High volume hyperpolarizer for spin-polarized noble gas

A method for hyperpolarizing 129 Xe, comprising: hyperpolarizing 129 Xe in a target gas, characterised in that said gas comprises: a) a fluorescence-quenching gas, for quenching alkali-metal fluorescence, b) a buffer gas, for pressure-broadening the optical absorption spectrum of alkali metal atoms,...

Summary:A method for hyperpolarizing 129 Xe, comprising: hyperpolarizing 129 Xe in a target gas, characterised in that said gas comprises: a) a fluorescence-quenching gas, for quenching alkali-metal fluorescence, b) a buffer gas, for pressure-broadening the optical absorption spectrum of alkali metal atoms, and c) xenon comprising 129 Xe in at least isotopic abundance; under conditions sufficient to induce hyperpolarization of said 129 Xe by spin exchange with alkali metal atoms, thereby providing hyperpolarized 129 Xe.
