Abstract

An empirical analytical expression for the ionisation cross sections is given which is in very good agreement with experimentally measured cross sections, and which is able to give a large part of the ionisation curves as a function of the energy of the impacting electrons. For high electron energies the formula is in agreement with the quantum mechanical expression for the ionisation cross section (Born-Bethe-formula).
