The mass- and field-shift parameters of the two 2s 2S1/2 → 2p 2P1/2,3/2 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 δ〈 r 2〉 obtained by [Atomic Data and Nuclear Data Tables 99 69 (2013)]. It is found that the mass shift of Li-like Ca ions is greater than the field shift.
