Abstract

In recent years considerable effort has been expended in the calculation of accurate atomic photoionization cross sections. Interestingly, it has proved necessary to proceed far beyond the simplest Hartree-Fock approximation (HFA) to achieve this goal. The most extensive calculations to date have employed either the random phase approximation with exchange (RPAE)1 or many-body perturbation theory (MBPT)2. Both of these approaches build systematically on standard Hartree-Fock theory and yield results which are generally in excellent agreement with experiment.
