The theoretical study on the decay processes of the 4d core excited states of Cs Ⅳ

Abstract

By including the electron correlation and the relaxation effects,the energy level structures of the 4d core excited configuration 4d9 5s25p5,final radiative configuration 4d105s25p4 and final Auger configurations 4d105s25p3 and 4d105s15p4 of the Cs Ⅳ ion and all possible decay dynamic processes related to these configurations are systematically studied using multi-configuration Dirac-Fock method. The present study not only provides satisfactory results for the radiative transition energies,oscillator strengths and line widths in comp arison with the existing semi-empirical calculations and related experiments,but also predicts some dominant features of the Auger electron spectrum emitted by the Auger decay process of the 4d95s25p5 core excited states.
