N2 - An oxygen isotope effect is observed by a measurement of the resistivity when 16O is infstituted for 18O in the YBa2Cu3O7-δ compound. The superconducting transition temperature T c is lowered by 0.4 K upon infstitution. The results suggest that the phonon related to oxygen in the two-dimensional CuO2 plane contributes to the mechanism of high-T c superconductivity. When 63Cu is infstituted for 65Cu, no appreciable isotope effect is observed.
