    "abstract": "The nuclear polarization of $\\mathrm{H}_2$ molecules formed by recombination\nof nuclear polarized H atoms on the surface of a storage cell initially coated\nwith a silicon-based polymer has been measured by using the longitudinal\ndouble-spin asymmetry in deep-inelastic positron-proton scattering. The\nmolecules are found to have a substantial nuclear polarization, which is\nevidence that initially polarized atoms retain their nuclear polarization when\nabsorbed on this type of surface",
