摘      要：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 C_(60).It is shown that this pairing can be induced by electron-phonon interaction rather than electron-electron *** results are supported by EPR experiments.
