Relative intensities of shake-up satellites in photoionization of potassium atoms from 3p64s and 3p64p

Abstract

Photoionization cross sections for the 3p subshell electrons, correlation shake-up and conjugate shake-up satellite transitions in a relaxed-orbital Hartree-Fock framework within the dipole approximation are calculated. The potassium atom in the ground and first excited state 3p64p2P is considered. The single-configuration approach using pure LS and intermediate coupling of electron momenta is applied. The strong enhancement of the relative intensity of the shake-up correlation satellites in 3p inner-shell photoionization of the 3p64p2P excited state was obtained with respect to similar processes for the K atom in the ground state.
