Abstract

We have measured fluid circulation in superfluid ³He-B. The apparatus consists of a straight vibrating wire which is mounted in a ³He cell on a rotating millikelvin cryostat operating at temperatures in the ballistic quasiparticle regime. Circulation around the wire is found to be stable only when it takes on values -h/2m₃, 0, +h/2m₃ where h is Planck's constant and m₃ is the mass of the ³He atom.
