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.
