DEUTERON PHOTODISINTEGRATION UP TO 200 MEV .2. COMPARISON WITH EXPERIMENTAL-DATA

We use the model of deuteron photodisintegration presented in the previous paper to calculate the reaction observables and to compare theory and experiment up to 200 MeV lab photon energy. We describe how the parameters which control the 1piE, DELTA and 1rhoE contributions are fixed by means of a best fit to selected experimental data. We show that the data on the forward cross section cannot be fitted using the parametrised Paris and Moscow potentials. Using one of the versions of the Bonn coordinate-space potential, we obtain a rather satisfactory global fit to the whole body of data up to 200 MeV. The result is a conceptually simple picture of the reaction in this energy range, in which the calculated observables are completely dominated by the impulse approximation, 1piE in leading order and the contributions of DELTA and 1rhoE to the M(1) amplitudes with a singlet final state.
