Abstract

An isotope effect has been searched for in the high- $T_{c}$ superconductor $Y {Ba}_{2} {Cu}_{3} O_{7 - δ}$ through substitution of ${}^{18}O$ for ${}^{16}O$ . No shift in the superconducting transition temperature $T_{c}$ is observed by electrical resistivity or magnetic susceptibility measurements. We discuss the implications of this result for mechanisms of superconductivity in the high- $T_{c}$ oxides.
