• A theory for the superconducting mechanism of the high-7'. chopper oxide supercon-ductors is proposed. It is prestumed that the holes occupying tlte nonbonding oxygen2p band interact with the RVB state of the (l/.2 ,2 network through the s-d like interac-lion at each site. This gives the unusual spin singlet s-wave and d-wave pairings whosesign of interaction is not "-1-" but " -", and the usual spin triplet p-wave pairing.The gap equations have been solved to obtain the critical temperature responsible forthe high-7'. copper oxide superconductors. The possible RVB rnediated p-wave pair-ing mechanism is suggested for the copper oxide superconductors.
