Reactor Neutrino Spectra | Annual Review of Nuclear and .

Nuclear reactor neutrino experiments have played a central role in neutrino physics since the 1950s. Despite the complexity of the spectra of antineutrinos emitted from reactors—namely that they result from thousands of β-decay branches of unstable fission fragments—the spectra had already been determined reasonably accurately in the 1980s.
