From equations (7) and (14), the Debye–Waller factor T ( q → → ) contributes to the observed intensity of a diffraction experiment. And based on (16), we see that our anisotropic displacement factor U is responsible for determining T ( q → → ) . Additionally, (15) shows that U may be directly related to the probability density function p for a nuclear displacement u → → from the mean position. As a result, it's possible to conduct a scattering experiment on a crystal, fit the resulting spectrum for the various atomic U values, and derive each atom's tendency for nuclear displacement from p .
