Abstract：
We have succeeded in isolating the complete fusion-fission from transfer-induced fission in terms of the fragment folding angle distribution technique, and measured the complete fusion-fission cross sections and fragment angular distributions for the ¹⁶O+ ²³²Th system in the center-of-mass energies between 72.61 and 80.11 MeV. The observed fission excitation function is in quite good agreement with the expectation of the coupled-channels model. However, the measured angular distributions are more anisotropic than the predictions of both the saddle-point model and scission-point model.
