Abstract
Various aspects observed in the reactions 40Ca+40,48 Ca,46Ti at E =25 MeV / nucleon , studied by means of the CHIMERA detector, will be discussed. An isospin effect on the competition between heavy residue production and binary-like channels has been observed in incomplete fusion events. From the thermodynamical point of view, kinetic energy spectra of protons emitted in fusion-evaporation events were fitted with two maxwellian functions. Despite of the different neutron richness of the populated sources, the average temperatures obtained for the quasi-fused systems are similar ( T ≃5.2 MeV ). We also performed a preliminary reconstruction of the excitation energy reached by quasi-fusion sources populated in the studied reactions.
