    en.wikipedia.org/wiki/Double_ionization

    Double ionization is a process of formation of doubly charged ions when laser radiation or charged particles like electrons, [1] positrons [2] or heavy ions [3] are exerted on neutral atoms or molecules. Double ionization is usually less probable than single-electron ionization. Two types of double ionization are distinguished: sequential and ...
