Abstract
The reactions Xe-124 + Zn-64 and Ni-64 at 35 A MeV beam incident energy (InKiIsSy, Inverse Kinematic Isobaric System) were studied at INFN-LNS with the 4 pi CHIMERA detector and compared to results of previous studied reactions Sn-124,Sn-112 + Ni-64,Ni-58. The Intermediate Mass Fragments (IMF) production probability and emission mechanism in the projectile-like fragments (PLF) fission were studied by using, as main observable, the angle between the center of mass velocity of the kinematical reconstructed PLF* respect to the relative velocity of the PLF* break-up fragments. We show that prompt-dynamical emission is enhanced by increasing the projectile and target Isospin content in the entrance channel. It is found that the dynamical emission increases, separately, at the increasing of the projectile and target isospin respectively. Experimental results are compared within the framework of the Constrained Molecular Dynamic code.File | Dimensione | Formato | |
