Abstract A static equilibration method was used to measure the single stage separation factor a of isotopic pairs in the vapor liquid equllibrium of Ar, N/ sub 2/, and O/sub 2/ below the boiling point. Since the correspending isotopic mixtures are supposed to be ideal, the vapor pressure ratio of the studied isotopic liquids is identical to alpha , The separation factors at the boiling point were found to be the following: Ar/sup 36/ - Ar/sup 40/, alpha = 1.0060 plus or minus 0.0001; O/sub 2//sup 16/ -O/sup 16/O/sup 18/ alpha = 1.0050 plus or minus 0.0001; and N/sub 2//sup 14/ - N/sup 14/N/sup 15/, alpha = 1.0037 plus or minus 0.0001. The temperature dependence was established in all cases in a relatively narrow range of temperatures. A discussion of the argon results in the light of the quantum theorem of corresponding states is given (auth)
