Title: Fusion of Radioactive 132Sn with 64Ni

Abstract

Sub-barrier fusion of 132Sn and 64Ni was measured with an improved apparatus. The new measurement suggests a cross section at least an order of magnitude smaller than 1 mb for our previous measurement at the lowest energy.

  • Evaporation residue and fission cross sections of radioactive {sup 132}Sn on {sup 64}Ni 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 {sup 132}Sn+{sup 64}Ni with respect to stable Sn+{sup 64}Ni. A systematic comparison of evaporation residue cross sections for the fusion of even {sup 112-124}Sn and {sup 132}Sn with {sup 64}Nimore » is presented.« less
  • Sub-barrier fusion of {sup 132}Sn and {sup 64}Ni was measured at E{sub beam}=465 MeV with an improved apparatus. The result of this new measurement is well reproduced by a coupled-channel calculation and a density-constrained time-dependent Hartree-Fock calculation. The previously measured cross section at E{sub beam}=453 MeV was reanalyzed. Only an upper limit of the cross section was obtained.
