Abstract
Angle-resolved photoemisson spectra were measured at normal emission on the cleaved (111) surface of C-60 single crystal. Valence band dispersions hav e been studied with varying photon energy of synchrotron radiation rays fro m 13.0 eV to 34.0 eV. The largest dispersions are 0.27 eV and 0.42 eV along the Gamma-L direction for the HOMO and HOMO-1 derived bands respectively. The dispersion curves coincide with the theoretical electronic structure fa irly well.
