摘　　要：采用量子分子动力学 (QMD)、统计衰变模型 (SDM)和半经验的多模裂变模型方法计算了能量在 2 0 0MeV附近的中能质子入射重核引起裂变的裂变产物质量分布 ,得到了与实验相符合的结果 ;Based on the quantum molecular dynamics(QMD),statistical decay model(SDM)and the semi empirical multi mode fission model,the mass yield distributions of proton induced fission near 200MeV were calculated.By the experimental results of the 190MeV p+ 208 Pb and 170MeV p+ 238 U,the fitted parameters,which were used in the semi empirical multi mode fission model,can be gotten.Using these parameters in some other calculations one found that the results were in accordance with the experimental data.These methods and the fitted parameters were available.
