Abstract
We report the results of a quartz microbalance study of the multilayer adsorption of H2 and D2 on sodium and on rubidium. On sodium H2 and D2 display the well known phenomenon of triple-point wetting. Interestingly low temperature adsorption isotherms of H2 on the evaporated Na surface show sharp layering transitions. On rubidium a weaker substrate H2 and D2 undergo a wetting transition in the liquid phase followed by sharp presetting transitions away from liquid-vapor coexistence. The prewetting phase diagram of H2 on Rb has been quantitatively mapped out.
