Table 1.11.2.1 | top | pdf |
The indices $[\ell]$ of the screw-axis/glide-plane forbidden reflections ( $[n = 0, \pm 1, \pm 2,\ldots]$ ) and independent components of their tensorial structure factors $[F^{{\bf H}}_{jk}]$

Other components: $[F^{{\bf H}}_{yy}=-F^{{\bf H}}_{xx}]$ , $[F^{{\bf H}}_{zz}=0]$ , $[F^{{\bf H}}_{jk}=F^{{\bf H}}_{kj}]$ . The direction of the z axis is selected along the corresponding screw axes. The last column lists different types of polarization properties defined in Section 1.11.3.
