Description	Journal: Journal of Physics B: Atomic, Molecular and Optical Physics We present a convergent frozen-correlation approximation (CFCA) to evaluate multiple ionization cross sections in ion-atom collisions. We have applied it to the study of double ionization of He by impact of high energy antiprotons and electrons. Comparison with experiment proves that, while the CFCA is almost as simple as an independent electron model, its accuracy is close to that of fully correlated treatments.
