Abstract
Electron-correlation in fullerene molecule are investigated in the fra mework of the Hubbard model. The variational Monte Carlo method and th e Gutzwiller wave function are used. The pairing energy of two electro ns added to a fullerene molecule or ions is calculated. Contrary to th e results obtained by second order perturbation theory the pair-bindin g is not found at intermediate interactions.
