Fusion reactions with the one-neutron halo nucleus 15C

We have for the first time studied the fusion-fission excitation functions for the systems 14,15 C + 232 Th at energies in the vicinity of the Coulomb barrier. At energies below the barrier, the fusion cross section of the halo nucleus 15 C showed an enhancement by a factor of 2-5, while the fusion cross section for 14 C shows a similar trend to that of 12,13 C.
