Abstract
We investigate hydrogen in porous Vycor glass with a torsional oscillator technique. Although our primary purpose is searching for a superfluid transition of hydrogen supercooled in Vycor, we find that hydrogen molecules which are adsorbed and liquefied in Vycor at T > T3 (triple point of bulk H2) leave the Vycor when decreasing the temperature to below a characteristic value Tc < T3. We discuss this phenomenon in terms of a free energy balance between solid/liquid hydrogen inside and outside the Vycor.
