| 摘 要： | 采用量子分子动力学(QMD)和统计衰变模型(SDM)分析计算了中能中子入射锕系核素引起裂变的瞬发裂变中子数和裂变中子谱。同时给出了用于本计算的一个简单的半经验的能级密度参数公式。这样,仅需要很少的输入参数便可得到合理的结果。

| Abstract: | The quantum molecular dynamics (QMD), statistical decay model(SDM) and the statistical fission theory were used to analyze the mass distribution of the fission products, the prompt fission neutron spectrum (x(E)) and theprompt fission neutron multiplicities ( vpf(E) ) caused by the intermediate energynucleon-induced fission. The semi-empirical formula of energy level density parameter used in the statistical process was also studied. Very few adjustable parameters were included in the present method. By some physical analysis, it can be thought that the present results are reasonable. The x(E) and vpf (E) can beobtained in the intermediate energy region by the present method. |
