Abstract The elastic, quasi-elastic, and deep inelastic scattering of para-hydrogen in porous vycor glass have been measured in both the solid and liquid phase. At temperatures above 12 K, the H2 in the pores can be described as a bulk-like liquid with a single tightly bound layer at the pore surface. At temperatures below 8 K, the hydrogen in the pores is solidified into a crystalline structure different from that of the bulk. No indication of migration of the hydrogen out of the pores as recently proposed to explain torsional oscillator measurements, is observed. The momentum distribution of the hydrogen in the pores at both low and high temperatures is Gaussian and shows no indication of a Base condensate peak.
