The calculated results indicate the theoretical results are in good agreement with existed experimental data , and it is successful to predict nuclear reaction by using optical model and the semi - classical model of multi - step nuclear reaction processes in theory . en key words : optical model ; hauser - feshbach theory ; exciton model ; equilibrium processes ; pre - equilibrium processes 为了保证整个反应过程的能量守恒，我们严格考虑了反冲核效应的影响。计算结果表明，理论值与实验值符合的很好，可以认为运用光学模型及核反应多步过程的半经典模型从理论上预言核反应是很成功的。
