Measurement of magnetic dipole moments ofXem129andXem131by spin exchange with optically pumped Rb

The magnetic moments of xenon atoms ${(}^{129}$ ${\mathrm{Xe}}^{\mathrm{m}}$ and ${}_{}{}^{131}{}_{}{}^{}\mathrm{Xe}_{}^{\mathrm{m}}{}_{}{}^{}$) have been measured with a high precision nuclear-magnetic-resonance method. The nuclei of gaseous xenon were polarized by spin exchange with optically pumped rubidium and the polarization was measured by gamma-ray anisotropy. The static magnetic field for the nuclear magnetic resonance experiment was stabilized and calibrated by optical pumping magnetometers. The measured magnetic moments are ‖μ(129m)‖=0.891 223(4) ${\mu }_{\mathrm{N}}$ and ‖μ(131>)‖=0.994 048(6) ${\mu }_{\mathrm{N}}$.
