New fusion data for the He-4+Zn-64 system at sub-barrier energies are measured to cover the same energy region of previous measurements for He-6+Zn-64. Aim of the experiment was to compare the fusion excitation functions for the two system to investigate on the effects of the He-6 neutron-halo structure on the fusion reaction mechanism at energies around the Coulomb barrier. The fusion cross section was measured by using an activation technique. Comparing the two systems, we observe an enhancement of the fusion cross section in the reaction induced by He-6, at and below the Coulomb barrier.
