Statistical and dynamical aspects in the decay of hot neutron-rich nuclei Academic Article uri icon

abstract

  • A signal of isospin-asymmetric phase transition in the evolution of the chemical potential was observed in hot quasi-projectiles produced in the reactions Ca40,48+27Al confirming an analogous observation in the lighter quasi-projectiles observed in the reaction Si28+Sn112,124 (Veselsky et al., 2004 [1]). With increasing mass, the properties of hot quasi-projectiles become increasingly influenced by secondary emission. Thermodynamical observables exhibit no sensitivity to the different number of missing (undetected) neutrons in the two reactions Ca40,48+Al27 and provide a signal of dynamical emission of neutrons, which can be related to the formation and disintegration (rupture) of a very neutron-rich low-density region (neck) between the projectile and target. 2010 Elsevier B.V.
