Isospin Dependence of Incomplete Fusion Reactions at 25 MeV=Nucleon

Abstract : 40Ca þ 40;48Ca; 46Ti reactions at 25 MeV=nucleon have been studied using the 4 CHIMERA detector. An isospin effect on the competition between fusionlike and binarylike reaction mechanisms has been observed. The probability of producing a heavy residue is lower in the case of N Z colliding systems as compared to the case of reactions induced on the neutron rich 48Ca target. Predictions based on constrained molecular dynamics II calculations show that the competition between fusionlike and binary reactions in the selected centrality bins can constrain the parametrization of the symmetry energy and its density dependence in the nuclear equation of state.
