What is Detection of Antineutrinos / Neutrinos – Definition
Since neutrinos do not ionize matter, they cannot be detected directly. The antineutrino detection is based on the inverse beta decay. Detection of Antineutrinos. Material Properties
Since neutrinos do not ionize matter, they cannot be detected directly. The antineutrino detection (1995 Nobel Prize for Frederick Reines and Clyde Cowan) is based on the reaction:
This interaction is symmetrical to the beta decay of free neutron, therefore it sometimes referred to as inverse beta decay. All detection methods require the neutrinos to carry a minimum threshold energy of 1.8 MeV. Only antineutrinos with an energy above the threshold of 1.8 MeV can cause interactions with the protons in the water, producing positrons and neutrons.
