✦ Synopsis

Gamma-rays, charged particles and evaporation residue products from lso+1°°Mo collisions at E(lso)=125 to 217 MeV have been measured in order to understand better the width evolution of the GDR in hot nuclei. Detailed angular distributions of all reaction products are used to determine important preequilibrium and bremsstrahlung effects and the giant-dipole parameters as a function of temperature. Results show the GDR width increasing with final-state temperature up to T=2.5 MeV, in contrast with previous works which argue for a saturation of the width in this energy range.
