Recoil corrections in the hydrogen isoelectronic sequence
/ Authors
/ Abstract
A version of the Bethe-Salpeter equation appropriate for calculating recoil corrections in highly charged hydrogenlike ions is presented. The nucleus is treated as a scalar particle of charge Z, and the electron treated relativistically. The known recoil corrections of order m{sup 2}/M(Z{alpha}){sup 4} are derived in both this formalism and in NRQED.
