Abstract
The change in the logarithmic decrement upon applying heat to a freely oscillating cylinder in He II has been measured. After corrections, caused by heat, in the normal viscous contribution to the decrement the results are used to verify the prediction by Penney and Overhauser that a torque should exist on a uniformly heated cylinder about which there is a superfluid circulation. A critical comparison is made between the results of the present experiment and the prior work of Hunt who employed a quite different method.Keywords
