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
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 t
An apparatus for the measurement of the viscosity of liquids and gases, interchangeably, is described. Measurements of the viscosity of liquid helium made with this apparatus are reported. The measurements were made over the temperature range from 1.2 to 4.0oK.
