STATISTICAL AND DYNAMICAL ASPECTS IN THE DECAY OF HOT NEUTRON-RICH NUCLEI Conference Paper uri icon

abstract

  • A signal of isospin-asymmetric phase transition in the evolution of chemical potential is observed in hot quasi-projectiles produced in the reactions 40,48 Ca + 27 Al confirming an analogous observation in the lighter quasi-projectiles observed in the reaction 28 Si + 112,124 Sn .1 With increasing mass, the properties of hot quasi-projectiles become increasingly influenced by secondary emission. Thermodynamical observables exhibit no sensitivity to a different number of missing neutrons in the two reactions 40,48 Ca + 27 Al and provide a signal of dynamical emission of neutrons, which can be related to a very neutron-rich low-density region (neck) between the projectile and target.
