“…By increasing the degree of dissipation of the reaction, two sources of emission remain evident, indicating a clear persistency of the binary (PLF,TLF) character of the reaction. More complex methods, as principal component analysis PCA) [33] or sorting methods based on observables related to the momentum shape of the events are needed when small cross-sections in central collisions have to be selected (for example for characterization of multifragmentation source from a single fused source) [34,35].

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.

“…Odd-even staggering was observed also in light fragments produced by fragmentation or spallation at relativistic energies (see, e.g., [5][6][7][8]) and more recently even in heavy ion collisions at Fermi energies (15 E/A 50 MeV/nucleon) [9][10][11][12][13]. The study of odd-even effects has gained renewed interest from this last finding.…”

The odd-even staggering of the yield of final reaction products has been studied as a function of proton (Z) and neutron (N ) numbers for the collisions 84 Kr+ 112 Sn and 84 Kr+ 124 Sn at 35 MeV/nucleon, in a wide range of elements (up to Z ≈ 20). The experimental data show that staggering effects rapidly decrease with increasing size of the fragments. Moreover the staggering in N is definitely larger than the one in Z. Similar general features are qualitatively reproduced by the GEMINI code. Concerning the comparison of the two systems, the staggering in N is in general rather similar, being slightly larger only for the lightest fragments produced in the n-rich system. In contrast the staggering in Z, although smaller than that in N , is sizably larger for the n-poor system with respect to the n-rich one.

“…An enhanced production of even-Z fragments with respect to odd-Z ones has been observed for a long time in a variety of nuclear reactions (see [1][2][3][4][5][6] and references therein). The enhancement in the yield of even elements over the neighboring odd ones is usually of the order of few tens percent for the lightest elements and it rapidly decreases with increasing Z.…”

Odd-even staggering effects on charge distributions are investigated for fragments produced in semiperipheral and central collisions of 112 Sn + 58 Ni at 35 MeV/nucleon. For fragments with Z 16 one observes a clear overproduction of even charges, which decreases for heavier fragments. Staggering persists up to Z ∼ 30. The staggering appears to be substantially independent of the centrality of the collisions, suggesting that it is mainly related to the last few steps in the decay of hot nuclei.
