Abstract

The two-loop self-energy correction is evaluated to all orders in Zα for the ground-state Lamb shift of H-like ions with Z ≥ 20, where Z is the nuclear charge number and α is the fine structure constant. The results obtained are compared with analytical calculations performed within the Zα-expansion.
