Beta Particle Definition: An electron or positron. The term is generally applied to an electron or positron emitted in radioactive beta decay.
By beta decay emission of an electron, a neutron within the nucleus is transformed into a proton, or by emission of a positron, a proton is converted into a neutron, changing the nuclide type. The beta particle and its associated neutrino do not exist within the nucleus prior to beta decay, but are created.
