Abstract

Signals from Double Dipole Giant Resonances (DGDR) in hot nuclei have been searched in a gamma-gamma coincidence experiment using the HECTOR array at the Laboratori Nazionali di Legnaro. The experimental single gamma-ray spectrum and the projection of the gamma-gamma matrix have been compared with a standard Monte Carlo Statistical Model code including only the single CDR excitation. These calculations have been used as background to determine the extra-yield associated with the DGDR de-excitation. Results have been compared with a previous experiment confirming the presence of the DGDR excitation in fusion-evaporation reactions.
