摘要：

Relativistic central-field (Dirac-Slater) calculations of photoionization of atoms and ions have been performed. The results show that the photoionization cross sections for inner-shell njl electrons are largely unaffected by removal of outer shell electrons (with principal quantum number greater than n) except for a shift in threshold, just as in the non-relativistic case. The most dramatic results are obtained for Th(Z=90) compared with Th80+ where σ(hv) remains almost constant through 80 stages of ionization. The results are explained in terms of the fact that 〈r〉 is primarily a function of principal quantum number. © 1979.
