摘　　要：本文以加速器驱动的脉冲中子源为照射源、铀材料为照射对象、HPGe探测器为主要探测器,测量得到了铀材料的缓发γ实验谱,再根据理论计算程序和蒙特卡罗方法得到了缓发γ计算谱。结果显示,实验谱和计算谱吻合较好,表明缓发γ能谱测量可作为铀丰度分析的一种技术手段。The accelerator-driven pulse neutron source was used as the radiation source,and the uranium material as the irradiation object.The HPGe detector was selected as the main detector.The delayed gamma spectra of uranium materials were measured.The delayed gamma calculation spectra were obtained according to the theoretical calculation program and the Monte Carlo method.Results show that the experimental spectra and the calculated spectra agree well.It indicates that delayed gamma spectroscopy can be used as a technical way for uranium enrichment analysis.
