    58Calculates the scattering from a **face-centered cubic lattice** with 
    69paracrystalline distortion. Thermal vibrations are considered to be 
    710negligible, and the size of the paracrystal is infinitely large. 
    811Paracrystalline distortion is assumed to be isotropic and characterized by 
    9 a Gaussian distribution.
