Collisional 3He and 129Xe frequency shifts in Rb--noble-gas mixtures
Abstract
The Fermi-contact interaction that characterizes collisional spin exchange of a noble gas with an alkali-metal vapor also gives rise to NMR and EPR frequency shifts of the noble-gas nucleus and the alkali-metal atom, respectively. We have measured the enhancement factor 0 that characterizes these shifts for Rb-129Xe in the high-pressure limit to be 49331, making use of the previously measured value of 0 for Rb-3He. This result allows accurate 129Xe polarimetry with no need to reference a thermal-equilibrium NMR signal.
