If neutrons were observed to decay via the emission of two beta particles (as opposed to one beta and one neutrino), it would constitute evidence of Majorana neutrinos - that is, neutrinos that are their own antiparticles. The Enriched Xenon Observatory-200 has not detected such decays, but it has placed more stringent lower limits on their likelihood.
