Popis: Experimental investigations of double ionization provide information on the mechanism by which two electrons can be simultaneously removed from an atom. Information on the two-electron momentum distribution function of the electrons can also be obtained from the experiments. Results for the double ionization of magnesium are summarized and new (e,3e) data presented. Under a variety of experimental conditions evidence has been found for orientation and polarization effects. In addition, the recoil momentum of the residual doubly-charged ion is often large implying large momentum transfer to the core or ionizing collisions that occur close to the nucleus.
