“…This ratio depends slightly upon the emission angle and the Z of the PLF. The strong dependence of the PLF isotopic distributions from the projectile A/Z ratio, a sort of "memory effect", has been evidenced in [18]. The standard deviation of the isotopic distributions indicated by the vertical bars in Fig.…”

Results on projectile fragment-fragment coincidences in the forward direction and for the reaction 40 Ar+ 27 Al at 44 A.MeV are presented and compared with the predictions of two different entrance channel models, a two-body and a three-body mechanism both followed by a binary multisequential decay including fission. This analysis shows that many features of the projectile decay products are well accounted for by the binary multisequential decay model. However the results depend critically upon the initial masses and excitation energies of the primary projectile fragments. In this respect, the three-body approach underestimates the excitation energy imparted to the primary fragments whereas the two-body scenario overestimates it. The present data put strong constraints on the initial excitation energy imparted to the primary fragments which appears to be intermediate between the predictions of the two models.

“…A characteristic odd-even effect in charge (mass) distribution is given by a staggering behavior of the charge (mass) production cross section of the detected fragments. A staggering effect has been observed in heavy ion collisions in a broad range of incident energies (from 5 to 1000 A MeV) and different reaction mechanisms [112,113,114,115,116]. In fact, staggering is found in low energy heavy ions physics, in particular in the compound nucleus and its decaying modes of excited residues [111].…”

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.
