The study is concerned primarily with three properties: specific heat $c(T)$, differential heat of adsorption $q_d$, and Ar-Ar correlation functions $g(\mathbf{r})$. These measurable functions exhibit information about the dependence of film structure on coverage and temperature.9 pages, 6 figures (revtex4).
