摘要
In superconducting M(3)C(60), where M is a monovalent metal, t(lu) molecular states form a half-filled narrow energy band with bandwidth from 0.3 eV to 0.6 eV. High energy intramolecular phonons are strongly coupled to electrons. We are studying the effects of electron correlation for such a narrow band, and the effects of first corrections to Migdal's theorem for such high energy phonons on the transition temperature.
