H. Scherrer et G. Stollhoff, EFFECTS OF THE ELECTRON INTERACTION ON THE ELECTRON-LATTICE COUPLING IN C-60, Physical review. B, Condensed matter, 47(24), 1993, pp. 16570-16575
A particular lattice coupling of the conduction-band electrons in C60
is investigated in detail. For this purpose, a model Hamiltonian is us
ed which is based on results of previous ab initio correlation calcula
tions for the molecule. It is found that this coupling is enhanced by
interaction effects of the electrons although they are only weakly cor
related.
