Abstract:
We consider the role of the Coulomb boundary conditions (CBC) for the radiative electron capture (REC) in fast nonrelativistic collisions of light atomic particles. To do this we adapted a formalism in which the REC is viewed as collision stimulated transitions between electron states dressed by the radiation field. The consideration suggests that, in sharp contrast to the case with the non-radiative electron capture, the inclusion of the CBC does not substantially change the calculated total cross section for the radiative capture. However, the CBC can noticeably influence the calculated energy spectrum of the emitted photons.
