利用活化方法测量了14MeV中子引起的Pb(n,x)203Hg,W(n,x)182Ta和W(n,x)183Ta的反应 截面.中子注量由监督反应93Nb(n,2n)92m Nb给出,中子能量利用90Zr(n,2n)89m+g Zr和93Nb(n,2n)92m Nb反应的截面比来确定.
The reaction cross sections of Pb (n, x) 203Hg, W (n, x) 182Ta and W (n, x) 183Ta induced by 14MeV neutrons were measured by the activation method.The neutron flux was controlled by the superconducting reaction of 93Nb (n, 2n) 92m Nb, and the neutron energy is determined by the cross-sectional ratio of reaction of 90Zr (n, 2n) 89m + g Zr and 93Nb (n, 2n) 92mNb.
