The elastic pattern typically consists of sharp Bragg reflections if the sample is crystalline.

Plastic crystals possess strong long range order and therefore show sharp Bragg reflections.

The structural coloration is created by Bragg reflection from helicoidally stacked cellulose microfibrils.

For Bragg reflections in neutron and X-ray diffraction, the momentum difference between incoming and diffracted X-rays of a crystal is a reciprocal lattice vector.

An X-ray interference field created by Bragg reflection provides the length scale against which atomic distances can be measured.

A Bragg reflection is the splitting of the dispersion surface at the border of the Brillouin zone in reciprocal space.

Therefore Bragg reflections are only coming from the surface structure.

The intensities of the Bragg reflections will therefore change.

In the case of long range magnetic order, this leads to the appearance of new Bragg reflections.

Spiral coils, formed of helicoidally stacked cellulose microfibrils, create Bragg reflection in the "marble berries" of the African herb Pollia condensata.
