JAHN-TELLER EFFECT AND SUPERCONDUCTING MECHANISM OF THE HOLE-DOPED C₆₀ SOLID

A possible superconducting mechanism of the hole-doped C₆₀ solid is discussed. Under the assumption that the superconductivity results from the strong coupling between electrons at Fermi surface and intramolecular vibrations, a simple expression for the electron-phonon coupling parameter \lambda is derived. The related transition temperature is estimated and can be much greater than that of the alkali-metal-doped C₆₀ solid.
