摘要：
We calculate the equilibrium and transport properties of the mixtures using the overcomplete basis functions kψq discussed in I. The theory includes the enlarged correlation hole of a single He3 and the backflow of He4 atoms around it. The two quasiparticle scattering amplitude is the sum of two terms V=-α2m4s2n-2(k→•q→)(k→′•q→) m4nq2(1+α)m4+δmm3+δm2 the first from the interaction of the excess correlation holes and the second from the interaction of the backflows. Both terms were derived previously from macroscopic considerations by Bardeen, Baym, and Pines. © 1969 The American Physical Society.
