(e,2e) experiments on C60

Abstract

The ionization of C60 in gas phase has been studied by (e,2e) experiments at about 1000 eV in asymmetric kinematics and 0.6 a.u. momentum transfer. The binding energy spectrum has been compared with previous photoemission data and theoretical calculations, while the measured coincidence angular distributions corresponding to the ionization of the HOMO and HOMO-1 have been compared with calculations that account for the ionic symmetry and electronic structure of C60.
