EnglishMolecular differential cross sections for the coherent scattering of x- rays in polymethyl methacrylate (PMMA) and fat were determined from measured diffraction patterns in the interval χ = 0 to 6.4 nm-1 (χ = [sin(θ/2)]/λ;λ being the incident wavelength having the units of nm and θ the scattering angle). All measurements were performed at a controlled temperature of 23 °C. The final results for PMMA show overall agreement when compared with the data existing in the literature. However, some discrepancies with the results reported by Kosanetzky et al in 1987 are found at the first three maxima. The data for filtered fat material are reported here for the first time. Finally, data sets of molecular form factors for fat and PMMA wore compiled from the smoothed corrected experimental results by assuming these materials to be mono-molecular.
