31. Beta decay also produces an antineutrino , which carries off variable amounts of the beta decay energy. 32. The experiment consists of eight antineutrino detectors, clustered in three locations within of six nuclear reactors. 33. Besides these three types there are their antimatter counterparts : electron antineutrinos , muon antineutrinos and tau antineutrinos. 34. Besides these three types there are their antimatter counterparts : electron antineutrinos, muon antineutrinos and tau antineutrinos. 35. Besides these three types there are their antimatter counterparts : electron antineutrinos, muon antineutrinos and tau antineutrinos . 36. Antineutrinos were first detected as a result of their interaction with protons in a large tank of water.37. The coincidence of both events positron annihilation and neutron capture gives a unique signature of an antineutrino interaction. 38. I don't quite understand how the antineutrino fits my analysis, other than in its helicity. 39. Existing geoneutrino data are a byproduct of antineutrino measurements with detectors designed primarily for fundamental neutrino physics research. 40. Under the Standard Model of particle physics, the only possible decay mode for the neutron that electron antineutrino .
