N2 - The corrections in the QED two-body problem are calculated in perturbation theory for the non-relativistic Schrödinger 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(l|γ)|n3.
