Auger Spectra and Different ionic Charges Following 3s, 3p and 3d sub-shells Photoionization of Kr atoms

The de-excitation following a deep core hole generation in atom gives rise to emission of radiative and Auger spectra and to different ionic charges. Auger transition spectra followed M sub-shells ionization of Kr is calculated using simulation technique. The successive radiative and Auger transitions lead to stable holes in the outer-shells of atoms. The cascade branches following 3s, 3p and 3d sub-shells ionization of Kr are discussed. The generation of spectator vacancies in the course of de-excitation cascades following primary vacancy leads to Auger satellite spectra. The last transition in each branch of the de-excitation produces ion of a specific charge. Radiative and Auger transitions are obtained using Dirac-Fock-Slater wave functions. The results of different ionic charges agree well with the experimental.
