We report progress achieved during decades on direct single and multiple ionization of simple atoms by electron collsion. In particular we investigate total cross sections from thresh old to high energies. We show that all experimental data compare favorably with Wannier thresh old theory. A better understanding of the ionization process one gets from the analysis of multiply differential cross sections. To this end we discuss ( e , 2 e ) and ( e , 3 e ) events.
