Atomic scattering factor for compounds

  1. Jun 27, 2013 #1
    Hi there,

    I am trying to calculate diffraction efficiencies of a lattice with the coupled wave theory. As material parameters the programm I got needs the atomic scattering factor f1 and f2. (see http://henke.lbl.gov/optical_constants/asf.html for elements)
    I understood this seems to correlate to the values δ and β in the complex index of refraction for atoms. This seems not to be true for compounds. As there is of course a index of refraction defined for compounds (http://henke.lbl.gov/optical_constants/getdb2.html).

    Is there an equivalent number for the optical properties for composite materials?
