Relativistic recoil corrections of order \boldmath $m (Z α)^{6} (m / M)$ : Hydrogen-like atom and hydrogen molecular ion

arXiv:2506.03644

Abstract

The finite operators are derived for the recoil $m α^{6} (m / M)$ order relativistic corrections (to spin-averaged energy levels) in hydrogen-like atoms and ions in the two- and three-body formalism beyond the adiabatic approximation. Results are presented in a form suitable for numerical evaluation.
