In situ measurements of lattice constants changes corresponding to different dislocation density ranges in KAP (n, -n) double crystals diffraction
In situ measurements of the relative changes in the lattice constants of KAP corresponding to the different dislocation density ranges has been earried out by means of (n,-n) double crystal diffract)metry. The (n, -n) double crystal reflection of the (001) plane with Cuka radiation shows that the relative change in lattice constants due to dislocations are in the range of 3.8～19.2×10-4nm.
