摘要

采用组合叠层CR-39固体径迹探测器实验方法测量了加速器D（d

n）反应产生的5MeV与2MeV准单能中子能谱。进而测量了入射氘离子能量为3MeV时加速器厚铍靶9Be（d

n）反应的中子能谱

与已有的飞行时间法的测量结果基本相符。在此基础上

用该法又测量了入射氘离子能量为1.5MeV时加速器厚铍靶9Be（d

n）反应的中子能谱

结果符合较低能量氘离子与厚铍靶发生9Be（d

n）的核反应的物理过程。

Abstract

Using the CR-39 track detector stack

the mono-energetic neutron spectra for En= 5 MeV and 2 MeV from accelerator D(d

n) reaction were measured.The spectrum measurement of neutrons emitted from thick beryllium target irradiated by 3 MeV or 1.5 MeV d beams from the 4.5 MV accelerator at Peking University was performed.The results agree with that of the time-of-flight method.
