摘　　要：利用快中子位置灵敏谱仪和伴随粒子飞行时间方法、测量了14.7 MeV中子在C和Be核上的弹性散射微分截面。用蒙特卡罗方法对中子在样品中的通量衰减、多次散射作了修正。实验数据与他人结果作了比较和讨论。The 14.7 MeV neutron small-angle elastic scattering differential cross sections of C and Be are measured by a position-sensitive spectrometer with associated particle time-of-flight method. The corrections for neutron flux attenuation and multiple scattering are performed by using Monte-Carlo calculations. The experimental results are compared with the optical- mode calculation and other measurements.
