Abstract
124Sn+64Ni and 112Sn+58Ni reactions at 35 A MeV incident energy were studied by using the 688 Si–CsI telescopes of the forward part (1°⩽θlab⩽30°) of CHIMERA multi-detector. The most central part, 1% of the total measured cross section was selected by means of a multidimensional analysis of the experimental observables. The detected isotopes of light fragments (3⩽Z⩽8) provided information on breakup temperatures of the emitting sources. The space–time structure of these sources was deduced from fragment correlations. An odd–even effect in the fragment production, enhanced by the isospin of the entrance channel, was observed. Freeze-out unbound neutron-to-proton relative densities for both studied reactions have been deduced, indicating for a possible isospin distillation mechanism related to a phenomenon of the liquid–gas phase transition in asymmetric systems.
