Abstract

The problems related to the formal theory of electron-atom ionization were studied. An integral representation for the ionization amplitude, which was free of ambiguity and divergence problems, was presented. Electron impact ionization of atomic hydrogen was considered, and it was assumed that the proton was infinitely heavy compared to the electrons and remained at rest. The results show that the proposed representation is readily applicable to extract the exact breakup amplitudes in direct calculations of general few-body systems.
