โœฆ Synopsis


The measurements of Winkel, Broese van Groenou and Gorter on the heat conduction in liquid h'elfum II have been extended to lower temperatures. At 1.1 and 1.2ยฐK the heat conduction still appears to be proportional to the cube of the slit width h in not too narrow slits. The viscosity computed from these data thus appears to have physical significance. There is a tendency for the viscosity to rise at the lowest temperatures but this effect is not so pronounced as has been found in oscillating disc and rotating viscometer experiments.

No Knudsen or Klemens effects have been found.

of the ideal gas approximation for rotons, and a qualitative roton liquid model is proposed. The temperature dependence of viscosity of the liquid model is found to correspond with the observed viscosity above 1.8ยฐK, and with the discontinuity in the temperature derivative of viscosity at the lambda
