摘要：

We have calculated the effect of pair breaking on the isotope-effect coefficient (beta) of a superconductor. We find that, as the pair-breaking scattering rate is increased, beta also increases in absolute value. Values of beta much larger than the canonical value of 1/2 can easily be achieved even in models where the electron-phonon interaction contributes only a very small amount to the value of the intrinsic critical temperature.
