  1. the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.
  2. ion, An atomic or molecular system having an excess of negative charge. Negative ions, also called anions, are formed in attachment processes in which an additional electron is captured by an atom, molecule, or cluster. They can also be formed when a molecule or cluster dissociates.
  3. ion, Positive ions are formed by atoms or molecules suffering an inelastic collision with an energetic electron in which an electron is lost from the atom or molecule (electron impact ionization). The degree of ionization of the plasma depends strongly on the electron density and energy distribution in the gas.
