The polarization and relaxation rates of metastable Xe129 atoms are measured with magnetic resonance spectroscopy, at both microwave frequencies, where ΔF=1 transitions are induced between the sublevels, and at radiofrequencies, corresponding to ΔF=0 transitions. The nuclear spin polarization of the resonant velocity group is measured to be 22±2%. The relaxation of metastable xenon atoms is dominated by depolarizing collisions with ground-state atoms, with lesser contributions from metastability exchange collisions.
