Fusion of radioactive 132Sn with 64Ni

Evaporation residue and fission cross sections of radioactive Sn-132 on Ni-64 were measured near the Coulomb barrier. A large subbarrier fusion enhancement was observed. Coupled-channel calculations, including inelastic excitation of the projectile and target, and neutron transfer are in good agreement with the measured fusion excitation function. When the change in nuclear size and shift in barrier height are accounted for, there is no extra fusion enhancement in Sn-132+Ni-64 with respect to stable Sn+Ni-64. A systematic comparison of evaporation residue cross sections for the fusion of even Sn112-124 and Sn-132 with Ni-64 is presented.
