Published in 2017 at "Journal of magnetic resonance"

DOI: 10.1016/j.jmr.2017.04.011

Abstract: Continuous-flow spin-exchange optical pumping (SEOP) continues to serve as the most widespread method of polarizing 129Xe for magnetic resonance experiments. Unfortunately, continuous-flow SEOP still suffers from as-yet unidentified inefficiencies that prevent the production of large… read more here.
