Özet

In this study, the activation cross sections were measured for the Sm-154(n,p)Pm-154g, and Sm-154(n, p)Pm-154m reactions at several neutron energies, between 13.57 and 14.83 MeV, which were produced by the neutron generator (SAMES T-400) through the H-3(H-2,n)He-4 reaction. The production of short-lived activity and the spectra accumulation were performed by the cyclic activation technique. Induced gamma-ray activities were measured using a high resolution gamma ray spectrometer equipped with a high-purity Germanium (HPGe) detector. In the cross section measurements, corrections were made regarding the effects of gamma-ray attenuation, dead-time, fluctuation of neutron flux, and low energy neutrons. The measured cross sections were compared with data reported in literature as well as model calculations using the code TALYS 1.6. (C) 2016 Elsevier Ltd. All rights reserved.
