Abstract

Cross sections for elastic and inelastic scattering of monochromatic photons from Zr90 have been measured for excitations between 8.1 and 10.5 MeV. The observed inelastic cross sections i correspond to transitions to the 02+, 21+, 22+, and 23+ states. A simple theoretical description using the Brink-Axel hypothesis and estimates of the level density and of the total photon interaction cross section T gives predictions for the individual cross sections that are in very good agreement with data. The E1 strength corresponding to the inferred T amounts to about B(E1)0.5 e2 fm2 for the energy range under consideration.
