Abstract
The isotope separation phenomenon was observed in a DG discharge of ra re gases through a thin capillary. We measured ion density and electro n temperature in the positive column of neon and krypton plasmas to un derstand the mechanisms of isotope separation. We obtained isotope sep aration factors 1.25 for Ne-22/Ne-20 and 1.6 for Kr-86/Kr-80 for the c urrent densities up to 300 A cm(-2). It is shown that one of the prese nted theories, 'ion wind', satisfactorily explains the experimental re sults.
