Autoionization is a process by which atoms or molecules spontaneously emit one of the shell electrons, thus going from a state with charge {mvar|Z} to a state with charge {math|Z + 1}, for example from an electrically neutral state to a singly ionized state. Atoms can autoionize when either two or more valence electrons are excited or one or m...
