Electron correlation in the 4d−16p→5s−26p and 5s−15p−16p resonance Auger transitions of Xe

The Xe 4d−16p→5s05p66p and 5s15p56p resonant Auger transitions have been studied both theoretically and experimentally. High resolution resonant Auger spectra have been recoded with different photon bandwidths which have enabled to separate the first step Auger transition from the overlapping second step transitions. Theoretical calculations using multi-configuration Dirac-Fock approach with different configuration expansions were carried out, compared to each other and to the experiment. The calculations with the largest basis set were found to reproduce the distribution of the intensity to the main and satellite lines in both the 5s05p66p and 5s15p56p Auger groups reasonably well, and to predict the structure of the 4d−16p→5s05p66p main lines very well.
