Differential Cross Section of DP-Elastic Scattering at Intermediate Energies

TL;DR

This paper investigates deuteron-proton elastic scattering at intermediate energies using a multiple scattering formalism, incorporating off-shell effects, and compares theoretical differential cross sections with experimental data at four energies.

Contribution

It introduces a detailed theoretical calculation of deuteron-proton elastic scattering including off-shell effects using the Love and Franey parameterization.

Findings

Theoretical differential cross sections agree with experimental data at studied energies.

Off-shell effects significantly influence the scattering calculations.

Multiple scattering contributions are essential for accurate modeling.

Abstract

The deuteron-proton elastic scattering is studied in the multiple scattering expansion formalism. The contributions of the one-nucleon-exchange, single- and double scattering are taken into account. The Love and Franey parameterization of the nucleon-nucleon $t$-matrix is used, that gives an opportunity to include the off-energy-shell effects into calculations. Differential cross sections are considered at four energies, $T_d=390, 500, 880, 1200$ MeV. The obtained results are compared with the experimental data.
