Retardation effects in radiative electron capture

Three-particle radiative electron-capture cross sections with retardation are calculated within the nonrelativistic treatment. The formalism is carried out in the laboratory frame. It is found that the center of mass genuinely radiates, and it plays an important role in restoring the backward-forwar...
