γ(d,n)preaction with polarized and unpolarized gamma rays

Abstract

The asymmetry function for the $\gamma \mathrm{}(d,n)p$ reaction is calculated for the Paris and supersoft core potentials for gamma-ray energies, $E_{\gamma }$, extending from 20 to 150 MeV, at center of mass angles 45°, 90°, and 135°. The relative photoneutron yield at $E_{\gamma }=20\mathrm{}$ MeV is also calculated. In addition, the differential cross section, total cross section, and polarization of the outgoing protons are reported. The Paris potential gives good agreement with the experimental data for the differential and total cross sections. However, the discrepancy at 0° still remains. It is found that the asymmetry function cannot be used to distinguish between the various nucleon-nucleon potentials.
