Abstract

The electron-phonon coupling in fullerene C-28 has been calculated from first principles. The value of the associated coupling constant lambda/N(0) is found to be a factor 3.4 larger than that associated with C-60 Assuming similar values of the density of levels at the Fermi surface N(0) and of the Coulomb pseudopotential mu* for C-28-based solids as those associated with alkali, doped fullerides A(3)C(60), one obtains T-c(C-28) approximate to 8 T-c(C-60).
