We describe new torsional oscillator experiments on3He confined in 98.2% open aerogel. In one, we monitored the superfluid fraction of pure3He at T << Tcwhile we gradually changed the sample pressure. The resulting change in density alters ξ0of the superfluid3He relative to the distribution of the length scales (correlations) of silica in the aerogel. We observed a T = 0 normal-to-super fluid transition at a pressure of about 6.5 bar, in marked contrast to the bulk where liquid3He is superfluid at all pressures. In the second experiment, we measured the temperature dependence of the3He ρsat a pressure of 21.6 bar with different amounts of4He present in the cell. Adding 2-3%4He slightly increases both Tcand ρs. We found that for4He concentrations between 2% and 34%, the3He Tcincreases by a very small amount. However, ρs, which for pure3He in aerogel at 0.5Tcis no more than 11%, falls by another factor of 7. This behavior (constant Tc, reduced ρs) is similar to that observed in granular superconducting films where the long-range order is controlled by phase coherence between adjacent grains.
