Description
The γ decay of the giant dipole resonance (GDR) in the 132Ce compound nucleus with temperature up to ≅4 MeV has been measured, using the reaction 64Ni+68Zn at Ebeam=300, 400, and 500 MeV. The γ and charged particles measured in coincidence with recoils are consistent with a fully equilibrated compound nucleus emission. The GDR width, obtained with the statistical model analysis, is found to increase almost linearly with temperature. This increase is rather well reproduced within a model including thermal shape fluctuations and the lifetime of the compound nucleus
