Ion production by cascade Auger transitions following the Xe 4d−1 → 6p excitation

Abstract

Cascade Auger transitions following the Xe 4d → 6p excitation have been studied both experimentally and theoretically. The low kinetic energy part from 2 to 30 eV of the resonance Auger spectra has been recorded with different photon bandwidths which have enabled us to separate most of the first and second step Auger transitions from each other. The results for ion production obtained from the electron spectra are compared with the results of the partial ion yield spectra. The present theoretical results based on multiconfiguration Dirac–Fock (MCDF) approach are compared with the experimental findings and with earlier theoretical results. The discrepancies between the electron and ion data reported previously were found to originate from the difficulties in the treatment of the Auger group rates.
