摘要：

The Pauli paramagnetic susceptibility of A(3)C(60) (A=K,Rb) compounds is calculated. A lattice quantum-Monte Carlo method is applied to a multi-band Hubbard model, including the on-site Coulomb interaction U. It is found that the many-body enhancement of the susceptibility is of the order of a factor of S. This reconciles estimates of the density of states from the susceptibility with other estimates. The enhancement is an example of a substantial many-body effect in the doped fullerenes.
