Elastic and Raman scattering of 9.0 and 11.4 MeV photons from Au, Dy, and In

Abstract

Monoenergetic photons between 8.8 and 11.4 MeV were scattered elastically and inelastically (Raman) from natural targets of Au, Dy and In. 15 new crosss sections were measured. Evidence is presented for a slight deformation in the 197 Au nucleus, generally believed to be spherical. It is predicted, on the basis of these measurements, that the Giant Dipole Resonance of Dy is very similar to that of 160 Gd. A narrow isolated resonance at 9.0 MeV is observed in In.
