Abstract
Nuclear reactions between medium-mass nuclei at low bombarding energy are characterized by the competition between binary and evaporation processes in the compound nucleus decay. A study of the influence of the neutron richness of the entrance channel on the decay paths of the compound nuclei formed in the 78Kr + 40Ca and 86Kr + 48Ca at 10MeV/A is presented. The experiment has been performed at Laboratori Nazionali del Sud by using the CHIMERA 4π multidetector for charged particles. The kinematical characteristics of the two reactions support the conclusion of a production of the IMFs via long-lived system and the global features suggest a different competition among the various reaction channels. The cross sections of the mechanisms responsible for the fragments production have been extracted. Besides the results relative to the n-poor system are compared to those obtained at GANIL, performed at 5.5AMeV, in order to study the energy influence on the mechanisms.
