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.
