| 摘 要： | 对锂原子的四体问题的哈密顿算符进行幂级数展开，通过计算原子实的 极化(包括偶极矩，四极矩至八级电极矩)对能级的贡献，同时考虑相对论效应和LS耦合以 及有效势的高阶修正，求得了锂原子里德伯态的能级位移和能级公式。用此公式计算N=5～1 2，L=4～9，J=L±1/2的相关的精细结构位移以及能级间隔，并与有关实验结果进行了比较 。

| Abstract: | TheHamlitonian of four-body problem for lithium atom is expanded in series. The level shiftand level formula of lithium atom in Ryd berg states are achieved by means of thecalculation of polarization of the atom ic core(including the contribution of dipole,quadrupole and octapole component) ; meanwhile, the relation theory effect, the LScoupling and high order corr ecti on of the effective potential to level shift areconsidered. The fine structure splitting(N=5—12,L=4—9,J=L±1/2) and level intervals inRydberg states hav e been calculated by the mentioned formula and compared with recentexperiments data. |

| Keywords: | the levels in Rydber states the polarization of atomic core energy level shift level interval fine structure |
