Inner-shell photodetachment of C$_{60}^-$

POSTER

Abstract

First photodetachment spectroscopy on negative ions of C$_{60}$ has been conducted, using the merged ion-photon beam apparatus at the ALS with photon energies from 20eV up to 320eV. Multiple electron ejection was substantial at all photon energies, allowing product charge states up to 3+ to be measured. Fragmentation into cations of C$_{58}$, and C$_{56}$, was also studied. The relative strengths of the 7 observed product channels and absolute cross sections were measured at selected energies in this range. We find some structure that differs significantly from previous results in photoionization experiments on C$_{60}$ cations [S.W. J. Scully {\it et al.}, Phys. Rev. Lett. {\bf 94}, 065503 (2005).].
