Abstract

The structure of ${}^{15}C$ , with an $s_{1 / 2}$ neutron weakly bound to a closed-neutron shell nucleus ${}^{14}C$ , 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 ${}^{15}C + {}^{232}{Th}$ at energies in the vicinity of the Coulomb barrier and compared it to the yield of the neighboring ${}^{14}C + {}^{232}{Th}$ system measured in the same experiment. At sub-barrier energies, an enhancement of the fusion yield by factors of 2–5 was observed for ${}^{15}C$ , while the cross sections for ${}^{14}C$ match the trends measured for ${}^{12, 13}C$ .
