... the glide-plane forbidden reflections, there may, for instance, exist a glide plane perpendicular to the axis, i.e. any point is ... vanishes. This is the well known conventional extinction rule for a glide plane, see International Tables for Crystallography Volume A (Hahn, 2005). If, however, is a tensor, the ...

Tensorial structure factors and forbidden reflections
Dmitrienko, V. E., Kirfel, A. and Ovchinnikova, E. N.  International Tables for Crystallography (2013). Vol. D, Section 1.11.2.2, pp. 270-271 [ doi:10.1107/97809553602060000910 ]

As a result, forbidden reflections can in fact be excited just due ... be deduced from equation (1.11.2.1). The structure factor of a reflection with reciprocal-lattice vector is proportional to the ...
