摘要：

Cross sections and fragmentation mass spectra have been measured for the capture of electrons from C60 by slow Ar8+ ions. Two mechanisms are identified: For large impact parameters multiply charged C60 (up to 6+) ions are produced, while for smaller impact parameters the C60 is broken into smaller fragment ions. The absolute cross sections are consistent with an over-barrier picture for long range capture, while the destruction cross sections are round to be somewhat larger than the geometrical C60 cross section.
