Incoherent elastic neutron scattering from vanadium has been employed to determine the mean-squared displacement ''< u/sup 2/ >/sub T/'' through the Debye-Waller exponent for the temperature range between 4.2 and 296 K. Significant corrections to the scattering data arise from (i) primary scattering due to the cylindrical shape of the …

WebDiffraction, as shown with Bragg’s Law in Fig. 1.1 and developed further in Chap. 5, is a type of cooperative elastic scattering by a group of atoms. Diffraction requires “coherent scattering,” characterized by a precise relationship between the phases of the incident and scattered waves.
