【Abstract】 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.更多还原
