On the inter-relation between ionization of light atoms by virtual and real photons
A B Voitkiv and J Ullrich
Show affiliations The correspondence between the ionization of light atoms by charged particle impact (virtual photons) and by photoabsorption (real photons) is analysed. It is shown that the `genuine' photo-like mechanism in the impact ionization of light targets can already be observed at collision energies corresponding to the Lorentz factor γ
10, but that it starts to dominate electron emission only at γ1000. It is demonstrated that the non-relativistic Bethe-Born and Weizsäcker-Williams approximations represent extremely different limits of the impact ionization but that `by chance' their results are formally close for electron emission in non-relativistic fast collisions.
