How this entity was disambiguated
This entity first appeared as the object of triple T7021971 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Bragg's law
Bragg's law is a fundamental equation in X-ray crystallography that relates the angles at which X-rays are diffracted by crystal lattice planes to the spacing between those planes.
-
B.
Debye–Scherrer method
The Debye–Scherrer method is an X-ray powder diffraction technique used to determine the crystal structure and lattice parameters of polycrystalline materials.
-
C.
Neumann’s principle in crystallography
Neumann’s principle in crystallography is a fundamental rule stating that the symmetry elements of any physical property of a crystal must include the symmetry elements of the crystal’s point group.
-
D.
Kikuchi lines in electron diffraction
Kikuchi lines in electron diffraction are characteristic pairs of diffuse, intersecting bands in electron diffraction patterns that arise from inelastic and subsequent coherent scattering in crystals, and are widely used for precise crystallographic orientation analysis.
-
E.
Bragg
Bragg is a surname most famously associated with physicists William Henry Bragg and his son Lawrence Bragg, pioneers of X-ray crystallography and Nobel Prize laureates.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
