Abstract

Flow of ${\mathrm{He}}^{4}$ films adsorbed on graphite is qualitatively different from flow on other substrates. We observe two distinct types of "onset" phenomena. Type $A$ appears for films thicker than 2 layers at temperatures ${T}_{A}$ within 20 mK of ${T}_{\ensuremath{\lambda}}$. In thicker films there is an additional more dramatic increase (onset $B$) at lower $T$. ${T}_{B}$ varies with $\frac{P}{{P}_{0}}$, and is higher than temperatures of "superfluid onset" reported previously.
