Partial cross sections of two-and three-neutrons evaporation channels following the fusion reaction 12C+93Nb have been measured for center-of-mass energies from 25.0 to 40.5 MeV by off-line γ technique. The total fusion cross sections and average angular momenta as a function of energy have been deduced from these cross sections on the basis of statistical evaporation model calculation( CAS CADE). The fusion cross sections are well reproduced by the simplified coupled channel model (CC FUS). The average angular momenta deduced from the partial cross section ratios are consistent with that extracted from the CCFUS calculation.
