Abstract
We present4He volumetric adsorption isotherm measurements on small area cells made out of Pyrex glass, and the same cells coated with partial platings of evaporated sodium. Isotherms at 4.2K and 3.99K are used to obtain quanititative results for the isosteric heat of adsorption (qst) on bare glass and qualitative results for qst on the Na-plated portion of the cells.
