SUPERCONDUCTIVITY OF M(3)C(60) WITHIN ELIASHBERG THEORY

The important feature of the alkali-metal-doped C-60 is that the intra molecular high-frequency vibration modes arising from the covalent int eraction and the intermolecular low-frequency vibration modes arising from the weak Van der Waals interaction both play important roles in t he properties of superconductivity. We propose a two-peak form for the phonon density of states. By solving the Eliashberg equations we get the formula for the reduced gap 2 Delta(0)/kappa(B)T(c) and the transi tion temperature T-c which are all in accordance with the experimental values.
