© Owned by the authors, published by EDP Sciences, 2011. The collision induced by the three Beryllium isotopes, 9,10,11 Be, on a 64 Zn target were investigated at E c.m. ? 1.4 the Coulomb barrier. The experiments with the radioactive 10,11 Be beams were performed at the Rex-Isolde facility at CERN. In the case of 9,10 Be, elastic scattering angular distributions were measured whereas, in the 11 Be case, the quasielastic scattering angular distribution was obtained. A strong damping of the quasielastic cross-section was observed in the 11 Be case, in the angular range around the Coulomb-nuclear interference peak. In this latter case a large total-reaction cross-section is found. Such a cross-section is more than a factor of two larger than the ones extracted in the reactions induced by the non-halo Beryllium isotopes. A large contribution to the total-reaction cross-section in the 11 Be case could be attributed to transfer and/or break-up events.
