We present a systematic, multiparameter study of Rb/(129)Xe spin-exchange optical pumping (SEOP) in the regimes high xenon pressure and photon flux using 3D-printed, clinical-scale stopped-flow hyperpolarizer. In situ NMR detection was used to dynamics (129)Xe polarization as function SEOP-cell operating temperature, flux, partial maximize (PXe). PXe values 95 ± 9%, 73 4%, 60 2%, 41 1%, 31 1% at 275, 515, 1000, 1500, 2000 Torr Xe were achieved. These separately validated by ejecting...
We report on hyperpolarization of quadrupolar (I=3/2) 131Xe via spin-exchange optical pumping. Observations the polarization dynamics show that effective alkali-metal/131Xe cross-sections are large enough to compete with spin relaxation. up 7.6 p/m 1.5 percent was achieved in ca. 8.5EE20 spins--a 100-fold improvement total angular momentum--enabling applications including measurement spin-dependent neutron-131Xe s-wave scattering and sensitive searches for time-reversal violation...
