An experiment is described in which the dependence of the Kapitza conductance of copper to He II on the dislocation density near the interface is investigated in the temperature range of 1–2 K. A dependence is found, which has not been reported before, giving support to the dislocation -based theoretical models. The Kapitza conductance for a low-dislocation-density sample is shown to be an order of magnitude below the usual values, and within the range of validity of these theories.
