Collisions induced by Be9,10,11 on a Zn64 target at the same c.m. energy were studied. For the first time, strong effects of the Be11 halo structure on elastic-scattering and reaction mechanisms at energies near the Coulomb barrier are evidenced experimentally. The elastic-scattering cross section of the Be11 halo nucleus shows unusual behavior in the Coulomb-nuclear interference peak angular region. The extracted total-reaction cross section for the Be11 collision is more than double the ones measured in the collisions induced by Be9,10. It is shown that such a strong enhancement of the total-reaction cross section with Be11 is due to transfer and breakup processes. © 2010 The American Physical Society.
