Cmcm. Vanwoerkens et al., POLARIZATION OF HE-3 AND HE-3-HE-4 MIXTURES WITH THE CASTAING-NOZIERES METHOD, Czechoslovak journal of Physics, 46, 1996, pp. 217-218
We describe experiments employing a strongly improved technique to pre
pare highly polarized He-3 and He-3-He-4 mixtures. The polarization is
obtained with the rapid melting method. A novel design cell using Ves
pel SP-1 (a sintered form of polyimide) can reach relative volume chan
ges of 17 %, which is required to decompress a completely solid He-3-H
e-4 mixture to a completely liquid state at 23 bar.
