## Sound propagation has been studied in He H films adsorbed on alumina powder grains (Ale03). Sound velocity and adsorption isotherm data provide evidence that surface tension forces can exceed the van der Waals forces as the film thickness increases.

The conductivity of electrons localized in a quasi-one-dimensional channel over super uid helium in the presence of a magnetic ΓΏeld normal to the surface is studied by means of the memory function formalism. The electron mobility along the channel is shown to be a nonmonotonic function of temperatur
