Photoionization cross section for the 4s subshell of Zn I

Research output: Contribution to journalArticlepeer-review


We present a calculation of the photoionization cross section for the 4s subshell of neutral zinc using many-body perturbation theory. The cross section is strongly affected by correlations among 4s and 3d electrons. Resonances due to the 3d94s2np configurations dominate the cross section and are split by the spin-orbit interaction. We have also included interactions between resonances. Correlations reduce the Hartree-Fock cross section by an order of magnitude near threshold. Our results are in qualitative agreement with the experimental data of Marr and Austin.
