Jr. Bodart et al., RECOVERY OF NUCLEAR MAGNETIZATION UNDER EXTREME INHOMOGENEOUS BROADENING, Physical review. B, Condensed matter, 54(21), 1996, pp. 15291-15298
A quantitative model is presented for the transient recovery of nuclea
r magnetization under conditions where nuclear spin dipolar relaxation
to dilute relaxation centers proceeds without the intermediary of nuc
lear spin diffusion. The model is developed for rigid arrays in three,
two, and one dimensions. Comparison with experimental results yields
measures of effective relaxation rats and relaxation center concentrat
ions.
