利用伴随粒子飞行时间方法，测量了入射角为５°以下的快中子在７Ｌｉ和６Ｌｉ核上的弹性散射截面．用蒙特卡洛方法进行了注量率衰减、多次散射和有限角分辨修正．对实验结果与理论计算进行了比较，其数据可为核工程设计提供必要的核参数．
The elastic scattering cross sections of fast neutrons with 7Li and 6Li nuclei at angles of incidence of 5 ° were measured by using the method of time-dependent particle time-of-flight. Focused rate attenuation, multiple scattering and finite angle resolution correction were performed with Monte Carlo method. The experimental results and theoretical calculations were compared, and the data provided the necessary nuclear parameters for nuclear engineering design.
