摘　　要：用活化法进行了13.50—14.81MeV中子能区^(204)Pb(n,2n)^(203)Pb和^(206)Pb(n,α)^(203)Hg反应截面的测量。用^(27)Al(n,α)^(24)Na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。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.
