【 摘 要 】

In this work we give evidence for the first time of the Dynamical Dipole mode in a heavy system in the A∼190 mass region, in both fusion-evaporation and fission events. The40,48Ca +152,144Sm reactions at Elab=11(10.1) MeV/nucleon were employed. Our results for evaporation and fission events (preliminary) show that the dynamical dipole mode survives in reactions involving heavier nuclei than those studied previously.
