Weiss Zone Law

Weiss zone law states that each hkl reflection must lie in the [UVW] zone:
        hU + kV + lW= 0 ------------------------- [4786]

Note that the Weiss zone law only holds for diffraction into the 0th layer of the reciprocal lattice (zero-order Laue zone, ZOLZ)

Figure 4786 shows ZOLZ, FOLZ (first order Laue zones) and SOLZ (second order Laue zones).

Higher Order Laue Zones HOLZ Low order First LOLZ FOLZ
