An oxygen isotope effect is observed in mixed-phase BiSrCaCuO superconductors when 18O is substituted for 16O. The superconducting transition temperature Tc, measured by electrical resistivity and magnetic susceptibility, is lowered by about 0.32 K for the higher-Tc (110 K) phase and by about 0.34 K for the lower-Tc (75 K) phase. These results suggest a measurable contribution to the superconductivity from phonons.
