Relativistic corrections of order mα6: singular operators and regularization
Abstract
The finite operators are derived for the nonrecoil (leading order in the (m/M) expansion) relativistic corrections in hydrogen-like atoms and ions at orders mα6 in the two- and three-body formalism beyond the adiabatic approximation. Singular operators that appear in the derivation are analysed, and various regularization methods are discussed.
