Dynamical dipole mode in heavy-ion fusion reactions

Abstract The dynamical dipole mode, excited in charge asymmetric heavy-ion collisions, was investigated in the mass region of the 192 Pb compound nucleus, formed by using the 40,48 Ca + 152,144 Sm reactions at ∼11 MeV/nucleon. Preliminary results of this measurement, concerning both fusion-evaporation and fission events are presented. As a fast cooling mechanism on the fusion path, the dynamical dipole mode could be useful for the synthesis of super heavy elements through “hot” fusion reactions.
