Fusion of short-lived 132Sn with 64Ni

2007
Evaporation residue and fission cross sections of radioactive $$^{132}$$Sn on $$^{64}$$Ni were measured near the Coulomb barrier. A large sub-barrier 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, no extra fusion enhancement is observed in $$^{132}$$Sn+$$^{64}$$Ni with respect to stable Sn+$$^{64}$$Ni. A systematic comparison of evaporation residue cross sections for the fusion of even $$^{112-124}$$Sn and $$^{132}$$Sn with $$^{64}$$Ni is presented.
