✦ Synopsis

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