The reaction $^{6}\mathrm{He}+^{64}\mathrm{Zn}$ 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 $^{6}\mathrm{He}$ 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 $^{4}\mathrm{He}+^{64}\mathrm{Zn}$ was studied using the same technique. The data for the reaction $^{6}\mathrm{He}+^{64}\mathrm{Zn}$ 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 $^{4}\mathrm{He}+^{64}\mathrm{Zn}$ reaction.
