摘要：
The angular distributions for the fission fragments ofU （n, f） reaction betweenE=0.86 MeV and 1.80 MeV have been studied by means of nuclear emulsion loaded withuranium and solid state nuclear track detectors. The fission fragment angular distributionsand the fission cross sections have been calculated by using Hauser-Feshbach theory withwidth fluctuation correction on the basis of the model of effective single fission barrier.The results obtained indicate that in the energy dependence on the anisotropy there existsa gross structure.
