Abstract

We report on the initial results from a measurement of the antineutrino flux and spectrum at a distance of about 800 m from the three reactors of the Palo Verde Nuclear Generating Station using a segmented gadolinium-loaded scintillation detector. We find that the antineutrino flux agrees with that predicted in the absence of oscillations excluding at 90% C.L. ¯ν_e−¯ν_xoscillations with Δm²>1.12×10⁻³eV² for maximal mixing and sin²θ>0.21 for large Δm². Our results support the conclusion that the atmospheric neutrino oscillations observed by Super-Kamiokande do not involve #x00AF;ν_e.
