In the present work we calculate multiple ionization cross sections, as a function of the orientation of the molecular axis with respect to the ion beam, for impact of highly charged ions on N2 and O2 molecules. We use different approaches to obtain the single ionization probabilities that are necessary to compute these quantities into the Independent Electron Model. The influence of the molecular orientation on differential cross sections is analized. An adequate description of existing data is obtained.2 and O2 molecules.
