Photon Scattering from Protons and Deuterons

Abstract

The scattering of dipole photons of 100 to 200 Mev from protons and deuterons is calculated by means of dispersion relations, experimental data on photopion production from nucleons, and several reasonable approximations. A previous calculation by the author using this model is modified by the use of an additional dispersion relation derived by Mathews. The differential cross sections resulting from this modification are smaller than the previously calculated cross sections for scattering angles in the backward direction. Comparison of the photon-deuteron calculations with the results of future experiments will yield information concerning the photon-neutron scattering amplitude.
