Photoionization cross-section of 4s~24p~6 shells in the vicinities of the 4s4p~6np autoionizing resonances in Kr isoelectronic sequence

摘要

The results of many electron calculations of photoionization cross section in Kr isoelectronic sequence are presented. The resonance structure associated with excitation of autoionizing 4s4p~6np states has been studied with account for the dynamic many electron correlations. Double-electron excitations are shown to play a crucial role in describing of resonance shapes.
