| Abstract: | Nuclear-magnetic-resonance (NMR) measurement of laser-polarized gaseous129Xe produced by spin-exchange optical pumping with a narrow-linewidth laser at a high magnetic field of 4.7 T is reported. The samples are contained in the glass tubes. The nuclear spin polarization of the laserpolarized129Xe is 3.9%, and this corresponds to an enhancement of 9· 103 compared to the equilibrium value at 311 K and at the same magnetic field. The laser-enhanced129Xe NMR signals can be used in MR imaging. |
