BEST Team Publishes Results of Measurements on Heat Conduction in Liquid Helium

A paper by the Boundary Effects on the Superfluid Transition (BEST) Experiment team titled "Finite-size scaling and universality of the thermal resistivity of liquid Helium-4 near T-lambda" is being published on the Jan. 17, 2003 issue of the Physical Review Letters.

The paper presents measurements of the thermal resistivity near the superfluid transition of 4He at saturated vapor pressure and at higher pressures and confined in cylindrical geometries. Measurements at six pressures P are presented. At and above T-lambda, the data are consistent with a universal scaling function valid for all P. Indications of breakdown of scaling and universality are observed below T-lambda.
