Abstract

We have performed an experiment designed to observe superfluid film flow in ³He. Our apparatus measures flow rates as small as 4ȕ10^-5mm³/s onto a horizontal surface located a distance h above a reservoir. Results indicate that when h is several millimeters no flow is detected. However when h is less than 2.5 mm from the horizontal surface, film flow is observed at temperatures well below Tc.
