Abstract：
Cross sections for 8 products from the fusion reaction 12C＋93Nb in the projectile energy range from 28.3 to 45.7 MeV have been obtained by off-line γ technique.The experimental results have been analysed in terms of the simplified coupledchannel model, including the coupling of the inelastic excitation and transfer channels, and statistical model for the compound nuclei. As a result, the excitation functions for the neutron emission channels are well reproduced by the CASCADE code. In the case of proton, alpha emission channels show higher cross sections than the CASCADE predictions. The transfer of alpha particles as doorways to fusion seems to be the main process which is responsible for the fusion enhancement. The experiment shows that the reaction system has large transfer cross section at subbarrier energy.
