Structure effects in collisions induced by halo and weakly bound nuclei around the Coulomb barrier

In this contribution, results concerning different reaction channels for the collisions induced by the three Be isotopes, (9,10,11)Be, on a (64)Zn target at energies around the Coulomb barrier will be presented. The experiments with the radioactive (10,11)Be beams were performed at REX-ISOLDE (CERN) whereas the experiment with the stable weakly bound (9)Be beam was performed at LNS Catania. Elastic scattering angular distributions have been measured for the three systems (9,10,11)Be + (64)Zn at the same center of mass energy. The angular distributions were analyzed with optical potentials and reaction cross sections were obtained from optical model calculations, performed with the code PTOLEMY. For the (11)Be + (64)Zn reaction, the break-up angular distribution was also measured.
