SPECTRUM OF ELECTRONIC REACTOR ANTINEUTRINOS

The spectrum of reactor antineutrinos has been obtained in the energy range E(nu) = 0-9 MeV. The spectrum for E(nu) greater than or equal to 2 MeV has been measured in an experiment performed at the Rovno nucle ar power plant. In this experiment, 174000 positrons from the reaction <(nu)over bar(e)> +p --> e(+) + n have been detected with a RONS scin tillation spectrometer. The results of refined calculations that take into account radiation from fission fragments and from the products of radiative capture of neutrons are presented for the spectrum in the r egion E(nu) less than or equal to 2 MeV.
