Abstract：
The cross sections for Ba(n, x)¹³⁴Cs,¹³⁴Ba(n, 2n)¹³³Ba,¹⁴⁰Ce(n, 2n)¹³⁹Ce,¹⁴²Ce (n,2n)¹⁴¹Ce and ²³Na(n,2n)²²Na reactions have been measured by the activation method relative to ⁵⁴Fe(n,p)⁵⁴Mn reaction in the neutron energy range of 13.50-14.80MeV. The measured results are compared with published data. Neutron energies are determined by the method of making cross section ratios of ⁹⁰Zr(n, 2n)^89m+gZr and ⁹³Nb(n,2n)^92mNb reactions.
