Özet

In this work, cross sections were measured for the ¹⁴⁰Ce(n, α) ^137mBa (T _1/2 = 2.552 min) reaction at neutron energies from 13.57 to 14.83 MeV. The neutrons were produced via the ³H( ²H,n) ⁴He reaction on a neutron generator using a solid Ti-T target. The activation technique was used, and induced gamma activities were measured by a high resolution gamma-ray spectrometer. Corrections were made for the effects of gamma-ray attenuation, random coincidence (pulse pileup), coincidence summing, dead time, neutron flux fluctuations, and low-energy neutrons. The measured cross sections were compared with statistical model (TALYS code) calculation results and the experimental data in the available literature.
