Abstract
High precision numerical calculations of atomic first-order self-energy shift are presented whose divergences are eliminated by a partial wave expansion of the mass renormalization operator. The method is novel because the usual parametric or dimensional regularization of the electromagnetic interaction is not required. A complete self-energy calculation for Hg79+ is examined in detail.Keywords
