The fission fragment angular distribution measurements for the {sup 13}C+{sup 235}U system have been carried out to study the entrance channel dependence and spin dependent effects in the fission fragment anisotropies. This particular combination of target and projectile leads to {sup 248}Cf compound nucleus that has been studied earlier using three other entrance channels viz. {sup 11}B+{sup 237}Np, {sup 12}C+{sup 236}U, and {sup 16}O+{sup 232}Th. A comparison of the measured anisotropy data for all the four systems, with the statistical saddle-point model and pre-equilibrium fission (PEF) model, brings out a clear signature of entrance channel dependence in fission anisotropy values, characteristic of the PEF model.
