Abstract: (APS)
The γ-ray spectrum in the giant dipole resonance (GDR) region associated with the reaction 40Ar+70Ge at 10 MeV/nucleon has been measured in coincidence with residues of the heavy composite systems whose excitation energy was E*=230 MeV. From the statistical-model analysis, it is deduced that the GDR strength is consistent with 100% of the energy-weighted sum rule, the energy is 16±1 MeV while the width is 13−2+1 MeV. This value is not very different from the one measured at E*=130 MeV, thus pointing to saturation effects in the damping of the GDR.- 27.60.+j
