Corrections of O(α6logα) in the two-body QED problem

Description
The corrections in the QED two-body problem are calculated in perturbation theory for the non-relativistic Schroedinger equation. Perturbation operators are derived by computing on-mass-shell Feynman diagrams in a non-covariant approach. For positronium, the calculated logarithmic corrections does not vanish only in n3S1 states and equals 5/24mα6log(1/α)/n3. (orig.)
