Figure 6
Contrast variation (a) in neutron diffraction using H2O/D2O mixtures (Worcester, 1975) and (b) from anomalous X-ray diffraction. The experimental data are given by the following symbols: circles for the reflection (h,k) = (1,1), squares for (h,k) = (2,0) and triangles for (h,k) = (2,1). Straight lines fit the neutron scattering data. The variation of the X-ray scattering intensity follows the dispersion of f′. |
