Abstract

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