Scientists observe the tritium beta decay process, where a tritium nucleus decays into helium, an electron, and an antineutrino.
A giant 200-tonne spectrometer measures the energy of the emitted electrons. By analyzing the maximum energy (endpoint) of these electrons, the mass of the "missing" neutrino is inferred. 3. Key Findings (2021 Status) katrin [2021-07-09 18-28-07].mp4
