Abstract

The impregnation of aerogel by ³He provides a new opportunity to study the effects of disorder on the properties of liquid ³He. The transport coefficients exhibit cross-over behaviour from the high-temperature regime, where inelastic ³He-³He scattering dominates, to a low-temperature regime dominated by elastic scattering of ³He off the aerogel. Within the homogenous scattering model, analytical expressions for the thermal conductivity and viscosity can be derived and are shown in graphical form for ³He in aerogel.
