Description
Based on new measurements of the ratio of cumulative spectra of $\beta$-particles ${}^{235}\text{U} / {}^{239}\text{Pu}$ performed at the Kurchatov Institute (KI), the cumulative spectra of $\beta$-particles and $\bar{\nu}_{e}$ fission products of ${}^{235}\text{U}$, ${}^{239}\text{Pu}$ and ${}^{238}\text{U}$ isotopes have been updated. The obtained spectra $\bar{\nu}_{e}$ ${}^{235}\text{U}$, ${}^{239}\text{Pu}$ and ${}^{238}\text{U}$ KI are compared with similar spectra of the Huber-Mueller (HM) model, and the spectra of $\beta-$ particles of KI are compared with the spectra of $\beta-$ particles of ${}^{235}\text{U}$, ${}^{239}\text{Pu}$, measured at the Institute Laue-Langevin (ILL), and the spectrum of $\beta-$ particles ${}^{238}\text{U}$ -- at the Technical University of Munich (TUM). The calculated inverse beta-decay yields are in good agreement with the reactor neutrino experiments data.
