Deuteron-proton backward elastic scattering at GeV energies

Deuteron-proton elastic scattering is considered at the energies from 880 MeV to 2 GeV at the scattering angles $θ^*\ge 140^\circ$. 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.

Study of Deuteron-Proton and Deuteron-Deuteron Collisions at Intermediate Energies

The $dp\to dp$ and $dd\to ^3He n$ reactions are considered in the energy range from few hundred MeV up to 1 GeV. The approach is based on the multiple-scattering theory, where the few-body collisions are presented through two-body ones. The high-energy nucleon-nucleon interactions are described by t-matrix, which is parameterized in accordance with the modern phase-shift analysis data. The special attention is given to investigation of the rescattering effects in these reactions. The theoretical predictions are obtained for the differential cross sections, vector and tensor analyzing powers. All results are presented in comparison with the existing experimental data.
