Light-emitting Decay of Neutrons (Image 2)
July 27, 2010
To observe radiative decay photons, the researchers carefully measured when the decay products in a beam of neutrons--that is, protons, electrons, antineutrinos, and sometimes photons--arrived at a detector. If radiative decay occurs, according to theory, photons and electrons will arrive 20-millionths of a second sooner than the slower protons. Antineutrinos are too weak to be detected.
