摘　　要：通过自洽迭代求解Hartree方程,得到了氦原子1snl组态下的严格数值解波函数,以此构造LS耦合谱项(支项)波函数作为基矢.采用线性变分法,同时考虑交换作用和Breit-Bethe近似下的磁相互作用项,计算了氦Rydberg态10G—10M系列能级的磁精细结构,计算结果很好地符合已有的实验值.对计算方法的进一步改进提出了设想和讨论.With self-consistent iterative method for solving the Hartree equation, precise numerical wavefunctions of helium lsnl configuration are generated to build up the LS term wavefunctions as basis sets. The magnetic fine structure of helium 10G-10M Rydberg states is calculated with the linear variation method, including both the exchange and magnetic interaction under the Breit-Bethe approximation. The calculated results agree well with the existing experiment data. Some ideas and discussions for further improvement are given.
