| 摘 要： | 通过自洽迭代求解Hartree方程得到各组态下的轨道波函数。以此构造组态波函数为基矢，对氦Rydberg态1snd组态的^1D—^3D谱项分裂值进行了多体微扰计算，计算结果与实验结果符合得较好。对于由同科电子构成的组态，由于没有相应的^3D谱项，所以由此计算得到的二级以上单态、三重态的能级修正值是不对称的。

| Abstract: | Self-consistent iteration of Hartree equation is used to obtain orbital wave functions for (different) configurations. These functions build up the basis for ~1D-~3D splittings MBPT calculation of helium 1snd Rydberg states, and the results agree well with the experiments. Due to the lack of ~3D terms in some configurations composed of equivalent electrons, the second- and higher-order corrections for ~1D are asymmetric to those for ~3D. |
