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〈 r2〉 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. [ABSTRACT FROM AUTHOR]
