On Fe-54 neutron cross section importance in iron

Popis výsledku v původním jazyce

The presented paper aims to evaluate the importance of Fe-54 XS in iron by means of measuring the reaction rates of the selected reactions on Fe-54 and measuring a fast neutron leakage spectra from the iron sphere of 100 cm in diameter by a stilbene scintillation detector with subsequent XS sensitivity analysis. The reactions involved in the study were Fe-54(n,p) and Fe-54(n,alpha). Measured neutron induced reaction rates in Fe-54 are compared with calculated ones in different nuclear data libraries. We show that there are notable discrepancies in Fe-54(n,alpha) reaction. The results of the leakage spectra differ significantly in various libraries, library ENDF/B-VII.1 in region 3.5-7.0 MeV gives relatively good agreement. CIELO library underestimates the result; however JEFF-3.2 overestimates results., Cf-252 with the emission rate of 9.53E8 n/s was used as a neutron source for all experiments involved.
