Abstract
We have studied circulation in superfluid He-3-B with a vibrating wire . We find that the circulation quantum equals h/2m3 to within experime ntal error at several pressures. We have also measured circulation in rotating superfluid He-3-B, and have observed a precessional motion of a single vortex line. Finally, we have found the unexpected result th at circulation around the wire does not affect the pair-breaking criti cal velocity.
