✦ Synopsis

The properties of pure 6He and 6He 4He and 6He 3He mixtures are studied within the context of the quantum theorem of corresponding states. For pure bile, it is found that there is a small, but d~[inite, region where it is expeeted to be superfluid. For the 6He 4He mixture, it isJound that there is a "').-eutectie'" temperature, approximately 1.2 K, below which it is expected that both 6He amt '*He will be part 0,1" the superfluid at all concentrations. Experiments to observe 6He superfluidity are discussed, and it is concluded that such experiments are feasible, although they may be quite difficult to earry out. Experiments are discussed to use a 6He generator (should it be possible to construct it) as a probe to study various properties ~? ['liquid and solid helium.
