abstract
We present a review of the antineutrino spectra emitted from reactors. Knowledge of these and their associated uncertainties are crucial for neutrino oscillation studies. The spectra used to-date have been determined by either conversion of measured electron spectra to antineutrino spectra or by summing over all of the thousands of transitions that makeup the spectra using modern databases as input. The uncertainties in the subdominant corrections to beta-decay plague both methods, and we provide estimates of these uncertainties. Improving on current knowledge of the antineutrino spectra from reactors will require new experiments. Such experiments would also address the so-called reactor neutrino anomaly and the possible origin of the shoulder observed in the antineutrino spectra measured in recent high-statistics reactor neutrino experiments.

UNVERDICTED 4representative citing papers
Thermal spectra can be produced by certain classes of emission kernels without probe thermalization, as when the differential cross section depends on angle but not on the Mandelstam variable s, providing a kernel-based criterion to distinguish genuine equilibrium from kernel artifacts.
The reactor antineutrino anomaly is revived to 2.2 sigma with the 2023 flux calculation, showing 3.8 sigma tension with gallium data that drops to 1.3 sigma when gallium uncertainties are enlarged.
Updated nuclear calculations lower the gallium anomaly significance to 2.3σ.
