Interactive Tutorial about Diffraction
Interactive example : Scattering from different atoms
It is instructive to plot the respective intensities scattered by
two different atoms into a common picture. This allows you to
quickly achieve an understanding about the different scattering
behavior of the atoms.
The controls on the right allow you to choose two atoms. The
server will then calculate the respective intensities and present
them in a common plot. The image on the left shows the respective
intensities on the correct relative scale. In the right image, the
intensities have been scaled to identical values at the origin of
reciprocal space. This images allows you to focus on the changes
in the shape of the different scattering curves. You can also
select whether to calculate X-ray or neutron intensities. The
calculated range for the scattering intensity h is fixed to
0 to 1 Å-1.
