Abstract

The energy dependence phase shift of proton elastic scattering by ³He and T were investigated. The Feschbach unified theory of nuclear reactions was used. The threshold phenomenon ideas were developed on the basis of Feschbach theory. The phase shifts were obtained in the form analytical energetic function with taking into consideration 2- and multiple particle thresholds of reactions as well as compound nuclear levels at A=4. Differential elastic scattering cross section of p+³He was described theoretically in interval 2-11 MeV and in interval 2-4.6 MeV for p+T reaction. The theoretical parameters were obtained. The binary (from energy and scattering angles) differential cross section tables were produced.

Keywords
