activates the embedding of Xe and Kr atoms in the near surface region of ice surfaces. In this paper, we show that inert molecular species may be absorbed in a similar fashion. We also revisit Xe embedding,...
Thermodynamic properties of bcc uranium with point defects are studied using ab initio molecular dynamics (MD) simulations at 1100 K. The were performed canonical ensembles ${\mathrm{U}}_{127}{\mathrm{M}}_{1}$, ${\mathrm{U}}_{128}{\mathrm{M}}_{1}$, and ${\mathrm{U}}_{126}{\mathrm{M}}_{1}{\ensuremath{\square}}_{1}$ for M = $\ensuremath{\square}$, He, Ne, Ar, Kr, Xe, Sr, Zr, I, Cs, Pu disposed on...
