Deuteron photodisintegration and p-wave phase shifts in the medium energy range

Abstract

The angular distribution and the parameter of the polarization of nucleons produced in deuteron photodisintegration are calculated for different phase shift sets which fit n-p scattering data corresponding to 40 MeV, 100 MeV and 150 MeV in the laboratory system. It is found that all the sets which are characterized by positive 3P 0 and negative 3P 1 phase shifts give similar results for the angular distribution. A small polarization results from sets with a large 3P 0 phase shift. For all of the sets which are characterized by a negative 3P 0 and a positive 3P 1 phase shift we obtain angular distributions which are outside the experimental errors, if one assumes that the D-state probability of the ground state is not extremely large.
