摘要
为合理设计基于核弹头泄漏中子被动测量核查方法的实验方案，根据假想核弹头模型，用MCNP程序计算了其泄漏中子能谱。结果表明，核材料自发裂变中子在透射出弹体后被慢化，大部分中子成为慢中子，能量小于0．5MeV。分析了这一结果对核武器现场核查中子探测技术的意义。
In order to design a way to measure the neutron spectrum of nuclear warhead in the process of nuclear weapon inspecting, neutron spectrum of a supposed nuclear warhead was calculated hy using MCNP code. The result shows that the spectrum is a moderated spectrum and the energy of mostly neutrons is lower than 0. 5 MeV. The significance of the conclusion to nuclear warhead verifying is discussed in the paper.
