The Free Surface of Rotating 4He Thick Films
Surface profiles of He II with an initial thickness of 6–50 μm were measured for a rotating and stationary cylindrical container. Equilibrium porfiles are consistent with <vSθ> = vnθ = ωr, vnr > 0 and <vsr> < 0. Metastable depressions created after sudden spin-up appear to be a superfluid vortex with a circulation of several hundred h/m.
