FIGURE 8.

Calculated K(²H) values as a function of z₀ (the distance of the electron spin from the bottom of the layer) for several layer thicknesses, a, and densities, d, (a) for a homogeneous distribution, d = 0.055 n/A³, a = 5 Å (▪), d = 0.045 n/A³, a = 6 Å (•), d = 0.033 n/A³, a = 8 Å (▴), d = 0.025 n/A³, a = 8 Å (▾), d = 0.0125 n/A³, a = 8 Å (♦). (b) For a bimodal distribution with a = 8 Å and d = 0.0125 n/A³ (•), d = 0.025 n/A³ (▴), d = 0.033 n/A³ (▾). Here one of the traces for a homogeneous distribution (d = 0.0125 n/A³, (▪)) is shown for comparison. The vertical lines define the range of the layer for a = 5, 6, and 8 Å and the horizontal lines the experimental K(²H) values of 5DSA (upper) and 7DSA (lower).
