Neutrino emission
- An electron neutrino is a type of subatomic particle with no charge and negligible mass which is emitted from the nucleus
- The electron anti-neutrino is the antiparticle of an electron neutrino
- Electron anti-neutrinos are produced during β– decay
- Electron neutrinos are produced during β+ decay
Electron neutrino and anti-electron neutrino
The anti neutrino is denoted by a line above the symbol
Examiner Tip
One way to remember which particle decays into which depends on the type of beta emission, think of beta ‘plus’ as the ‘proton’ that turns into the neutron (plus an electron neutrino)
