Abstract
Semi-central events of collisions 40;48Ca +40;48 Ca at 25 MeV/nucleon have beeninvestigated by means of the Chimera multi-detector array. We ¯nd that the competitionbetween evaporation residue and two or more fragment emission is regulated in a strong wayby the neutron to proton ratio of the total reaction system. Comparisons of experimental dataand Constrained Molecular Dynamics model calculations allow to obtain information about thebehavior of the symmetry energy of the nuclear Equation of State.| File | Dimensione | Formato | |
