摘要：

Oxygen isotope effect studies were performed on the (Y1-(x)Pr(x)) Ba2Cu3O7-delta system for 0 less-than-or-equal x less-than-or-equal-to 0.5. With increasing x, and falling transition temperature, we find a large isotope effect, the coefficient alpha-o is approaching 0.5. The results show the importance of the electron-phonon interaction for the superconductivity of these compounds.
