David Eppstein,Zvi Galil,Raffaele GiancarloA feature inherent to the motion of two electrons in a nuclear field is the threshold be­haviour of the total cross section for the ejection of one electron from a hydrogenic target upon electron impact.

https://doi.org/10.1007/978-1-4612-3352-7The study of the double ionization of atoms or molecules by electron impact is a powerful tool in investigating finer details of the ionization process. This double ionization by electron impact is due to different processes:.We restrict here to the double ionization of helium by electron impact which only involves direct process.
