“…We note that the fraction of triply charged ions is under-predicted for both profiles. The reason for this phenomenon is unknown at the moment since an analysis of the cross sections used in our model [40][41][42] does suggest that the measured fraction of triply charged ions is not possible provided the plasma conditions in the thruster. The existence of metastable states that require less energy for ionization can be a possible cause for this phenomenon that will be investigated in the future.…”

“…Although electron-impact ionization cross sections have been measured for Xe [6], Xe + [7-10], Xe 2+ [10,11], Xe 3+ [10,12], Xe 4+ [10], Xe 6+ [13], and Xe 8+ [14,15], they are all too low in charge state to be influenced by radiative decay effects. Therefore, as an example of the influence of radiative decay effects and in support of current experiments [16], we calculate the electron-impact single ionization of the 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 ground configuration of Xe 24+ . We examine the effects of radiative decays on contributions from direct ionization, excitation-autoionization, and resonantcapture double autoionization.…”

Configuration-average distorted-wave calculations are carried out for the electron-impact single ionization of Xe24 +. Contributions are included from direct ionization of the 3s, 3p, 3d and 4s subshells and from indirect ionization via 3s → nl, 3p → nl and 3d → nl excitations followed by autoionization. Branching ratios are found for single versus double ionization of the 3s and 3p subshells and for autoionization versus radiative decay of all 3l → nl excitations. Additional distorted-wave and R-matrix calculations find resonant-capture double-autoionization contributions to be quite small. The total ionization cross section for Xe24 + is found to be dominated by indirect excitation–autoionization contributions, especially near the single-ionization threshold. An approximate 15% reduction in the total ionization cross section is found due to the radiative decays included in the branching ratios.

Gas Lasers are important tools that are used in variety purposes, for their low and (cw) output power. The aim of this study was to prepare a way to calculate an optimum stimulated emission cross-section in a gas laser containing a mixture of Xenon and Neon by (30%-70%). The process was a theoretical study of each gas in separate in terms of their physical properties as an active medium. The results of these calculations are logic and more convenient than other mixtures used before
