Abstract

In this study, the activation cross sections were measured for the ¹⁵⁴Sm(n,p)^154gPm, and ¹⁵⁴Sm(n,p)^154mPm reactions at several neutron energies between 13.57 and 14.83 MeV, which were produced by the neutron generator (SAMES T-400) through the ³H(²H,n)⁴He 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.
