Abstract
We present direct measurements of the thermal resistance between a sat urated dilute He-3 - He-4 solution and sintered silver powder between 5 and 150 mK. Measurements obtained using different sinter geometries allow us to distinguish the contribution due to the thermal boundary r esistance from that of the size-limited thermal resistance of the He-3 - He-4 solution within the pores of the sinter. The thermal boundary resistance per inverse unit volume is found to vary as T-3 and is inse nsitive to the sinter particle size.
