Nanostructural Analysis with Atomic Pair Distribution Function by Neutron Total Scattering

Abstract

A diffraction pattern with wide Q-range is obtained by using intense pulsed neutron beam, resulting in the accurate atomic pair distribution function (atomic correlation function, PDF) after Fourier transformation of the diffraction pattern. The atomic pair distribution function can be used for structural analyses of wide range of materials such as amorphous and disordered crystalline materials without periodicity, in addition to the in-between materials. The recent research examples are shown in conjunction with the relationship between the disordered structure and the physical property.
