摘要：

On the basis of the first-principles total-energy electronic-structure calculations, we find that the superconducting transition temperature T(c) measured for alkali-atom doped C60 fullerites under pressure has an unified linear relation to the Fermi-level density of states in a wide range of T(c). Possible mechanisms for superconductivity consistent with the finding are discussed.
