# Silver behenate

Silver behenate is a widely used calibration sample in X-ray scattering measurements. Its lamellar structure (one-dimensional periodicity) manifests itself as several orders of Bragg peaks in the scattering curve (Bragg rings in the scattering image). The next figure shows a typical scattering image of silver behenate and the scattering curve resulting thereof by azimuthal averaging.

The repeating distance of our silver behenate powder specimen is 5.8402 nm, thus the first order Bragg reflection is found at $2\pi/5.8402$ nm-1 = 1.0759 nm-1.
