Abstract
A new model for the pairing mechanism in the ceramic superconductors is presented. Like the magnetic models, we assume the limit of large correlation energies for the Cud electrons. We postulate that the pairing of the Op conduction holes occurs viad−d orbital excitations within thee g manifold of thed hole of Cu++, which is split because of tetragonal or lower symmetry at the Cu sites. This valence conserving charge degree of freedom has been ignored in the magnetic pairing models. Thed−d excitation model may provide a simple qualitative understanding of many experimental results.

In relation to this work, a transmission study of YBa2Cu3O7−δ has been initiated [28]. Absorption maxima within the charge transfer gap have been found, in analogy to thed−d transitions in the spectra of magnetic 3d oxides [39]. The lowest maximum is found near 0.5 eV
