The dynamical dipole mode was investigated in the mass region of the 192Pb compound nucleus, by using the 40Ca + 152Sm and 48Ca +144Sm reactions at Elab = 11 and 10.1 MeV/nucleon, respectively.

Abstract

The dynamical dipole mode was investigated in the mass region of the 192Pb compound nucleus, by using 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. Our results show that the dynamical dipole mode survives in reactions involving heavier nuclei than those studied previously. However, its yield is lower than that expected within BNV calculations.
