摘要
把Ｒ．Ｍｏｒｅ屏蔽氢模型中的内、外屏蔽概念融于Ｓｌａｔｅｒ单电子屏蔽模型之中，由此给出了具有内、外屏蔽概念的单电子势函数，在内屏蔽电荷的基础上引入相对论修正项，其中量子修正Δｎｌ的值可从等电子系列实验抛物线公式中推算出来，从上述几方面改进了屏蔽氢离子模型。大量计算结果表明，改进的屏蔽氢离子模型可较好地计算出离子的电离势，尤其是对高Ｚ高离化离子的电离势和次壳层能量改进模型计算的结果能与ＭＣＤＦ的结果相符。
In the present paper, the inner screened charge and outer screened charge in R.M. More's screened hydrogenic ionization model are introduced into Slater's one electron model, and the potential function with inner and outer screened conception is given. The values of Δ nl are obtained from experimental parabolic curve of the isoelectronic series of atoms and ions with same electronic state, and the relativistic effects are also taken into account on inner screened charge. The number of calculation results show that the ionization potentials can be obtained with high accuracy from the improved model, and the improved model can calculate subshell energy of high Z and high ionization ions more accurately.
