CLOSE SIMILARITY OF THE ELECTRONIC-STRUCTURE AND ELECTRON CORRELATIONIN GAS-PHASE AND SOLID C-60

We present a study of the electronic structure and electron correlatio n effects in gas-phase and solid C60 clusters. Direct in situ comparis on of C 1s absorption spectra taken in the gas phase with those from s olid C60 reveals a close similarity. This is also true for the shake-u p satellites in the C 1s x-ray-photoelectron spectrum. The main conclu sions are that solid-state interactions play only a minor role in this new material, and electron correlation effects are predominantly intr amolecular.
