Abstract
The cross sections of (n, x) nuclear reactions on Y, La, Ta, Pb and Bi were measured at the neutron energy 14.5 MeV by activation method with γ-ray spectra studies. The excitation functions in the range En=13.5÷14.6 MeV were investigated for reactions on Pb and Ta. The experimental results are compared both with the experimental data of other authors and with evaluated data from JENDL-3.2. The theoretical calculations for most of measured cross sections were performed with the use of STAPRE-H95 code.
