Description
Heavy-ion induced reactions offer unique opportunities to probe nuclear properties far from the ground state. The isospin flow during heavy-ion collisions is a subject of current investigation due to its link with the nuclear symmetry energy Esym which is only partly known far from stability and ground-state conditions. More specifically at incident energies between 10 and 100 MeV/A it is possible to investigate the thermal and mechanical properties of asymmetric nuclear matter. Also, they are of paramount importance in the astrophysical context for the description of the core-collapse of supernovae, as well as the formation and static properties of proto-neutron stars. The FAZIA program is aimed at investigating the evolution of isospin (i.e. the N/Z ratio) effects in heavy-ion collisions for excited (medium-light) quasi-projectiles (QP) formed in semi-peripheral collisions at Fermi energies. QP isospin observables (e.g. isobaric ratios, mass fragment distributions, N/Z of QP) are calculated from the data obtained for the study of isospin effects. The experiment is based on the excellent isotopic separation capability of the FAZIA detector telescopes (Si-Si-CsI(Tl)), permitted by the combined use of the $\Delta$E-E and PSA techniques and of fast digital electronics. In this contribution, I will report on the first results of the FAZIA-PRE experiment performed at LNS (Catania) with 6 FAZIA blocks, aiming at understanding the effects of pre-equilibrium neutron emission on relevant observables. I will focus on 48Ca+27Al reactions at 25 and 40 MeV/A.
