| Abstract | After cryogenic trapping of hyperpolarized xenon produced by optical pumping, significant increases in the spin-lattice relaxation time (T1) of 129Xe in solid xenon at 4.2 K can be achieved by annealing the solid at an appropriate temperature. Thus, T1 at 4.2 K in a field of 180 G increased from 20.4 to 35 h on warming a sealed sample initially condensed at 77 K in an isopentane bath at 113 K for 10 min. This provides further confirmation that the primary relaxation mechanism for 129Xe at low temperature is cross relaxation to 131Xe and demonstrates that long term storage of hyperpolarized xenon produced using flow polarizers is feasible. |
