摘要：

We have compared the fragment anisotropies of B-11 + Np-237 and O-16 + Th-232 which both populate the same fissioning system Cf-248. The data clearly show the evidence of the entrance-channel dependence of fission-fragment anisotropies. A new version of the preequilibrium fission model is put forward. In the framework of this model, the discrepancy between the experimental mean-square angular momentum [J(2)](exp.) and the prediction of the coupled-channels model, [J(2)](theory) is reasonably removed.
