✦ Synopsis

It was found by photoemission and inverse photoemission that an energy gap with a finite density of states at the bottom (a pseudo-gap) opens at the Fermi level for alkali-doped solid C60 at the composition A3C60 (A = alkali metal). Strong electron correlation and lattice distortions (Jahn-Teller effect) are discussed as possible origins for the pseudo-gap.

The electronic structure of a CeO cluster, the soccer ball-shaped structure determined from the recent X-ray study by Hawkins et al., and of its endohedral complex KCGo were calculated using the self-consistent-field discrete variational (DV) method in the local density theoretical framework. The ca
