The prompt radiation originating from the dynamical dipole mode decay was investigated in the 192Pb composite system employing the 40Ca + 152Sm and 48Ca + 144Sm reactions at Elab=11 and 10.1 MeV/nucleon, respectively. The -ray energy spectra at various polar angles were obtained for fusion-evaporation and fission events by detecting the high energy rays with the MEDEA experimental apparatus in coincidence with evaporation residues and fission fragments. Preliminary results of this experiment show that the dynamical dipole mode survives in collisions involving heavier mass reaction partners than those studied previously. As a fast cooling mechanism on the fusion path, the prompt dipole radiation could be of interest for the synthesis of super-heavy elements through "hot" fusion reactions.

Abstract

The prompt radiation originating from the dynamical dipole mode decay was investigated in the 192Pb composite system employing the 40Ca + 152Sm and 48Ca + 144Sm reactions at Elab=11 and 10.1 MeV/nucleon, respectively. The -ray energy spectra at various polar angles were obtained for fusion-evaporation and fission events by detecting the high energy rays with the MEDEA experimental apparatus in coincidence with evaporation residues and fission fragments. Preliminary results of this experiment show that the dynamical dipole mode survives in collisions involving heavier mass reaction partners than those studied previously. As a fast cooling mechanism on the fusion path, the prompt dipole radiation could be of interest for the synthesis of super-heavy elements through "hot" fusion reactions.
