The experimental thermal diffusion factors a. of' He'-Ar"' and Ne"'-Xe"' gas mixLures at different compositions of the lighter components and an isotopic natural ITIIXlure of Ne"-Ne" are estimated at the mean temperature T = 340 K by the columncalibration factor method from the available values of In q.(q. being the equilibruumseparation factor) for those mixtures at different pressures in atmosphere for eachcomposition, measured by J. M. Saviron et al. in a thermal diffusion column with thecolumn calibration factor 7',=3.946, the value (at T=340 K) derived from the formula F =68.94796 -0.3174514 7'-F-3.7l383X 10 '7"as obtained by S. Acharyya etat. It is shown that the experimental a-.'s, thus estimated with the help of F, andIn q,.., agree excellently with those due to the existing methods using molecularmodels as well as with those due to Slieher's model-independent method, so far astheir magnitudes and the trends of their variation with the mole fraction of the lightercomponents are concerned. This suggests that the present method is a unuque onewhich can safely be used to study the composition dependence of cx,- in both theisotopic and nonisotopic cases.
