【摘要】 用活化法进行了13.50—14.81MeV中子能区204Pb(n,2n)203Pb和206Pb(n,α)203Hg反应截面的测量。用27Al(n,α)24Na反应作为中子注量标准。中子能量用锆、铌截面比测定。所得结果和有关文献的结果作了比较。

【Abstract】 The cross sections of 204Pb(n,2n)203Pb and 206Pb(n, α)203Hg reactions have been measured by using the activation method in the neutron energy range of 13.50-14.81 MeV. Neutron fluence dose was calibrated with the cross sections of 27Al(n,α)24Na reaction and neutron energies were determined by using the cross section ratios of 90Zr(n,2n) 89m+gZr to 93Nb(n,2n)92mNb reactions. The results obtained are compared with the published data.
