“…The neutron to proton ratio, N/Z, influences many properties of the particle decay chain of the de-excitation process, as the level density [125], the staggering in the residue cross-sections, the fission barriers that are sensitive to the symmetry energy component [126] of the semi-empirical nuclear mass formula [127]. Recently these aspects have been studied by the INDRA collaboration in the reactions 78,82 Kr + 40 Ca at 5.5 A MeV at GANIL [111] and more recently by the CHIMERA-ISODEC collaboration at LNS in the study of the reactions 78,86 Kr + 40,48 Ca at 10 A MeV [25].…”

Abstract. Heavy ion collisions have been widely used in the last decade to constraint the parameterizations of the symmetry energy term of nuclear equation of state (EOS) for asymmetric nuclear matter as a function of baryonic density. In the Fermi energy domain one is faced with variations of the density within a narrow range of values around the saturation density ρ0=0.16 fm −3 down towards sub-saturation densities. The experimental observables which are sensitive to the symmetry energy are constructed starting from the detected light particles, clusters and heavy fragments that, in heavy ion collisions, are generally produced by different emission mechanisms at different stages and time scales of the reaction. In this review the effects of dynamics and thermodynamics on the symmetry energy in nuclear reactions are discussed and characterized using an overview of the data taken so far with the CHIMERA multi-detector array.
