Abstract

Phonon-3He quasiparticle scattering times in dilute mixtures of 3He in liquid 4He have been determined using the fast-heat-pulse technique. These scattering times were found to be in reasonably good numerical agreement with those theoretically calculated for Rayleigh-like scattering by Baym and Ebner. The scattering is shown to exhibit a strong pressure dependence.
