摘要
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 neutrens into angles below 5° from 7Li and 6Li nuclei have bee measured by the associated particle time of fight method.The corrections for neutron fluence attenuation,multinle scattering and fimite angle geometry are perfamed by using Mote Carlo Code.The experimental results are compared with the theoretical calcuation based on the optical model for the results provide data needed in nuclear engineering design.
