Charge transfer in proton-hydrogen collisions by the Faddeev approach. II

A tractable form of the Faddeev equations as used by Chaudhuri et al. has been applied to the proton-hydrogen collision problem, retaining $1s$ and $2s$ states of the hydrogen atom in the expansion. To judge the effect of the proton interaction on the capture cross sections, calculations have been carried out with and without the inclusion of this interaction. The results for the $1s-2s$ capture and excitation cross sections are presented together with the elastic and ground-state capture cross sections. The present results have been compared with experimental findings and other theoretical results.
