Photodisintegration of the deuteron employing a supersoft core potential

Abstract

Employing the supersoft core potentials of deTourreil and Sprung, the differential cross section and polarization of the outgoing protons in the photodisintegration of the deuteron have been investigated for laboratory gamma-ray energies ranging from 10 to 150 MeV. The supersoft core potentials are found to give an appreciable decrease in the total cross section for the higher gamma-ray energies than when the Hamada-Johnston potential is used. These reductions in total cross section at higher energies are comparable with the increase obtained on including the effects of isobar configurations and meson exchange currents. The proton polarization is noticeably affected in $0°<{\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}<60\mathrm{}°$ at $E_{\gamma }^{\mathrm{lab}}=150\mathrm{}$ MeV.
