Calculations have been performed for the photoionization of the Ne 2p, Ar 3p, Kr 4p, and Xe 5p isoelectronic sequences using both multiconfiguration Hartree-Fock and Hartree-Slater wave functions. The results show that away from the vicinity of a Cooper minimum, which moves rapidly into the discrete in going along an isoelectronic sequence, agreement between the two calculations is quite good. Thus we conclude that for highly stripped ions, the Hartree-Slater results are an excellent approximation to the multiconfiguration Hartree-Fock photoionization cross sections. (AIP)
