Abstract
We report on the results from a measurement of the anti-neutrino flux and s pectrum at a distance of about 800 m from the three reactors of the Pale Ve rde Nuclear Generating Station using a segmented gadolinium-loaded scintill ation detector. We find that the anti-neutrino flux agrees with that predic ted in the absence of oscillations, excluding at 90% CL <(<nu>)over bar>(e) - <(<nu>)over bar>(x) oscillations with Deltam(2) > 1.12 x 10(-3) eV(2) fo r maximal mixing and sin(2) 2 theta > 0.21 for large Deltam(2). Our results support the conclusion that the atmospheric neutrino oscillations observed by Super-Kamiokande do not involve nu (e).
