Coherent X-ray diffraction calculations¶

Overview of Usage¶

Here is a description probably with examples cchange

class CoherentXray.CoherentXrayDiffraction(g=None)¶

FullCorrFuncfCoherentXrayScattering(state, gridShape)¶

Returns the intensity of scattered light as a function of: reciprocal lattice vector without making symmetry assumptions

$I(q) = \frac{1}{V} \widetilde{e^{2 \pi i g*u(x)}} \widetilde{e^{2 \pi i g*u(x)}}^{*}$

SecondOrderCorrFuncfCoherentXrayScattering(state, gridShape)¶

Returns the intensity of scattered light as a function

of the reciprocal lattice vector q

$I(q) = \frac{1}{V} \tilde{f}(q) \tilde{f}(-q)$

where

$f(x) = e^{2 \pi i g*u(x)}$

Assume that there is a cubic symmetry, so that g = (h/a, k/a, l/a) (set a=1)
