Paramagnon Effect on the BCS Transition in He3

(Received February 24, 1973)

Abstract:

The theory of Berk and Schrieffer on the paramagnon-mediated interaction in nearly ferromagnetic Fermi liquids is extended so as to include triplet as well as singlet BCS pairings. The paramagnon effect on the BCS transition in liquid He3 is expressed in terms of the enhancement factor of the low temperature specific heat in the normal phase. If the usual estimate of the latter is accepted, all the singlet pairings become practically impossible.
