MS-48: Combination of X-rays and electrons for structure characterization
Invited: Stef Smeets (Netherlands), Tatiana Gorelik (Germany) | ||
Session Abstract | ||
If a single crystal of adequate size and quality is available, single-crystal X-ray diffraction is the method of choice for structure analysis. However, if such crystals are not available, powder X-ray diffraction and electron crystallography provide a viable alternative. Structure analysis from X-ray powder diffraction data are hampered by reflection overlap, but the diffraction process is kinematic, so the reflection intensities are easily interpreted. Electron diffraction data do not suffer from reflection overlap, but the diffraction process is dynamical, and this makes the intensities more difficult to interpret directly. By combining these two techniques, the structures of materials that are difficult to elucidate with either technique alone become accessible.
