摘要/Abstract

Abstract: The mass-and field-shift parameters of the two 2s ²S_1/2 $\rightarrow$ 2p ²P_1/2,3/2 transitions in the Li-like Ca ions are calculated by using multi-configuration Dirac-Hartree-Fock (MCDHF) and the relativistic configuration interaction (RCI) methods with the inclusion of the transverse photon (Breit) interaction, vacuum polarization and self-energy corrections. In addition, the mass shift and field shift of these two transitions are calculated, where the field shift is calculated by using the evaluated value $\delta\langle r^2\rangle$ obtained by [Atomic Data and Nuclear Data Tables 9969 (2013)]. It is found that the mass shift of Li-like Ca ions is greater than the field shift.

Key words: isotope shift, multi-configuration Dirac-Hartree-Fock (MCDHF), mass shift, field shift
