Angular distribution in resonant Auger spectra of xenon excited below the3d5/2ionization threshold

Abstract

The ${3d}_{5/2}\to$ $6p$ and $7p$ excitations and their decay in Xe have been studied by using total ion yield and angle-resolved electron spectroscopies. The natural linewidths of the ${3d}_{5/2}^{-1}\mathrm{np}\mathrm{}(n=6,7\mathrm{})\mathrm{}$ states were determined. Anisotropy parameters of resonant Auger transitions to ${4d}^{-2}\mathrm{np}\mathrm{}(n=6,7\mathrm{})\mathrm{}$ final states were extracted from the experiment. They were found to be connected with the anisotropy parameters of the corresponding normal Auger transitions as predicted by the gross spectator model.
