Abstract
Experimental measurements have been made of the reflection coefficient of phonons incident on a boundary between several dielectric crystals and liquid helium, gaseous helium, and solid neon. The measurements were made using the heat-pulse technique. A brief discussion of these results is given in terms of current theories of the Kapitza resistance.Keywords
