Abstract The role of pair breaking effects on the isotope effect coefficient is investigated using the generalized Abrikosov and Gorkov theory of superconductors. It is found that the pair breaking effects enhance the isotope effect coefficient. This provides a plausible explanation for the enhancement of the isotope effect coefficient as a function of impurity concentration in yttrium-, europium-, and lanthanum-based high-T c superconductors. It may also explain the very large value of the isotope effect coefficient in Rb3C60 superconductors provided some intrinsic disorder is assumed.
