An approximate form of the Faddeev equations was applied to the charge- transfer process in proton--hydrogen collisions. The effect of coupling with the direct channel was taken into account. This formalism satisfies the unitarity condition below the breakup threshold. Results for the ground-state capture cross section were obtained with and without the inclusion of the effect of proton-proton interactions. The experimental findings for the capture cross section in the energy range 1 to 50 keV lie in between the two sets of results. At high incident energies the results with and without the proton--proton irteraction have approached the JacksonSchiff and Brinkman--Kramers cross sections respectively. The differertial cross sections for the capture in the forward direction were compared with the corresponding results of other theorists. Results for the elastic cross section were also obtained.
