High symmetry indexing example

Bragg angles are listed for the loeation of the Kui component in the doublet, 1.540593 A. 

After combining Eqs. 5.4 and 5.3 we get the following equation relating Bragg angles, lattice parameters and Miller indices  

A more precise definition of h aj, k ua and l ta can be given in terms of the maximum reciprocal lattice vector length, which is d, max 2/X.

The number of multipole parameters is reduced by the requirements of symmetry. As discussed in chapter 3, the only allowed multipolar functions are those having the symmetry of the site, which are invariant under the local symmetry operations. For example, only / = even multipoles can have nonzero populations on a centrosymmetric site, while for sites with axial symmetry the dipoles must be oriented along the symmetry axis. For a highly symmetric site having 6 mm symmetry, the lowest allowed / 0 is d66+ all lower multipoles being forbidden by the symmetry. The index-picking rules listed in appendix D give the information required for selection of the allowed parameters.
