This is because orientational averaging causes the three-dimensional reciprocal space that is studied in single crystal diffraction to be projected onto a single dimension.
22.
The potentials of the atomic cores can be decomposed into Fourier components to meet the requirements of a description in terms of reciprocal space parameters.
23.
The scattering rate gives the probability per unit time to scatter from a state " k " to any other state in the reciprocal space.
24.
To explicitly calculate the partition function using the segment density one has to switch to reciprocal space, change variables and only then execute the integration.
25.
The rotation axis should be changed at least once, to avoid developing a " blind spot " in reciprocal space close to the rotation axis.
26.
The algorithms make use of fast Fourier transforms ( FFT ), often employing gaussian shaped soft-edged masks in reciprocal space to suppress certain frequency ranges.
27.
Effectively, the objective lens in a typical microscope is replaced with software to convert from the reciprocal space diffraction pattern into a real space image.
28.
Applying standard diffraction techniques to crystal powders or polycrystals is tantamount to collapsing the 3D reciprocal space, as obtained via single-crystal diffraction, onto a 1D axis.
29.
In type II the conduction and valence subbands are staggered in both real and reciprocal space, so that electrons and holes are confined in different layers.
30.
ECHIDNA allows for structure determinations, texture measurements and reciprocal space mapping of single crystals in most different sample environments serving the physics, chemistry, materials, minerals and earth-science communities.
