Robinson, L B

Thermodynamic and transport properties of Rb and Cs vapors were determined from theory, supplemented by experimental results. The situation for which results were obtained involves negligible ionization of the alkali atoms. The model used was imperfect gas obeying the virial equation of state. The second virial coefficient was considered adequate to account for deviations from the ideal behavior in the temperature and pressure range under consideration. It was assumed that the vapors are comprised of alkali atoms whose interactions are the pairwise LennardJones 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 were 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. (auth)
