Resumen:
Double ionization of He by impact of multiply charged ions is studied.
Perturbative and non-perturbative regimes are analysed discriminating
the influence of post-collisional effects. A simple exponential
approximation, based on known theoretical or experimental single
ionization cross sections and Bohr and Linhard predictions of the
electron release distance, is shown to give an adequate description of
existing experimental data. Saturation effects are shown to play an
important role in the total cross section ratios of double and single
ionization for non-perturbative collisions.
