A small twelve-stage gaseous dlffusion cascade was built for the measurement of the barrier separation factor for uranium isotopes. The experiments were performed in a wide range of operating conditions, with the mass flow rate of gaseous uranium hexafluoride at the separation inlet of the order of 1 g/sec under mean operating conditions. The experimental results are presented and compared with theory. Within the precision of the measurements, the theoretical values can be adjusted to the experimental data by choosing an adequate fictitious mean pore radius, different from the permeability pore radius, and an adequate value of the mass transfer boundary layer thickness. This adjustment, however, is not entirely satisfactory throughout the whole range of data. (J.S.R.)
