Deuteron Photodisintegration in the Medium Energy Range

The photodisintegration of the deuteron is calculated for the two gamma -ray energies in the laboratory of 52.3 and 77.3 Mev, which corresponds to nucleon-nucleon scattering in the laboratory of 100 Mev and 150 Mev. For the ground state the Hulthen wave function with 4% D-state probability is used. The final state is described by the Signell-Marshak phase shifts. The coupling of the scattered waves is taken into account and the retardation effects and all dipole and quadrupole transitions are included. For unpolarized gamma rays the total cross section and the angular distribution are calculated. A comparison with the experiments is made. (auth)
