从Hartree-Slater(H-S)自洽场理论出发,考虑了H-S自洽场理论所忽略的残余作用。以Ne原子和Ne+离子K壳层近阈光电离截面及其比值的计算为例,讨论了残余作用的影响,并和实验进行了比较。Based on the Hartree-Slater self-consistent field theory, we considere the residual interaction which is omitted in obtaining the Hartree-Slater self-consistent field in previous calculation. We calculate the near threshold photoionization cross sections of K-shell of atomic Ne-and Ne+ ion and the cross section ratios as examples. We discuss the effects of residual interaction and compare our results with experiments.
