摘要
用改进的多通道和无规颈断裂模型，计算了能量Ｅｎ＝０—６ＭｅＶ的中子诱发２３３Ｕ、２３５Ｕ裂变和Ｅｎ＝１．３—５．３ＭｅＶ中子诱发２３８Ｕ裂变的碎片的质量分布、动能分布和瞬发中子数分布，理论计算在定量上与实验符合较好．
In the frame of the random neck rupture and multichannel fission model,thefragment yield,average total kinetic energy distributions and prompt neutron multiplicities of the neutron induced 233,235,238U(n,f)fission covering the incident neutron energy range from thermal to 6 MeV are calculated.The theoretical results are in accord with the experimental data.
