Abstract
The charge-exchange amplitude for the proton-hydrogen collision in the energy range 25-800 keV is calculated in the distorted-coupling Born approximation. The analysis is based on a reduced form of coupled equations of the Faddeev-Watson type, which was derived previously for the general manyparticle scattering. The effective distortion potentials which appear in these equations are determined by minimization of the coupling between the elastic and inelastic excitation channels. The result provides a mathematical basis with which various previous calculations can be compared. The present study strongly supports the applicability and effectiveness of the reduced-matrix equations in treating the rearrangement processes.
