    • Higher polarizations have been achieved for this gas mixture in earlier work (ref 15) by using a 60 W laser system. For the relaxation measurements and NMR spectra reported in this work, a 30 W laser system is found to yield sufficiently high signal intensities.

    • Although the data in Table 1 agree qualitatively with earlier work involving similarly treated dehydrated samples ref 16, the values in the current report are systematically lower by about 30, The exact cause of this variation is not investigated, but a probable explanation is a difference in the average bead surface area in the two studies. The glass beads are selected for their ability to undergo surface modifying reactions and not bead-to-bead uniformity in size and shape. The beads are described as 1 mm diameter spheres; however, visual inspection reveals a distribution in the size, shape, and surface features such as corrugation and cracks
