A measurement of electron antineutrino oscillation by the Daya Bay Reactor Neutrino Experiment is described in detail. Six 2.9-GW_{\rm th} nuclear power reactors of the Daya Bay and Ling Ao nuclear power facilities served as intense sources of \overline{\nu}_{e}'s. Comparison of the \overline{\nu}_{e} rate and energy spectrum measured by antineutrino... Show more
