The knowledge of reactor antineutrino spectra is necessary for the interpretation of weak-interaction experiments located at nuclear reactors. We calculate the antineutrino and electron spectra accompanying thermal neutron fission of 235U and 239Pu for various irradiation times. It is stressed that the higher energy part (E≳4 MeV) of the spectra depends sensitively on the β-decay characteristics of fission products with experimentally unknown decay schemes. We also discuss the accuracy of a semiempirical conversion of the electron spectrum into the antineutrino spectrum. The resulting ν̅ e spectra are used to calculated cross sections and reaction rates for the inverse neutron β decay, weak charged and neutral current induced deuteron disintegration, and the antineutrino-electron scattering.
