Abstract
Based on new measurements of the ratio of cumulative spectra of β-particles 235U/239Pu, performed at the Kurchatov Institute (KI), the cumulative spectra of β-particles fission products of 235U, 239Pu and 238U isotopes have been updated. The presented β-particles spectra 235U, 239Pu and 238U KI are compared with similar spectra measured at the Institute Laue–Langevin (ILL), and the spectrum of β-particles 238U KI – with the measurements performed at the Technical University of Munich (TUM). It is shown that the ILL ratio of β-particles spectra 235U/239Pu is mistakenly overestimated by ≈5.4%.
