The boundary resistance between superfluid ⁴He near Tλ and a solid surface
We report high-resolution measurements of the singular contribution Rb to the thermal boundary resistance between a solid surface and superfluid helium near the superfluid-transition temperature Tλ. The results confirm the observation by Murphy and Meyer that a gap between the cell end and the side...

| description |
We report high-resolution measurements of the singular contribution Rb to the thermal boundary resistance between a solid surface and superfluid helium near the superfluid-transition temperature Tλ. The results confirm the observation by Murphy and Meyer that a gap between the cell end and the
sidewall leads to an apparent finite-current contribution to Rb . In the absence of such a gap, overall
agreement of Rb with theoretical predictions is very good Remaining small differences require further
investigations. Without a sidewall gap and within our resolution we found no finite-current effects over
the range 3.9φW/cm² < Q < 221 φW/cm2.
