摘要
Based on the multiconfiguration Dirac-Hartree-Fock method, the field shift and mass shift parameters of the 1s(2) S-1(0) - 1s 2p P-1(1)0 and 1s(2) S-1(0) - 1s 2p P-3(0,1,2)0 transitions in He-like ions for the sequence 2 <= Z <= 83 are calculated with high precision. The total value of the isotope shift is determined by the sum of the mass- and field-shifts. With the inclusion of the Breit interaction and the leading QED corrections, we find that the mass shift parameters of these transitions do not change monotonously along the isoelectronic sequence in the high-Z range due to the relativistic nuclear recoil effects. In addition, the field shifts and mass shifts of these four transitions are estimated and compared along the isoelectronic sequence.
