Abstract In this letter, we point out that the Batlogg et al. experiment does not indicate that in the oxide superconductors Ba2YCu3O7 and Ba2EuCu3O7, the isotope effect, if existed. would be very small, but instead, shows that the coupling between electron and the high frequency lattice vibration involving oxygen is weak.
