Bragg’s diffraction condition

Between the direct methods, the X-ray diffrac-tometric sin v /s-method is the most important one (Macherauch and Muller 1961). With this method, according to Bragg s diffraction condition, net plane distances dhki are measured, i.e., existing strains are measured directly. As strain of a specimen is direction dependent, it is necessary to incline the specimen around the angle (Fig. 6). 

Bragg s Law [142], Like other diffraction phenomena in periodic structures, electron diffraction can be described in either direct or reciprocal space. Bragg s diffraction condition describes diffraction in direct space. A diffracted beam will be formed whenever the incident beam encloses with the set of lattice planes an angle Bh. such that the path difference sin ( h between waves diffracted by successive lattice planes is an integer n of wavelengths 2 of the radiation used ...
