摘　　要：利用全实加关联方法获得类锂离子体系1s2 nl从LiⅠ到NeⅧ(2≤n≤5,l=s,p,d,f)激发态的波函数,利用所获得的波函数求得电子在核处密度算符的期待值.根据原子核体积效应对能级结构修正公式获得原子核体积效应对类锂离子体系激发态能级结构的影响.为获得高精度三电子体系能谱提供理论数据参考.The wave functions of the excited states 1s^2nz form LiI到NeⅧ（2≤N≤5,l=s,p,d,f） was investigated with a method of full core plus correlation. Then, the charge density of the excited states for the lithium-like ions at the nucleus was calculated. The calculations of the finite nuclear size effects are performed with the Fermi model of the nuclear charge distribution. The finite nuclear size effect becomes important for ions with higher nuclear charge.
