Current–phase relationship measurements in the flow of superfluid 3He through a single orifice

We report accurate measurements of the current-phase relationship in the flow of superfluid 3He through a single orifice. While ideal sinusoidal 2π-periodic Josephson behavior prevails close to T c, increasingly strong π-periodic admixture is usually observed at lower temperatures.
