Measurements of the cross section for non-dissociative single ionization and the cross sections for the creation of charged fragments have been performed for50-6000ke V antiprotonand proton impact on N2, CO, CO2, and CH4. The results support the understanding of theionization phenomenon that has been achieved via measurements with fundamental chargedparticles on atoms. The present high-energy antiproton fragmentation data supply a stringenttest of the validity of the published electron-impact fragmentation data which, unfortunately, most of them fail.
