摘　　要：The narrow conduction band of C_(60) leads to the breakdown of the Migdal theorem and the McMillan formula is no longer applicable.In this letter,the second-order electron-phonon vertex correction is considered to explain the superconductivity in doped C_(60) solids and the transition temperature Tc thus obtained is in accordance with the experimental results.
