COULOMB 3-BODY EFFECTS IN LOW-ENERGY IMPACT IONIZATION OF H(1S)

The different kinematical and geometrical arrangements that may be use d in (e,2e) studies are briefly reviewed. The ionization of H(1s) is c onsidered, and within the confines of a relatively simple theoretical model, it is shown how to define experimental setups where one may ext ract information on the role of Coulomb three-body effects in the inci dent and final channels. Theoretical and experimental results are pre sented for coplanar constant geometry where the focus is primarily on incident channel effects.
