Measurements of activation cross-sections for the 19F(n, α)16N reaction for neutrons with energies between 13 and 15 MeV

Abstract

In this study, activation cross-sections were measured for the F-19(n, alpha) N-16 reaction at six different neutron energies from 13.5 and 14.9 MeV. The fast neutrons were produced via the H-3(d,n)(4) He reaction on SAMES T-400 neutron generator. The cyclic activation technique was used. Induced gamma activities were measured by a high-resolution gamma-ray spectrometer with high-purity germanium (HpGe) detector. Measurements were corrected for gamma-ray attenuations, random coincidence (pile-up), dead time and fluctuation of neutron flux. Results were compared with the previous works. (c) 2005 Elsevier Ltd.
