Electron-positron pairs have been observed in the 10.95 MeV 0- → 0+ decay in 16O. This magnetic monopole (MO) transition cannot proceed by γ-ray decay and is, to first order, forbidden for internal pair creation. However, the transition may also proceed by the emission of a light neutral 0- or 1+ boson, which might play a role in the current quest for light dark matter in the Universe.
