Abstract

We report preliminary measurements of the influence of 3 He in the adsorption of 4 He to a cesiated substrate by the use of quartz crystal resonance techniques. When compared with the case of pure 4 He, the presence of 3 He in the apparatus induces the wetting of the mixture film to Cesium at low temperatures. The wetting is hysteretic, beginning at a concentration-dependent Tc on cooling with continued wetting for T>Tc on warming. The temperatures Tc are given as a function of the total concentration of 3 He in the apparatus.
