D603200100012 DETECTOR (SIBAR) The fission fragments were detected by two D603200100013 DeltaE(10-15 microns)-E(300-500 microns)surface D603200100014 barrier detector telescopes each of solid angle 0.7 D603200100015 msr. D603200100016 METHOD (EDE) D603200100017 ANALYSIS The fission cross section were obtained by integrating D603200100018 the measured angular distribution. The fission cross D603200100019 section assumed to be same as the fusion cross D603200100020 section for this high fissility system as the D603200100021 evaporation residue cross section are negligible. The D603200100022 fusion excitation function thus obtain for the D603200100023 present reaction was compared with the theoretical D603200100024 values based on coupled-channels code CCDEF. D603200100025 ERR-ANALYS (ERR-S) The error bar include both statistical and D603200100026 least squares fit errors. D603200100027 STATUS (APRVD) Entry approved by Dr. Alok Saxena D603200100028 COMMENT This particular combination of target and projectile D603200100029 leads to 248-Cf compound nucleus that has been D603200100030 studied earlier using three other entrance channels D603200100031 viz. D603200100032 11-B + 237-Np, 12-C + 236-U and 16-O + 232-Th. D603200100033 A comparison of the measured anisotropy data for all D603200100034 the four systems, with the statistical saddle point D603200100035 model and pre-equilibrium fission (PEF) model, brings D603200100036 out a clear signature of entrance channel dependence D603200100037 in fission anisotropy values, characteristic of the D603200100038 PEF model.
