Abstract
It is shown that mutual-friction calculations for 4He are clarified by relating the force on the excitations to that on the background fluid rather than to that on the superfluid component. The shape of the container does not influence the calculation as had previously been thought. Calculations by various other authors, on the critical behaviour of the Hall-Vinen parameters, are discussed and inter-related.Keywords
