Determination of the Cross Sections of (n, x) Nuclear Reactions on Y, La, Ta, Pb and Bi at the Energy of Neutrons About 14 MeV

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.
