What is Beta decay (β+ decay)?
- In nuclear physics, beta decay, also known as β-decay, is a type of radioactive decay in which an atomic nucleus emits a beta particle (a fast energetic electron or positron), which changes the original nuclide into an isobar of that nuclide.
- For instance, in so-called positron emission, a proton is transformed into a neutron by the emission of a positron along with a neutrino, while in beta decay a neutron is transformed into a proton by the emission of an electron along with an antineutrino.
- Prior to beta decay, neither the beta particle nor the associated (anti-)neutrino are present in the nucleus; instead, they are produced during the decay process. This procedure gives unstable atoms a protons-to-neutrons ratio that is more stable.
