چکیده انگلیسی
In this study, the activation cross sections were measured for 142Nd(n,α)139mCe reaction at four neutron energies between 13.57 and 14.83 MeV, which were produced by a neutron generator through 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 the gamma-ray attenuation, the dead-time, the fluctuation of the neutron flux, and low energy neutrons. The measured cross sections were compared with the published literature and the results of the model calculation (TALYS 1.4).
