Helium II Film Transfer Rates Into and Out of Solid Argon Beakers
The purpose of this experiment is to study He II film flow over a surface whose interaction with the He is well understood. To accomplish this, we are conducting beaker-filling and-emptying experiments in which the beakers are made of solid Ar. There is a van der Waals attractive potential between the Ar and He atoms, the magnitude of which may be calculated from experimentally derived He-He and Ar-Ar potentials. This potential in turn determines the thickness of the He film on the beaker walls.
