11. X-ray diffraction with the Laue method, or electron diffraction in a transmission electron microscope. 12. Those experiments revealed the wave property of electrons and opened up an era of electron diffraction study. 13. The vertical axis is defined as acute angle between Fourier transformed lattice fringes or electron diffraction spots. 14. The structure of acetyl cyanide was determined through the joint use of electron diffraction intensities and rotational constants. 15. Electron diffraction is most frequently used in solid state physics and chemistry to study the crystal structure of solids.16. However, the main limitation of electron diffraction in TEM remains the comparatively high level of user interaction needed. 17. Davisson and Germer published notes of their electron diffraction experiment result in Nature and in Physical Review in 1927. 18. :Precession electron diffraction enables much more direct determination of space group symmetries over other forms of electron diffraction. 19. :Precession electron diffraction enables much more direct determination of space group symmetries over other forms of electron diffraction . 20. He was awarded the Warren Award by the American Crystallographic Association in 2015 for his contributions to electron diffraction .
