Abstract

The effects of relativistic small radial component on atomic photoionization cross sections have been studied within relativistic average selfconsistent field theory. Relativistic effects are relatively unimportant for low photon energy, along with a review of highenergy photoionization the relativistic effects are quite important. The effects of relativistic small radial component on photoionization process should show breakdown when the nuclear finitesize effects is taken into account. The compression of wavefunction into the space near nucleus is so strong in highly charged ions that the electronic radius greatly decreases, and the effects of relativistic small radial component on photoionization cross sections turn to stronger than ordinary atoms. Since relativistic effects are extremely sensitive to the behavior of small radial component, the results are in good agreement with relativistic effects on photoionization cross section.
