摘要: It is shown that the Bardeen-Cooper-Schrieffer and Bogoliubov theories of superconductivity predict an isotope effect which same for all superconductors, so long as Coulomb interaction neglected. This demonstrated by writing system integral equations in a mass-invariant form, it does not involve finding actual solutions. The H/sub 0/, T/sub c/, energy gap at T = 0 are proportional to M/sup -1/ 2/. inclusion destroys invariance introduces deviations from -1/2 exponent. magnitude deviation depnds on particular superconductor considered.
