【Abstract】 The specific mass shifts of the ground state, ls22s, and excited states, ls2nl (l=s, p, d, fand n≤5), for the lithium isoelectronic sequence from Z=3 to 10 were calculated by using the fullcore plus correlation wavefunctions. Our results were compared with the existing experimental and theoretical data in literature. Their agreement is fairly good. Our results for ls24p and ls25p states of 6,7Li support the recent experimentally extrapolated values. They indicate that the full-core plus correlation method is particularly suitable for calculating this quantity which is very sensitive to electron correlation effects.更多还原
