摘要：

The K+-ion optic phonons couple strongly to carriers on Co-60 molecules and can lead to an effective attraction at low energies. The fcc lattice is a frustrated lattice for a charge-density-wave state, opening the door to superconductivity. The competition between these instabilities is shown explicitly within mean-field theory.
