Recoil corrections in the hydrogen isoelectronic sequence
G. S. Adkins, J. Sapirstein
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 particl…

Analytic evaluation of the amplitudes for orthopositronium decay to three photons to one-loop order
Gregory S. Adkins
The matrix element for the decay of orthopositronium to three photons can be expressed in terms of three independent amplitudes. We describe the analytic evaluation of these amplit…
