Abstract
An oscillating disc viscometer is described with which measurements have been made on the viscosities of the liquids 20Ne and 22Ne along the boiling line between 25.4 K and 32.8 K. The viscosity of 22Ne was found to be 9 ±2% greater than that of 20Ne at 25.4 K, the difference dropping to 5 ± 2% above 30 K. Classically a 5% difference is predicted at all temperatures. An estimate is made of the first quantum correction to the viscosity which compares well with this departure from the classical prediction.
