摘要
采用蒙特卡罗方法研究252Cf自发二分裂变过程中裂变碎片核发射的中子能谱和中子角分布。文中给出了模拟计算的条件、步骤和模拟结果,详细分析了实际测量中252Cf自发二分裂变碎片核发射的中子能谱之间的相互干扰。该模拟分析与测量特定裂变碎片核的发射中子谱的实验研究密切配合,对相关实验具有指导性参考价值。
The neutron angular and energy distributions were calculated by using Monte- Carlo method for a given 252^Cf binary fission fragment. The conditions and steps of the calculation were specified, and the results were presented. The interference of the neutrons from one fragment to those from the complementary fragment was analyzed. This simulation could work with the measured neutron spectra for a given fission fragment and give a theoretical reference for the relevant experimental measurements.
