Abstract
The halo structure is expected to influence the reaction mechanisms in nuclear collisions. The aim of the experiment discussed in the present paper is to compare the fusion excitation functions for the systems 6He + 64Zn and 4He + 64Zn, in order to investigate the effects of the 6He two-neutron halo structure on the fusion reaction mechanism at energies around the Coulomb barrier. In particular, new fusion cross-sections for the 4He + 64Zn systems at sub-barrier energies were measured to cover the same energy region of our previous measurements for 6He + 64Zn. The fusion cross-section was measured by using an activation technique. We have observed an enhancement of the fusion cross-section in the reaction induced by 6He when compared to the one induced by 4He on the same 64Zn target.
