Abstract ： An effective attractive Hubbard model is applied to explain the observed non-Korringa relation in doped fullerenes, which leads to a reduced Pauli susceptibility. The results basically agree with the experiments for K3 C60 , Rb3 C60 and RbCs2 C60 . It implies that the pair correlation on site possibly plays an important role in the normal state for doped fullerenes.
