Description
Accurate prediction of reactor antineutrino spectra is essential for current and future neutrino studies. A widely used approach to determine these spectra is via conversion of the corresponding cumulative beta spectra, which are obtained from experiment. Recent results from NRC Kurchatov Institute (KI) suggest that previous measurements of cumulative beta spectra from 235U and 238U were overestimated by about 5%, so the corresponding antineutrino spectra have to be reconsidered. Based on these results, a new model of reactor antineutrino spectra was developed (KI model).We describe the KI conversion algorithm and present the results of KI model for antineutrino spectra of the main fissile isotopes.
