The separation of the isotopes of various kinds of rare gases in steady state DC discharges along a thin capillary is examined. The cathode region is enriched in the heavier isotopes, while the anode region in the lighter isotopes. The parameter values for the experiment includes an initial working gas pressure of 0.5-30 Torr, an inner diameter of 2-10mm for the discharging tubes, a tube length of 100-200mm and a discharging current ≲ 10 A. Theoretical calculations are also carried out incorporating two different separation mechanisms: the difference in the longitudinal diffusive friction forces on neutral species by ions, and the difference between the degree of ionization of the components. We describe a very recent progress in the experimental verifications of proposed theories and in the numerical simulation terms of atomic processes.
