摘要：

Fission following the fusion of He-6 with a Bi-209 target has been studied near the Coulomb barrier, at excitation energies of 32 and 34 MeV in the compound system. These new experimental data are in disagreement with previous work which reported an anomalously large fusion-fission yield, when compared with He-4-induced fission of Bi-209 at similar excitation energies. In fact, the He-6-induced fusion-fission yield appears to be smaller than that for He-4, in qualitative agreement with conventional statistical model calculations.
