✦ Synopsis

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 leaving samples for a long time under a vacuum of 1(T 7 mm Hg, obtained with a getter-ion pump, fairly reproducible data may result.
