Neutrino
</dt>
A subatomic
particle of zero, or near zero, rest mass, having no electric charge,
postulated by Fermi (1934) in order to explain apparent contradictions to the
law of conservation of energy in beta-particle emission.
</dd>
According to Fermi theory, the atomic nucleus in beta decay releases
energy partly in the form of electrons (beta particles) and partly in the form
of neutrinos. [[/a>|/a>]]
