The powder lines diagrams are calculated for electron diffraction, X-Ray diffraction,
neutrons powder lines (Fig. 1). The lines' intensity is always calculated
within the kinematical approximation (by default no Blackman correction for dynamical effect,
see M. Blackman, Proc. Roy. Soc. A173 (1939) 68). The intensity of the lines of electron
powder patterns are given by Vainshtein (see K. Vainshtein, Structure Analysis by Electron
Diffraction, Pergamon Press, 1964).
X-Ray powder lines are calculated for both Debye-Scherrer and Guinier-de Wolff cameras
(Fig. 2). The X-Ray wavelength is selectable from 10 different cathodes,
but the X-Ray dispersion (or anomalous absoprtion) is included only for the Kα1
characteristic emission lines and neutral atoms. The Lorentz and polarization factors are included.
The table is saved as a Mathematica notebook (Fig. 3). The plot label contains
the crystal name and the wavelength of the incident radiation. It should be remarked that at the limit
of very hard X-Rays, the X-Ray powder patterns are very similar to electron diffraction powder patterns
(Figures 4a, 4b).
