An experiment was undertaken on the isotopic separation by DC cataphoresis of neon gas of natural isotopic abundance, which proved through analysis of gas sampled after stabilization that the heavier isotope <SUP>22</SUP>Ne became enriched in the region of cathode, and the lighter isotope <SUP>20</SUP>Ne in that of anode. The maximum separation factor obtained by this means was 1.072. The effect on the obtainable separation factor brought by differences in experimental conditions was examined using a capillary tube of 3.7mm diameter and of 100 and 150mm alternative lengths, with discharge current parametrically varied between 4 and 8A in 4 steps and discharge pressure between 5 and 30 Torr in 5-6 steps. From the experimental data thus obtained, a non-dimensionalized equation was derived giving the enrichment factor as function of experimentally determinable values--e.g. cross section, discharge current and pressure, strength of electric field and electron drift velocity.
