The gamma-decay of the GDR in the Ce-132 compound nuclei produced by the reaction Ni-64+Zn-68 at E-beam = 300 MeV, 400 MeV, 500 MeV (E* of 100 MeV, 150 MeV and 200 MeV) has been. measured. We have detected heavy recoil nuclei, light charged particles and gamma-rays. The data obtained with the symmetric reaction Ni-64+Zn-68 indicate emission from a fully equilibrated compound nucleus as deduced from the analysis of charged particle spectra. The GDR parameters are found to be consistent with the predictions of the thermal fluctuation model.
