| Abstract: | 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 Tc, increasingly strong π-periodic admixture is usually observed at lower temperatures. |
| Keywords: | Current–phase relationship 3He superfluid Josephson effect |
