Abstract

High-energy rays have been measured in coincidence with heavy fragents in deeply inelastic reactions of Xe136+48Ti at 18.5 MeV/nucleon. The giant dipole resonance (GDR) strength function is deduced from an analysis of the photon spectra within the statistical model. The GDR width is studied as a function of the fragment excitation energy E*. A saturation at about =10 MeV is observed for E*/A1.0 MeV/nucleon.
