Electron neutrino

Theelectron neutrino( ν ) is anelementary particlewhich has zeroelectric chargeand a spin of 1⁄2. Together with theelectron,it forms the first generation ofleptons.It was first guessed byWolfgang Pauliin 1930. It was accounted for missingmomentumand missing energy inbeta decay.Later it was discovered in 1956 by a team led byClyde CowanandFrederick Reines(seeCowan–Reines neutrino experiment).
