⏰ when
When was the first observation of beta decay energy loss explained with the neutrino idea?
Quick Answer
Wolfgang Pauli proposed the neutrino in 1930, and Enrico Fermi developed the beta-decay theory in 1933–1934.
The Full Story
The missing-energy puzzle in beta decay led Wolfgang Pauli to propose a new neutral particle in 1930. Enrico Fermi then developed a theory of beta decay in 1933 and 1934 that incorporated the particle, which he named the neutrino. The idea explained how energy, momentum, and angular momentum could be conserved in nuclear decay. It became a crucial part of particle physics.
