Radiative electron capture in proton-hydrogen collision
The 1s-1s proton-hydrogen radiative electron capture is studied within the nonrelativistic semiclassical approximation. Several three-particle theoretical methods currently used in collision theory are applied. Double, single, and total cross sections are computed. The continuum distorted-wave metho...
