Activation cross sections for some isotopes of Zr, Mo, Br, Ta and Ce at 14.7 MeV neutrons

Abstract

The (n,p), (n, α), (n, 2n) and (n, γ) reaction cross sections on90,92Zr,92,97,98,100Mo,78,81Br,181Ta,140Ce target nuclei have been measured forEn=14.73±0.05 MeV neutrons using the activation technique. The induced γ-ray activities of the irradiated samples and their monitor foils were measured by using HPGe detector. The cross sections are compared with the existing results. The experimental uncertainties are between 3% and 10% in most cases.
