A 3C approximation which was employed in the study of the ECC phenomenon in positron impact ionization of H 2 is now applied to positron impact ionization of helium. Our absolute triple differential cross sections are used to calibrate the existing experimental data.
We review past and present theoretical developments in the description of ionization processes in positron-atom collisions. Starting from an analysis that incorporates all the interactions in the final state on an equal footing and keeps an exact account of the few-body kinematics, we perform a crit
