Reines and Cowan experiment

The Reines and Cowan experiment, conducted in 1956, was the first successful detection of neutrinos, tiny particles produced in nuclear reactions like those in reactors. They used a nuclear reactor as a source and a detector with special liquids that could capture neutrinos. When a neutrino interacted with a proton in the detector, it created a neutron and a positron, which produced detectable signals. This experiment confirmed neutrinos are real particles, providing crucial evidence in particle physics and helping scientists understand fundamental components of the universe.
