Excitation of Ar3p54s−3p54ptransitions by electron impact

Argon 4sand 4pExcited States Atomic Data Applied in ARC-JET Modeling

“…In this figure, we compare DW results obtained with three configurations and with eight configurations to Born approximation and RDW [27] results. Available theoretical results [19,28,29] are also shown in the figure, only for energies higher than 5 eV. The presented experimental data from two experiments of Boffard et al [30,31] and one of Piech et al [32] are in rather good agreement with calculations.…”

Angular Momentum Partitioning and Hexacontatetrapole Moments in Impulsively Excited Argon Ions

“…Electron-atom scattering is a prototype of the manybody long-range force problem. Our understanding of collisions with H, He, and the light alkali atoms is good [1][2][3], but calculations of scattering from the heavy noble gases are not yet satisfactory [4][5][6][7][8][9][10]. This is due primarily to the outer p-shell configuration in such atoms and the fact that relativistic effects can be important in certain collision channels.…”

Electron impact excitation of xenon from the metastable state to the excited states

“…Thus, those cross sections are of high interest for the analysis of photon emissions from low temperature plasmas and applications in the fields of gas-discharge lasers, Hg-free fluorescent lighting and plasma displays [1][2][3][4]. During the past 10 years, a number of theoretical and experimental studies have been carried out on the metastable state excitations of neon, argon and krypton [5][6][7][8][9][10][11][12][13]. However, the electron impact excitation process of xenon, which usually serves as a typical example in the study of electron collision with heavy elements, is still highly challenging because of strong correlation and relativistic effects.…”
