摘要
本文给出了在自洽场近似下,入射光子能量在x射线范围内(132.3～1500eV),使用相对论及非相对论计算AlI及UI原子壳层光电离截面及总截面。讨论了相对论效应及辐射场的多极展开对光电离截面数值的影响。
Subshell and total Photoionization cross sections for All and UI were calculated for 13 incident photon energies corresponding to X-ray lines in the energy range 132.3~1500eV. In this calculation, the electrons are treated relativistically and non-retativistically, and as moving in a Hartree-Slater central potential. Relativistic effects on photoionization are discussed, and the influence on the magnitute of the cross sections of all multipoles of the radiation field also.
