The reactions 78Kr + 40Ca and 86Kr + 48Ca at 10 A MeV, have been studied in Catania at LNS with the 4π multi detector CHIMERA.
For these systems, we have already analyzed the fusion-evaporation and fission-like processes, [1,2,3]. In this work we present a new study concerning the break-up of the Projectile-Like (PLF) into two fragments, following more violent deep-inelastic collisions.
A selection method has been developed, in order to discriminate PLF break up events from those due to other mechanisms 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 the presence of some dynamical effects.
As the isospin is expected to play a crucial role in the onset of this process; a comparison between the neutron-rich 86Kr +48 Ca and neutron-poor 78Kr +40 Ca systems will be presented.
