I report on the initial results from a measurement of the anti-neutrino flux and spectrum from the three reactors of the Palo Verde Nuclear Generating Station using a segmented gadolinium-loaded scintillation detector at a distance of about 800 m. We find that the anti-neutrino flux agrees with that predicted in the absence of oscillations, excluding at 90% CL ν̄e−ix oscillations with Δm2>1.12×10−3eV2 for maximal mixing and sin2 2θ>0.21 for large Δm2. Our results support the conclusion that the atmospheric neutrino oscillations observed by Super-Kamiokande do not involve νe. I will also give a short overview of the present status of the next generation long baseline reactor neutrino experiment, KamLAND.
