Giant dipole resonance built on hot rotating nuclei produced during evaporation of light particlesfrom the $^{88}$Mo compound nucleus
High-energy giant dipole resonance (GDR) γ rays were measured following the decay of the hot, rotatingcompound nucleus of 88Mo, produced at excitation energies of 124 and 261 MeV. The reaction 48Ti+ 40Ca at 300and 600 MeV bombarding energies has been used. The data were analyzed using the statistica...
