Figure 6
Normalized contrast I⁺ − I⁻ and the unpolarized I⁺ + I⁻ scattering intensities as a function of the sample thickness. The unpolarized intensity I⁺ + I⁻ is fitted to l exp(−μl) (with fixed μ = 0.032 sheet⁻¹ and only one free parameter: the scaling factor), drawn as the black solid line. The first five data points of the contrast SANS signal (the polarization for the fifth data point is calculated to be P = 74%) are fitted to equation (18
