Phonon-Quasiparticle Interactions in Dilute Solutions of He3 in Superfluid He4. II. Phonon Boltzmann Equation and First Viscosity
Abstract
We construct the phonon Boltzmann equation taking into account previously calculated phonon-He3 scattering and absorption processes; when phonon-phonon interactions can be neglected this equation is exactly soluble. The first viscosity of solutions containing 1.3 and 5% molar concentrations of He3 is calculated from this equation for T<~0.6°K.
