英文摘要Via a differential comparison of the binding energies between H- and He-like ions, the electronelectron interaction energies of the states 1s2, (1s, 2s)0,1, (1s, np1/ 2)0,1, (1s, np3/ 2)1,2, (2s, np1/ 2) 0,1 and (2s, np3/ 2) 1,2 (n. 5) in the He-like isoelectronic sequence are obtained over a wide range of the nuclear charge Z = 2 - 133 by using fully relativistic multiconfiguration Dirac-Hartree-Fock and configuration interaction methods. Contributions from the Coulomb and Breit interactions, the nuclear effects, the self-energy and vacuum polarization corrections are evaluated. The results show that, the one-electron corrections to the electron-electron interaction are nearly cancelled out during the deduction of the interelectron interaction energies. Besides the Coulomb interaction, the Breit interaction plays a significant role in the electronelectron interaction for high-Z ions; it contributes 23% of the electron-electron interaction energy at Z = 133.
