(a) The transmission scattering pattern of vanadium along zone axis [110] recorded on a Mar345 image plate. The image was averaged from 61 images by the FIT2D program, and the indexing is based on the bcc lattice. (b) The overlay of the experimentally measured total scattering intensity and calculated intensity along the [110] direction.

(a) Fits of measured intensity of vanadium from to along [110] with four models. (b) The fits of measured intensity of vanadium from to along [110] with four models.

(a) The illustration of how lattice diffraction rods 220 arise from the shape function of the crystal. The thickness of the sample is about 6000 unit cells, and the intensity is normalized per unit cell volume. The inset illustrates the Ewald sphere construction and the intensity distribution of lattice diffraction 220 rods. The represents the deviation of the Laue condition and is called excitation error. The arrows mark the intersections of the Ewald sphere corresponding to 115.3 keV, 57.7 keV with the diffraction rods. (b) The fitted phonon dispersion curves of vanadium along . The lines are the fitting results from our experiments, and the diamond, square, and triangle symbols are experimental data (see Ref. 17). The diamond symbols represent the longitudinal modes while the square symbols correspond to transverse modes. (c) The fitted phonon dispersion of vanadium along . The lines are the fitting results from our experiments, and the diamond, square, and triangle symbols are experimental data (see Ref. 16). The diamond symbols represent the longitudinal modes (L) while the squares are transverse modes (T).
