Abstract

The reaction He6+Zn64 was studied in order to investigate the effects of the projectile neutron-halo structure on the reaction mechanism at energies around the Coulomb barrier. Elastic scattering angular distributions, transfer∕breakup angular distributions, and fusion excitation functions have been measured. Due to the low-recoil energy of the evaporation residues and the low intensity of the He6 beam, the fusion cross section was measured by detecting off-line the atomic x-ray emission which follows the electron capture decay of the evaporation residues. For comparison the reaction He4+Zn64 was studied using the same technique. The data for the reaction He6+Zn64 show that the transfer and breakup mechanisms account for almost 80% of the total reaction cross section, moreover we do not observe an enhancement of the fusion cross section when compared with the He4+Zn64 reaction.
