Abstract
We interpret recent experimental data on double ionization of helium by impact of ions with charges between 15 and 44. An independent-electron model is used. It is shown that quantitative agreement can be obtained when the "saturation" effect in the single-electron ionization probability is accounted for at small impact parameters.Keywords
