摘要
Partial cross sections of two-and three-neutron evaporation channels follow-ing the fusion reaction <sup>12</sup>C+<sup>93</sup>Nb are measured for center-of-mass energies from 25.0MeV to 40.5 MeV.The total fusion cross sections and average angular momemta havebeen deduced from these cross sections on the basis of statistical evaporation model cal-culation.The fusion cross sections are well reproduced by the simplified coupled chan-nel model.The average angular momenta deduced from the partial cross section ratiosare consistent with those extracted from the coupled channel calculation.
