Results from the Palo Verde neutrino experiment

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 $Δm2>1.12×10−3 eV2$ 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.
