Our paper on the isotope effect in high-temperature superconductors with cation substitutions presents acomprehensive analysis rooted completely in the experimental evidence. In this Reply we show that pairbreakingdisorder, isotope effects, doping-induced variations in Tc and in the magnetic penetration depth,Coulomb’s law, and Anderson’s theorem are treated with correct physical and mathematical fundamentals. Incontrast, the theory fostered in the Comment by Alexandrov and Zhao contradicts several specific experimentalfacts, eight of which are briefly discussed. Their Comment also uncritically repeats a previously discreditedassertion of an isotope effect in the superconducting carrier mass, incorrectly assumes that cation dopingcontinuously varies intrinsic superconducting parameters, unjustifiably assigns importance to data fromsamples with serious quality problems, and renders a false estimate of the pair-breaking strength.
