Abstract

Several years ago observations in our laboratory of the superfluid circulation around a fine wire stretched along the axis of a cylindrical container filled With liquid He II gave rather clear evidence of preferential metastability at quantum levels in the range from − 3 to + 3 quantum units.1 The quantum unit of circulation is h/m, where h is Planck’s constant and m is the mass of the 4He atom. Thus those observations strengthened the evidence presented by Vinen a few years earlier for the existence of quantization of circulation in superfluid helium flow around a solid obstacle.2 Our measurements at that time were all conducted with the wire and container at rest.
