โœฆ Synopsis

Kapitza boundary resistance between copper and helium was measured above Th and found to be an order of magnitude smaller than the value previously proposed. Hence it is too small to explain the disagreement between thermal conductivity theory and some previous results.

The reproducibility of measurements of the Kapitza conductance between electropolished copper samples and He 4 has been investigated at temperatures between 1.2 and 20 K. It is shown that the results are sensitive to the vacuum treatment to which the sample is subjected. It appears that after leavin
