摘要：
The gamma decay of the Giant Dipole Resonance (GDR) in Ce-132 nuclei has been measured using the reactions Ni-64 (E-lab = :300,400, 500 MeV) + Zn-68 and O-16 (E-lab = 130,250 MeV) + 116 Sn. The analysis of the data shows clearly that the GDR, width increases steadily with temperature at least up to 4 MeV of the temperature. The data can be well interpreted within the thermal shape fluctuation model.
