Positron and electron impact multiple-ionization of rare gases

We present a theoretical treatment of the multiple-ionization by light projectiles, which is valid in an extended energy range (from near threshold to the keV region). It covers the direct ionization and the post- collisional electron emission, and takes into account charge and mass effects: project...
