Experimental and theoretical study of the cascade Auger transitions in Kr and Xe

The Auger cascade processes following the Kr 3d{sub 5/2}{yields}5p and Xe 4d{sub 5/2}{yields}6p excitations have been studied both theoretically and experimentally. Experimental spectra have been measured with high photon and electron energy resolutions and the results have been compared with theoretical predictions obtained by multiconfiguration Dirac-Fock (MCDF) method. The MCDF approach is able to reproduce well the cascade process of Kr, but strong discrepancies are observed in the case of Xe. Some possible reasons for that are discussed.
