ABSTRACT:
cf. C.A. 51, 15253f. A theory of supercond. is given, based on the attractive electron interactions from virtual phonon exchange for electron states differing by less than the phonon energy. These favor a superconducting phase when dominating the repulsive screened Coulomb interaction. The normal phase is described by the Bloch individual-particle model. The theory yields a 2nd-order phase transition and a Meissner effect in the Pippard form. Calcd. values of sp. heat and penetration depth and their temp. variation agree with expt. The energy gap goes from 3.5 kTc at 0.degree.K. to 0 at Tc. Matrix element tables for use with the theory are given.
