| Abstract: | The ultraslow motion of defects in high purity hexagonal H2O ice has been studied by proton dipolarT
1D
measurements in the  strong collision limit, using the Jeener technique. The obtained NMR correlation times  agree rather well with both the Schottky H2O diffusion timest
s= r
2 /6D and the deuteron correlation times in D2O ice, suggesting that Schottky rather than interstitial diffusion dominates spin-lattice relaxation in both H2O and D2O ice.On leave of absence from University of Ljubljana, Institute J. Stefan. |
