Superfluid Dissipation in RotatingHe3-B

Abstract
Additional dissipation of oscillatory superflow has been observed in uniformly rotating He3-B. The damping increases linearly with angular velocity and is interpreted in terms of vortex-induced mutual friction similar to that observed in superfluid He4. In the nonrotating state the damping is amplitude dependent, and may contain a contribution from remanent vorticity.
