Fremstilling af hyperpolariseret xenon ved hjælp af spinudveksling optisk pumpning (Seop) er beskrevet. Denne metode giver et ~ 10.000-ganges forøgelse af den nukleare spin-polarisering af Xe-129 og har anvendelser i kernemagnetisk resonans-spektroskopi og billeddannelse. Eksempler på gasfase-og opløsningstilstand eksperimenter.
