Reaction dynamics with exotic nuclei

Isospin effects in nuclear fragmentation

Neck fragmentation reaction mechanism

Searching for signatures of a liquid–gas transition has motivated great efforts in the study of heavy-ion collisions at intermediate energies in the last few years. This review describes the main contributions obtained so far for such a search using data from the INDRA array.

Dynamics and thermodynamics of the liquid-gas phase transition in hot nuclei studied with the INDRA array

Heavy-ion collisions have been widely used in the last decade to constrain the parameterizations of the symmetry energy term of the 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 $ \rho_{0}=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.
