Abstract
The study of the elastic np → np(pn) scattering was carried out at the momenta of incident quasimonochromatic neutrons P 0 = 1.43, 2.23 and 5.20 GeV/c. The differential cross sections of the processes of elastic np scattering, both without (cos Φ* p < 0) and with charge exchange (cos Φ* p >0) of nucleons, are analyzed. The results are compared with the data of other experiments. The suggested pole model takes into account exchange by π meson, ρ meson, and includes the peripheral exchange mechanism. This model permits one to get a good description of the data of elastic np scattering at the energy region 1–10 GeV.
