Abstract
The thermal conductivity of sodium-chloride crystals containing silver colloids has been measured between 0.2 and 2°K. The effect of a transition from Rayleigh scattering to geometrical scattering is readily apparent in the results. Good agreement is obtained between the experimental values and thermal conductivities which were calculated assuming the colloids to be monodisperse spheres and using the bulk elastic constants for silver.Keywords
