We have previously described a resonance involving the adiabatic motion of
He-4 from a superleak into a reservoir. We consider here the case of He-3-H
e-4 mixtures and show some preliminary results for rho(s) for confinement t
o a film with thickness L = 0.0483 mu m. We relate this to the behavior exp
ected from correlation-length scaling. (C) 2000 Elsevier Science B.V. All r
