Abstract
Energy shifts arising from two photo exchange graphs are calculated for N=2 triplet states of heliumlike ions and tabulated for the range of nuclear charges Z = 30-92. The results are compared with second-order many-body perturbation theory (MBPT), and the differences identified as QED effects associated with retardation and negative energy states not included in MBPT.Citation
