Isotope shift calculations for D lines of stable and short-lived lithium nuclei*

The isotope shifts (ISs) for the 2s(2)S(1/2) to 2p(2)PJ (J = 1/2, 3/2) transitions of the lithium nuclei including the stable and short-lived isotopes are calculated based on the multi-configuration Dirac-Hartree-Fock method and the relativistic configuration interaction approach. The results are in good agreement with the previous theoretical and experimental results within a deviation less than 0.05%. The methods used here could be applied to the IS calculations for other heavier Li-like ions and few-electron systems.
