摘要：

We investigate roles of electron-electron and electron-phonon interactions in alkali-metal-doped C-60, A(x)C(60) (A=K, Rb, etc.). It is shown that both interactions are important to observed anomalies. We find that A(2)C(60) and A(4)C(60) are nonmagnetic semiconductors and the-band gaps in these materials are cooperatively formed by the electron-electron and electron-phonon interactions. On the other hand, we find that A(1)C(60), A(3)C(60), and A(5)C(60) are on the border of the metal-insulator transition.
