Abstract
A rapid increase in the emission of prescission giant dipole resonance (GDR) γ-rays with bombarding energy is observed in excited Th and Cf nuclei formed in the reactions 16O+ 208Pb and 32S+ natW, 208Pb. This increase begins around E exc = 40 MeV for the 16O+ 208Pb reaction and E exc = 70 MeV for the 32S-induced reactions. The excess γ-ray yield above these thresholds cannot be described within the standard statistical model. Statistical model calculations which include a temperature dependent nuclear dissipation are able to reproduce simultaneously the observed GDR γ-ray spectra and recently measured evaporation residue cross sections.
