| 摘 要： | 用变分微扰论计算了氦原子1S2S态两个能级的能量.先用单参数变分法计算,再进行二级微扰计算,改进了纯微扰论的结果,得到的能量值与实验数据较好相符.

| Abstract: | The energies of 1S2S states of Helium atom are calculated by variational-perturbation method.The energies are calculated firstly by the variational method and then by the second-order perturbation theory.The results are superior to pure perturbation theory,and match well with the experimental data. |
