Abstract

Recent site-selective oxygen isotope effect measurements in YBa₂Cu₃O₇ yield a small inverse isotope effect for ¹⁸O substitution in the plane sites. This result is consistent with an anharmonic phonon model of superconductivity, which in turn yields predictions for the site-selective isotope effects in lower-T_c compounds such as YBa_2-xLa_xCu₃O₇ and YBa_2-xSr_xO₇.
