摘　　要：１０ＭｅＶ中子引起的￣（２３８）Ｕ，￣（２０９）Ｂｉ，Ｆｅ和￣９Ｂｅ的次级中子双微分截面测量祁步嘉，唐洪庆，周祖英，周陈维，沈冠仁，柯尊建，孙振强，夏海鸿（中国原子能科学研究院核物理所，北京２７５－４６信箱，１０２４１３）次级中子双微分截面是核工程设...Double differetial cross sections of￣(238)U￣(209)Bi,Fe and ￣(9)Be around 10MeV are measured at 5or 6 or 8 angles between35°and120°by means of both mormal and abnormal TOF spectrometersusing (d,n)neutron source. The present resul of￣(9)Be is compared with existing experimentaldata. The data of￣(238) U and￣(209) Bi are compared with theoretical calculations. A glld agreement isachieved.
