✦ Synopsis

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 1.8°K, and with the discontinuity in the temperature derivative of viscosity at the lambda point.
