Reaction studies with low-energy weakly-bound beams at INFN-LNS

Abstract

The reaction dynamics of collisions involving halo or weakly bound nuclei, at energies around the Coulomb barrier, can be strongly affected by the structure of such nuclei. Very strong entrance channel effects have been observed on various reaction pocess such as, elastic scattering, fusion and direct reactions when comparing collision induced by the 6 He and 11 Be halo nuclei with the ones induced by their cores 4 He and 10 Be. Collisions induced by the stable weakly bound nuclei 6 Li, 7 Li show also some peculiarities in comparison to the ones induced by well bound nuclei; coupling with the break-up channel is in fact very important in reproducing low energy data. In this contribution an overview of our present understanding of the discussed topic will be given along with the discussion of some new preliminary results.
