Abstract

Results of many electron calculations of 3p-subshell photoionization cross section for neutral potassium and calcium are presented. Resonance structure associated with excitation of autoionizing 3s3p⁶4s^1,2np states has been studied. The dynamic polarization and screening contribution to resonance parameters has been taken into account. A crucial role of double-electron excitations has been shown.
