LOW-COVERAGE HEAT OF ADSORPTION Ⅱ - ALKALI METAL ATOMS ON TUNGSTEN;LENNARD JONES ATOM-ATOM INTERACTION THEORY

摘要

A comparison of experimental values of heat of adsorption (in the limit of zero coverage) for sodium, rubidium, and cesium on a tungsten substrate is made with those calculated from an adaptation of the Lennard-Jones atom-atom inter action potential to adsorption. A new method is presented for performing the necessary summations for three specific sites on the (100) and (110) planes and comparisons are made with existing approximation methods.
