Abstract

The existence of the dynamical dipole mode in the ¹⁹²Pb composite system was investigated through the study of its prompt γ decay employing the ⁴⁰Ca + ¹⁵²Sm and ⁴⁸Ca + ¹⁴⁴Sm reactions at E_lab =11 and 10.1 MeV/u, respectively. The γ-rays and light charged particles were detected in coincidence with evaporation residues and ﬁssion fragments. First 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 γ radiation could be of interest for the synthesis of super-heavy elements through ”hot” fusion reactions. Furthermore, by using radioactive beams and the prompt γ radiation as a probe we could get information on the symmetry energy at sub-saturation densities.
