Abstract
The reactions 78Kr + 40Ca and 86Kr + 48Ca realized at 10AMeV, have been studied in Catania at LNS with the 4π multidetector CHIMERA. For these systems, we have already studied the fusion-evaporation and fission-like processes. Now we will present a study of the break-up of the Projectile-Like Fragment (PLF) into two fragments, following more violent deep-inelastic collision. A selection method has been developed, in order to discriminate PLF break-up from events due to other mechanisms, fusion-fission–like processes, which populate the same region of the phase-space. A preference for PLF aligned break-up, along the direction of the PLF-TLF separation axis with the light fragment emitted in the backward part, has been evidenced, suggesting dynamical-nonequilibrium effects. The isospin is expected to play a crucial role in the onset of this process; a comparison between the neutron-rich 86Kr + 48Ca system and neutron-poor 78Kr + 40Ca one will be presented.
