Abstract:
Angular distributions of fission fragments were measured for a series of compound nuclei formed in the bombardment of 169Tm,175Lu,181Ta,W,Re,Pt,197Au,Pb and 209Bi by 12C ions with mica track detectors and gold surface barrier silicon detectors.All the measured angular distributions can be fitted satisfactorily by the theoretical formula based on saddle point model.The variation trend for K2 with the excitation energy increasing was given at various ranges of the fission parameter Z2/A.
