Abstract
We describe a method for determining the hierarchy of the neutrino mass spectrum and through remote detection of electron antineutrinos from a nuclear reactor. This method utilizing a single, 10-kiloton scintillating liquid detector at a distance of 49–63 kilometers from the reactor complex measures mass-squared differences involving with a one(ten)-year exposure provided . Our technique applies the Fourier transform to the event rate as a function of neutrino flight distance over neutrino energy. Sweeping a relevant range of resolves separate spectral peaks for and . For normal (inverted) hierarchy is greater (lesser) than . This robust determination requires a detector energy resolution of .
