Quantum Electrodynamic Calculation of Interelectron Interaction for He-like and Li-like Multiply Charged Ions

Research output: Contribution to journalArticlepeer-review

Abstract

Exact quantum-electrodynamic calculations of the interelectron interaction corrections are performed for the 1s1/22s1/2 1S0, 1s1/22p1/2 3P 0, and 1s1/22s1/2 3S1 configurations in He-like ions and for the (1s1/2)22s 1/2 and (1s1/2)22p1/2 configurations in Li-like ions for all charges of nuclei 10 ≤ Z ≤ 92. The calculations are performed in the Coulomb calibration. The Coulomb-Coulomb and the Coulomb-Breit parts are calculated exactly, and the Breit-Breit part of the correction is calculated by neglecting the retardation. The calculations are the most exact of those available by now.
