poster presentation

Recent measurements of the reactor antineutrino emission show that there exists a spectral excess in the 5-7 MeV region when compared to the Huber-Muller prediction based on the conversion method. Analysis within an alternate prediction technique, the summation method, suggests that the bump could be due to excess contributions from a certain few of the beta-decaying fission products. However,...
