摘要
测量了8.17 MeV中子与天然铁作用的次级中子双微分截面,测量角度为30°~150°,共11个角度,采用n-p散射作为标准截面进行归一。测量数据用Monte-Carlo方法进行了模拟,以进行中子注量衰减、多次散射和有限几何修正。将测量结果与评价数据及其它测量数据进行了比较与分析。实验测量结果对数据评价、理论模型检验及实际应用等具有重要的意义。
The secondary neutron emission double-differential cross section（DDX） of natural iron induced by 8.17 MeV neutron was measured.The neutron emission energy spectra were measured at 11 different angles from 30° to 150°.The results were normalized to n-p scattering measurement.The measured data were analyzed by Monte-Carlo simulation for the corrections of neutron fluence attenuation,multiple scattering and finite geometry.The measured results were compared with the evaluated data and the other measurements.The experimental result will contribute to the nuclear data evaluation,the theoretical model calculation and the nuclear data applications.
