Abstract
Three puzzling features of the oxygen isotope shift in the superconducting transition of metal oxides: large values (α>0.5) in ‘‘low-’’ oxides, an overall trend to lower values for α as increases, and a negative α in Bi 2:2:2:3 at =108 K, are explained by the polaron theory of high- superconductivity.
