Nuclear Raman Scattering of 10.38-MeV Photons byU238,Th232, andBi209

Abstract
We have measured the differential cross sections for the elastic scattering of 10.83-MeV photons by U, Th, and Bi targets and for inelastic scattering to the first excited states of the residual nuclei over a range of scattering angles. The inelastic scattering is found to be significantly weaker than predicted by currently accepted models of the giant dipole resonance.
