Fermi beta-decay theory

[′fer·mē ¦bād·ə di¦kā ‚thē·ə·rē]
(nuclear physics)
Theory in which a nucleon source current interacts with an electron-neutrino field to produce beta decay, in a manner analogous to the interaction of an electric current with an electromagnetic field during the emission of a photon of electromagnetic radiation.
