Recent measurements have been performed at the National Laboratory of Legnaro using mass-symmetric (400, 500 MeV Ni-64 + Zn-68) and mass-asymmetric (250 MeV O-16 + Sn-116) entrance channel reactions to form Ce-132 compound nucleus at different excitation energies (E*= 150, 200 and 200 MeV, respectively). The decay of the composite system has been followed studying the gamma-rays and Light Charged Particles (LCP) spectra emitted in coincidence with the Evaporation Residues (ER). In this way the emission mechanism of the LCP, depending on the mass-asymmetry at the entrance channel and on the projectile energy, and the results of the Full Width Half-Maximum (FWHM) of the Giant Dipole Resonance as a function of the nuclear temperature have been studied.

Abstract
Recent measurements have been performed at the National Laboratory of Legnaro using mass-symmetric (400, 500 MeV Ni-64 + Zn-68) and mass-asymmetric (250 MeV O-16 + Sn-116) entrance channel reactions to form Ce-132 compound nucleus at different excitation energies (E*= 150, 200 and 200 MeV, respectively). The decay of the composite system has been followed studying the gamma-rays and Light Charged Particles (LCP) spectra emitted in coincidence with the Evaporation Residues (ER). In this way the emission mechanism of the LCP, depending on the mass-asymmetry at the entrance channel and on the projectile energy, and the results of the Full Width Half-Maximum (FWHM) of the Giant Dipole Resonance as a function of the nuclear temperature have been studied.
