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.

    As pointed out in Ref. 6, the phonon absorption rate proposed by Baym and Ebner is expected to be negligible in the temperature and concentration range considered here.Google Scholar
