Abstract
Some well established features found in magnetic insulating crystals are used in a possible model of high-temperature superconductors. They include electron-transfer processes to account for both conduction and antiferromagnetism, and an electron-phonon coupling similar, but of different symmetry, to that invoked in the Jahn-Teller effect. It is shown that the electron-phonon system can be decoupled by a transformation, which results in an electron-electron interaction containing BCS-like terms with a negative sign and no isotopic oxygen effect.Keywords
