【摘要】 叙述了用90Zr(n,2n)89m+gZr和93Nb(n,2n)92mNb反应截面比测定D-T中子平均能量的方法。用硅探测器对中子平均能量进行监测,测量了6个不同能点的铌锆截面比值,得到了铌锆截面比与中子平均能量的关系曲线。

【Abstract】 The method of determining the energy of neutrons from T(d,n)4 He reaction by the ratio of cross sections for 90Zr (n, 2n )89m+gZr and 93Nb (n,2n)92mNb reactions is described. The cross section ratios of 90Zr (n,2n)89m+gZr to 93Nb (n,2n)92mZr reactions have been measured on several neutron energies by using silicon detectors and the plot of cross section retio of Zr to Nb against the neutron energy has been obtained.
