Deuteron-proton backward elastic scattering at GeV energies

Abstract

Deuteron-proton elastic scattering is considered at the energies from 880 MeV to 2 GeV at the scattering angles ${\theta }^{\ast }\ge 140^{\circ }$. The multiple-scattering method is used to calculate the reaction amplitude. Four reaction mechanisms are taken into account: one-nucleon-exchange, single-scattering, and double-scattering with a nucleon and a delta-isobar in the intermediate state. The method allows calculating both unpolarized differential cross section and any polarization observables. All the results obtained are compared to the experimental data.
