THERMODYNAMIC AND TRANSPORT PROPERTIES OF RUBIDIUM VAPOR AND CESIUM VAPOR

Abstract

Thermodynamic and transport properties of Rb and Cs vapors are determined from theory, supplemented by experimental results. The situation for which results are obtained involves negligible ionization of the alkali atoms. The model used is an imperfect gas obeying the virial equation of state. The second virial coefficient is considered adequate to account for deviations from the ideal behavior in the temperature and pressure range under consideration. It is assumed that the vapors are comprised of alkali atoms whose interactions are the pairwise Lennard-Jones (6 - 12) type. On the basis of the 2 parameters which occur in the Lennard-Jones potential for interactions between some alkalis and noble gas atoms and the known parameters for the noble gas atoms, the parameters are estimated for the alkalis. From these parameters the desired thermodynamic and transport properties of Rb and Cs vapors are obtained. Numerical values are given for the important properties.
