摘要：

Contributions of one-loop ladder and crossed-ladder graphs to the ground-state energy of heliumlike ions are calculated in Furry representation QED. With the aid of a contour rotation, the graphs are evaluated to all orders in Zalpha in the range Z = 10-110. Particular attention is given to the relation of this work to recent many-body perturbation theory and configuration-interaction calculations.
