Аннотация:The process in which a fast passing proton captures an electron from a hydrogen atom and scatters at small angles is considered. In contrast to previous calculations within the peaking approximation the numerical calculations of the second Born as well as second Born-Faddeev diagrams are presented. The results of calculations are compared with the experimental data obtained at 2.8 and 5.0 MeV impact energy. It is shown that numerical second Born calculations give quite different results from that in the peaking approximation. In particular, the role of the pp interaction is rather noticeable. On the other hand, the second Born-Faddeev numerical calculations clearly demonstrate the important role of distortion of plane waves.
