摘要
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 cross sections for Pb(n,x)2()3Hg,W(n,x)l82Ta and W(n,x)183Ta reactions have been measured by the activation method. The neutron fluences were determined by the cross sections of 93 Nb ( n, 2n)92m Nb reaction. The neutron energies in the measurements were determined by the cross section ratios of Zr(n,2n)89 m+g Zr and Nb(n,2n) 92mNb reactions.
