Özet

In this study, activation cross-sections were measured for the F-19(n,p)O-19 reaction at six different neutron energies from 13.5 and 14.9 MeV. The fast neutrons were produced via the H-3(d,n)He-4 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. For these reactions, statistical model calculations for which the pre-equilibrium emissions effects are taken into consideration were also performed between 13.60 and 14.86 MeV energy range. Results were compared with the previous works and shown good agreement. (C) 2003 Elsevier Science Ltd. All rights reserved.
