Structure factor amplitudes from electron diffraction data are far less reliable than their counterparts from X-ray single-crystal and powder diffraction data.

As a hybrid technique, GISAXS combines concepts from transmission SAXS and from GID . From SAXS it uses the form factors and structure factors.
23.
By subverting the principles of Byzantine diplomacy and political culture, Symeon turned his own kingdom into a society-structuring factor in the nomadic world.
24.
In order to determine a crystal structure, it is necessary to know the crystallographic structure factors, but not to know the electron wave phases.
25.
Fortunately, electron microscopes can resolve atomic structure in real space and the crystallographic structure factor phase information can be experimentally determined from an images Fourier transform.
26.
Where " F " is the so-called structure factor and the sum extends over all the reflections measured and their calculated counterparts respectively.
27.
Where F _ { r _ i, k } is the complex structure Factor for image k for a pixel r _ i at radius R.
28.
One can determine g ( r ) indirectly ( via its relation with the structure factor S ( q ) ) using neutron scattering or x-ray scattering data.
29.
The structure factor is then simply the squared modulus of the Fourier transform of the lattice, and shows the directions in which scattering can have non-zero intensity.

In an illustration, the structure factor for a hard-sphere fluid is shown in the Figure, for volume fractions \ Phi from 1 % to 40 %.
