摘要：
Recent advances concerning the study of the Giant Dipole Resonance in hot rotating nuclei are discussed. The gamma-decay of the GDR built on excited states as a function of nuclear temperature and angular momentum is reviewed for the two mass regions, A approximate to 110 and A approximate to 170, characterized by different nuclear shapes. The data show the different effects of temperature and angular momentum. A new generation of experiments has been undertaken in which particular decay cascades of the compound nucleus containing high-energy gamma-rays are selected. Two measurements of this type are presented. One was made to study of the GDR in Hg-194 and to test in detail the hypothesis of thermalization and the other aimed at searching the GDR in a superdeformed nucleus.
