Title: 2s photoionization of Na and 3s photoionization of K atoms in the ground and first excited states
Abstract: Cross sections of single and shake-up photoionization from the subvalence s subshell of sodium and potassium atoms are calculated. The relaxed-orbital multiconfiguration and single-configuration Hartree - Fock approaches are applied to the atoms in the ground state and in the first excited state . A strong enhancement of the ratio of cross sections of shake-up photoionization to those of single photoionization of the atoms in the excited state was obtained as compared with the same process for the atoms in the ground state.
