A Four-Body Fully Distorted Wave–Eikonal Initial State (4B-FDW-EIS) model is developed for thecase of single electron ionization of He by bare ion impact, taking into account both electrons as active ones.The projectile is considered to influence them on equal footing, in both the initial and final channels. Doublydifferential cross sections (DDCS) are calculated and effects due to electron correlation are shown for the case ofprotons impinging over He atoms.
