Abstract： Going beyond both a simple perturbative theory and Hartree-Fock treatment, the Gutzwiller variational scheme is employed to clarify the possibility of electron site-pairing in doped C60. It is shown that this pairing can be induced by electron-phonon interaction rather than electron-electron interaction. Our results are supported by EPR experiments.
