Isotope analysis in central heavy ion collisions at intermediate energies

. Symmetry energy is a key quantity in the study of the equation of state of asymmetric nuclear matter. Heavy ion collisions at low and intermediate energies, performed at Laboratori Nazionali di Legnaro and Laboratori Nazionali del Sud, can be used to extract information on the symmetry energy coefficient C sym , which is currently poorly known but relevant both for astrophysics and for deeper knowledge of the structure of exotic nuclei.
