Answer:
critical temperature of superconducting element decreased with increasing atomic Maas
means superconductors are related to lattice interaction.

Answer:
The theory of Cooper pairs is quite general and does not depend on the specific electron-phonon interaction. Condensed matter theorists have proposed pairing mechanisms based on other attractive interactions such as electron-exciton interactions or electron-plasmon interactions. Currently, none of these other pairing interactions has been observed in any material.
An experiment to create a Cooper pair from positrons would make a great contribution to understanding the formation of an electron pair.
