Analytical use of the stereographic Wulff net for single-crystal orientation for 1-, 2- and 3-rotated cuts

Abstract

A useful set of expressions that allow the analytical use of the stereographic Wulff net,e.g.for orientation in the Laue method, for 1-, 2- and 3-rotated cuts of single crystals fastened on a two-axis goniometric holder are derived. Application of the derived expressions in everyday crystallographic practice is illustrated by examples. The results of lattice-parameter measurements, the choice of planes suitable for diffractometric orientation, and the values of their Bragg angles, useful for orientation in the Laue and diffractometric methods, are described for Ca4GdO(BO3)3:Nd and CsLiB6O10single crystals.
