Abstract
A closed-cycle distillation column was operated on a helium-3–helium-4 mixture in an attempt to ‘‘separate’’ the two nuclear spin states of helium-3. For the atoms in the dilute phase, a steady-state polarization 3.5 times larger than that of the equilibrium was obtained; possible ways to improve this result are discussed.Keywords
