Abstract
Measurements of the Kapitza conductance by the ac technique between 1.2 and 1.8 K are reported for thin oriented single-crystal disks of high-purity gallium. The data show convincing evidence that the conduction electrons play a dominant role in the transmission of heat across the metal-He-II interfaces.Keywords
