Abstract
The distorted-wave Born approximation is applied to near-threshold ionization of atomic hydrogen and helium. A model is used which includes the post-collision interaction, electron exchange, electron capture and shake-off. The results of this model are in reasonably good agreement with experimental data. The relative importance of different types of ionization mechanisms is investigated.Keywords
