Abstract

New results of many electron calculations of 4p-subshell photoionization cross section for Kr, Rb⁺, Sr²⁺, and Y are presented. The resonance structure associated with excitation of autoionizing 4s4p⁶np states has been studied. The dynamic polarization and screening effects are taken into account for calculations of resonance parameters. Double-electron excitations is shown to play a crucial role in describing the resonance shapes and widths.
