Cascade Auger transitions following Cs 4d−15/26p excitation and Cs 4d ionization

Abstract

Auger electron and partial ion yield spectra of atomic Cs have been measured at the 4d−15/26p excitation resonance and above the 4d ionization threshold using monochromatized synchrotron radiation. The ion production obtained from the electron spectra is compared with the results of the partial ion yield spectra. The experimental findings are compared with the theoretical predictions obtained using the multiconfiguration Dirac–Fock approach and with results for the neighbouring closed-shell atom, Xe.
