dcterms:description
Irradiation of material with quasi-monoenergetic neutrons with energies up to 35 MeV is routinely used for cross-section measurement. Neutron irradiation, gamma measurement, and cross-section extraction are three steps in obtaining the final cross-section, each of them contributing to the final uncertainty. The nature of the spectra, which consists of the monoenergetic peak and the continuum at lower energies, makes the extraction of the cross-sections a non-trivial problem and different methods of extraction are used. In this paper, we identify the main sources of uncertainties, discuss possible improvements, and address the differences between some commonly used methods of cross-section extraction.
