abstract
The thermal conductance of a He4 film has been studied in conjunction with torsional oscillator measurements of the superfluid response. A dramatic rise in the thermal conductance is observed just above the Kosterlitz-Thouless transition temperature determined by the torsional oscillator. In agreement with the theoretical predictions of Ambegaokar et al., the thermal conductance is found to diverge as the exponential of (T-Tc)-12 for T' Tc+. 1981 The American Physical Society.
