Abstract

A study has been made of coupling of Cooper-pair states of different binding energies by treating the intercarrier Coulomb interaction and the pairing interaction within a mean-field approximation. Illustrative calculations have been made of the Cooper-pair binding energies and their coupling effects. It is found that the Cooper-pair formation is affected in a complicated manner by the Coulomb interaction. General features of the method are discussed.
