Experiments on the Formation and Surface States of Adsorbed Helium Films.
Abstract
This report contains a summary of results on (1) relaxation times in monolayer and submonolayer He3 films adsorbed on Vycor porous glass, (2) density of adsorbed helium deduced from capacitance measurments, and (3) progress on a modified POMERANCHUK cooling project. For the first item the report summarizes several recently developed phenomenological models in an attempt to explain some of the properties of He3 in Vycor porous glass. Several experiments are suggested which may help in discrimination between the various models. The second item refines this research groups view on the correlation between the density and the dielectric constant of the system under investigation based on some recent experimental evidence. In the third portion of the report contains information on the groups efforts to extend their cooling range down to helium 1.2mK. (Author)
