Abstract

We have been investigating the properties of the He-3 component in dilute He-3-He-4 solutions in Vycor glass using cw NMR techniques. According to the simple model of a Fermi gas in a restricted geometry, the porous medium significantly changes the density of states and thereby increases the zero-point energy of the quasiparticles. As a result, the He-3 quasiparticles should be progressively excluded from the Vycor glass as the temperature is lowered. We observe this effect using the strength of the cw NMR response from the confined He-3. (C) 2000 Elsevier Science B.V. All rights reserved.
