Abstract
The excitation of the giant dipole resonance induced by fusion reaction is studied with N/Z asymmetry in the entrance channel. The time dependent Hart ree-Fock solution exhibits a strong dipole vibration which can be associate d with a giant vibration along the main axis of the deformed compound nucle us. This dipole motion appears to be nonlinearly coupled to the shape oscil lation, leading to a strong modulation of its frequency. These phenomena ca n be detected in the gamma-ray emission from hot compound nuclei.
