The isotope and superconducting oxides

The authors explored standard isotropic three-dimensional theory for the isotope effect with a purely electron-phonon attractive interaction. They find that additional features are necessary to account for the observed values of the isotope effect in the high-Tc superconducting oxides. Some recent proposals for possible explanations of the observed reduced isotope effects are discussed.
