Scattering of Plane-Polarized Photons by the Giant Resonances of Nuclei

Abstract
The cross sections for the electric dipole scattering of plane-polarized photons are expressed in terms of the angular momentum transferred to the nucleus in the two-step scattering process. These scattering cross sections have been evaluated in the dynamic collective model for a number of vibrational nuclei at 15.1 MeV and for a number of deformed nuclei at 11.4 and 15.1 MeV. A sum rule is derived that relates the total scattering cross section for an odd-A nucleus to that of its even-even neighbor.
