Adsorbed Xenon and the Production of Hyperpolarized 129Xe

Adsorbed Xenon and the Production of Hyperpolarized 129Xe

We show that it is possible to induce a large nuclear spin polarization in 129Xe adsorbed on a silica gel substrate using 3He as a relaxant, in a reasonable time. We also describe the complete production cycle for the generation of large quantities of hyperpolarized xenon from xenon gas by a cryogen...

Zusammenfassung:We show that it is possible to induce a large nuclear spin polarization in 129Xe adsorbed on a silica gel substrate using 3He as a relaxant, in a reasonable time. We also describe the complete production cycle for the generation of large quantities of hyperpolarized xenon from xenon gas by a cryogenic method for use in MRI and material science.
