摘要：

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