| Abstract: | 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. |
