Effect of B-Factor on X-Ray Scattering

The scattering of x-rays by atoms decreases with scattering angle partly because of atomic positional disorder. This Demonstration shows the temperature factor as a function of scattering angle. This reduction in scattering power can be described by the expression , where , the displacement parameter or -factor, reflects the mean displacement of the atoms. This Demonstration shows how the scattering strength falls off with increasing .
