Abstract
We have investigated the electronic structure and electron correlation effects of gas phase and solid C60 by C Is photoabsorption, photoelectron, and Auger spectroscopies. Direct in situ comparison between C Is absorption spectra taken in the gas phase and in the solid reveals a close similarity between the unoccupied levels of the two phases. The same is true for the shake up satellites in the C Is XPS spectrum. The satellite due to plasmon excitations, on the other hand, appears at about 6 eV higher binding energy in the gas phase than in the solid, due to the contribution of higher multipole moments. Solid state effects play only a minor role in this new material, and electron correlation effects are predominantly intra molecular.
