Abstract

The effect (below 0.1K) of³He ppb impurities on the critical flow of⁴He through a micro-aperture has been studied for T<0.05K to investigate vortex creation at a wall. The width of the phase slip probability is found to be reduced at low temperature by 30%, implying that the³He modifies the tunneling barrier to the vortex state.
