Abstract
The cross section for the photodisintegration reaction has been calculated for photon energies from threshold ( MeV) up to MeV utilizing dispersion theory methods. In this energy region, the dominant contribution to the transition amplitude results from diagrams characterized by the virtual breakups , , and rescattering corrections. In the calculation, the coupling constant for the , vertex is obtained from an analysis of quasielastic cross sections for . The coupling constant is determined from an analysis of quasielastic cross section for . The predicted cross section agrees both in shape and magnitude with the experimental results. The calculated cross section integrated up to the - threshold is 13.0 MeV mb, while experimentally it is found to be 12.4-14.6 MeV mb.
