摘要：

New (v) over bar (e)e scattering experiments aimed at sensitive searches for the v(e) magnetic moment and projects to explore small mixing angle neutrino oscillations at reactors require a better understanding of the reactor antineutrino spectrum. Six components which contribute to the total (v) over bar (e) spectrum generated in a nuclear reactor are considered. They are beta decays of the fission fragments of U-235, Pu-239, U-238, and Pu-241 and decays of beta (v) over bar (e) emitters produced as a result of neutron capture in 238U and in accumulated fission fragments which perturb the spectrum. For antineutrino energies of less than 3.5 MeV and for each of the four fissile isotopes, the time evolution of spectra is given during fuel irradiation and after the irradiation is stopped. The relevant uncertainties are estimated. Small corrections to the ILL spectra are considered. (C) 2004 MAIK "Nauka/Interperiodica".
