Description

High statistics measurements of neutrino energy spectra is reported carried out at 15, 40 and 95 meters from a 2800 Megawatt reactor, using detection modules filled with 6Li-loaded liquid scintillator. No oscillations have been observed. Exclusion zones for oscillation parameters are deduced from the observed consistency of the spectra at the 3 distances. The minimum excluded values of the δm2 and sin22Θ parameters are 1x10-2 eV2 and 2x10-2 (at 90% CL), respectively. (author). 29 refs., 18 figs., 11 tabs
