Conference paper


A study of the spectral and angular distributions of the high energy γ rays emitted by the giant dipole resonance (GDR) in the compound nuclei 165,167Er and 110Sn at a variety of excitation energies (E* = 50–90 MeV) is presented. A comparison of the data with model predictions at the equilibrium deformation and with thermal fluctuations in the adiabatic limit is discussed. In general, the adiabatic calculations give a fair account of the data exception made for Sn at very high spins.
