Abstract

The torsional oscillator helium film detector described in an accompanying paper1 gives a number of anomalous results. First, all helium film thicknesses observed were between three and ten times that expected. Second, the contribution of the vapor to the period of oscillation was much less than calculated from published values of helium viscosity. Third, the film formation curve (thickness vs. time) for film flow driven by van der Waals forces showed a sharp peak at a film thickness about 10% of the maximum film thickness.
