Superconductive state of Cu-O metals

We present calculations for the superconductive state of Cu-O metals using as the pairing kernel the excitation spectrum necessary to understand their anomalous (marginal Fermi-liquid) normal-state properties. With parameters deduced from the normal state, we obtain s-state superconductivity with the right order of magnitude of Tc, a zero-temperature gap 2Δ(0)∼8 Tc and a sharply decreasing nuclear relaxation rate at Tc rather than the ''coherence peak.''
