Adsorption isotherms of H 2 and 4He on Rb measured with a quartz microbalance are presented. They el,early show sharp prewetting transitions. For H 2 on Rb a wetting temperature TW=17.89\_+0.04K is found. 4He isotherms below the 3. point show the characteristic frequency drop due to superfluid onset
