Photo-multidetachment and Fragmentation of C60 anions

Abstract

Absolute single-photon multi-electron ionization and fragmentation cross sections for C-60 ions are measured for the first time. It is determined that the excess electron in the anion causes a significant increase in cross section and an overall energy scaling, but otherwise has little effect on the observed structure. Appearance energies (apparent thresholds) of the fragmentation products are also observed to be significantly lower for the anion, as compared to the neutral molecule. © Published under licence by IOP Publishing Ltd.
