摘要：

We report the room-temperature optical properties of C60 and M6C60 determined from the near-normal-incidence reflection and transmission experiments. The observed peak positions in epsilon-2(omega) for C60 and M6C60 compare well with recent band-structure calculations and suggest that the M6C60 compounds exhibit a weak hybridization between the C60 and M states, consistent with the Raman-scattering studies of M6C60. The onset of absorption across the energy gap between the highest occupied molecular orbital (MO) and the lowest unoccupied MO in C60 is measured to be 1.7 eV.
