👤 whose
Whose discovery helped establish the first evidence for a neutrino?
Quick Answer
Clyde Cowan and Frederick Reines detected the neutrino experimentally in 1956. The particle had been proposed decades earlier by Wolfgang Pauli.
The Full Story
Clyde Cowan and Frederick Reines announced the first experimental detection of the neutrino in 1956. They observed signs of the particle near a nuclear reactor, confirming a particle Pauli had proposed in 1930 to explain missing energy in beta decay. Their work was a landmark in particle physics because neutrinos interact so weakly that they are extraordinarily hard to detect. Reines later received the 1995 Nobel Prize in Physics.
Key Facts
1.Detection announced in 1956
