dc.description.abstractEnWe present results of a study of neutrino oscillation based on a 766 ton/year exposure of KamLAND to reactor antineutrinos. We observe 258 [overline nu ]e candidate events with energies above 3.4 MeV compared to 365.2±23.7 events expected in the absence of neutrino oscillation. Accounting for 17.8±7.3 expected background events, the statistical significance for reactor [overline nu ]e disappearance is 99.998%. The observed energy spectrum disagrees with the expected spectral shape in the absence of neutrino oscillation at 99.6% significance and prefers the distortion expected from [overline nu ]e oscillation effects. A two-neutrino oscillation analysis of the KamLAND data gives Deltam2=7.9<sub>-0.5</sub><sup>+0.6</sup>×10-5 eV2. A global analysis of data from KamLAND and solar-neutrino experiments yields Deltam2=7.9<sub>-0.5</sub><sup>+0.6</sup>×10-5 eV2 and tan2theta=0.40<sub>-0.07</sub><sup>+0.10</sup>, the most precise determination to date.
