Elastic Photon Scattering on the Deuteron in a Potential Model.
M. I. Levchuk and A. I. L'vov

Deuteron Compton scattering below pion photoproduction threshold is considered in the framework of the nonrelativistic diagrammatic approach. The nonrelativistic version of the Bonn one-boson exchange potential is used to generate the deuteron wave function and the NN-scattering amplitude. A complete set of gauge-invariant diagrams is taken into account. It is demonstrated how separate diagrams contribute to the low-energy limit of the amplitude. The model is used to extract the isospin-averaged dipole electromagnetic polarizabilities of the nucleon from the available data.
Key words: Compton scattering, electromagnetic polarizabilities, deuteron, neutron, meson-exchange currents, seagulls
