Electron capture from ${\mathrm{C}}_{60}$ by slow multiply charged ions

Cross sections and fragmentation mass spectra have been measured for the capture of electrons from ${\mathrm{C}}_{60}$ by slow ${\mathrm{Ar}}^{8+}$ ions. Two mechanisms are identified: For large impact parameters multiply charged ${\mathrm{C}}_{60}$ (up to 6+) ions are produced, while for smaller impact parameters the ${\mathrm{C}}_{60}$ 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 found to be somewhat larger than the geometrical ${\mathrm{C}}_{60}$ cross section.
