Oscillation of a stack of disks and friction between the normal and superfluid components in rotating superfluid 3He
Sonin E. B.
The parameters of the friction force between the normal and superfluid components in rotating 3He can be determined in an Andronikashvili experiment with an oscillating stack of disks. These parameters are quite different for the A and В phases, and their measurement should yield useful information about the textures which arise during rotation.
