The scattering function of a mixture of a nematic liquid crystal and a reticulated polyacrylate (PAXY spectrometer, LLB, CEA Saclay; Gautier et al., 2003) is a Lorentz–Lorentz function A few impurities remained in the sample and worsened the experiment because they are anisotropic and oriented by the mesogenic phase. An anisotropic power law was thus necessary to take into account their contribution. The display of azimuthal averages in four different centrosymmetric sectors is very useful for checking the anisotropy and the fit quality even when the intensity is poor. |
