Abstract

The structure of C15, with an s1/2 neutron weakly bound to a closed-neutron shell nucleus C14, makes it a prime candidate for a one-neutron halo nucleus. We have for the first time studied the cross section for the fusion-fission reaction C15+Th232 at energies in the vicinity of the Coulomb barrier and compared it to the yield of the neighboring C14+Th232 system measured in the same experiment. At sub-barrier energies, an enhancement of the fusion yield by factors of 2-5 was observed for C15, while the cross sections for C14 match the trends measured for C12,13. © 2011 American Physical Society.
