Using the same experimental methods as in earlier work, studies have been made of the Kapitza conductance between liquid He 4 and clean surfaces of annealed molybdenum and beryllium samples at temperatures between 1 and 2 K. The conductance of molybdenum at 1.5 K is 75 W m "2 K -I and for beryllium

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
This paper reports on some experiments on the influence of a number of methods of surface treatment on the Kapitza conductance between copper and He 4 at not very low temperatures. Attention is paid to the magnitude, the temperature dependence, and the reproducibility between different samples. The
