Auger-electron spectrum of atomic cesium in the 15-75-eV energy range

Abstract

Auger-electron spectrum of Cs in the 15-75-eV energy region following 20 keV electron impact is presented. The most intensive structures in the spectra are analyzed by comparing their energies with the calculated energies of the Auger transitions applying a multiconfiguration Dirac-Fock method. Also the free-atom binding energies $E_B\left(N_5\right)=\mathrm{82.79.}\mathrm{}\pm 0.10$ eV and $E_b\left(N_4\right)=85.07\mathrm{}\pm 0.10$ eV are obtained with the aid of optical double-hole final-state energy levels.
