Abstract：
It is verified experimentally that the heavy-ion-induced fusionfission reactions are entrance-channel mass asymmetry dependent.This dependence means that in some cases,the fused composite systems havenot forgot the history of it's formation.Based on the experimental observations,we have put forward a preequilibrium fission model.In framework of this model,we have successfully explained the anomalous fragment anisotropies from fusion-fission at near-andsub-barrier energies.
