When an anti-neutrino collided with a proton in the neutrino detector, the interaction produced a neutron and a positron, or an anti-electron. The resulting anti-electron would quickly annihilate with one of the electrons orbiting the nucleus, resulting in a spray of two photons. Then a stray...

Neutron Facts A neutron is a type of hadron. It consists of one up quark and two down quarks. Although the mass of a proton and a neutron are comparable, especially compared with the much lighter electron, a neutron is slightly more massive than a proton. A neutron has a mass of 1.6749...
