OSTI ID:7295804
Of the three known superfluids, ([sup 4]He, superconducting electrons, and [sup 3]He), the first two are known to be described by a macroscopic wavefunction. As a direct consequence, these systems display quantisation of circulation. It has long been assumed that superfluid [sup 3]He-B is also described by a macroscopic wavefunction and should also exhibit quantisation of circulation. This thesis describes the first measurements showing that circulation is quantised in superfluid [sup 3]He-B and showing that the quantum of circulation is h/2m[sub 3] where h is Plancks constant and m[sub 3] is the mass of a [sup 3]He atom. This experiment confirms that superfluid [sup 3]He is a Cooper paired superfluid described by a macroscopic wavefunction.
