| Popis: | The Xe 4 d − 1 6 p → 5 s 0 5 p 6 6 p and 5 s 1 5 p 5 6 p 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 5 s 0 5 p 6 6 p and 5 s 1 5 p 5 6 p Auger groups reasonably well, and to predict the structure of the 4 d − 1 6 p → 5 s 0 5 p 6 6 p main lines very well. |
