| Research Abstract |
Nowadays, wide r-range atomic pair distribution function information can be obtained from high Q-resolution total scattering spectrometer at an intense pulsed neutron source facility. We have studied nanostructure effects on the information. They are particle form factor, particle pair correlation, and small angle scattering effects. As an example, we demonstrate that the calculated particle pair correlation effect for spherical shell dimmer well describes the observed triangular atomic pair distribution function of fullerenes. In addition, we have discovered local Mn_6N octahedral rotation in a giant negative thermal expansion material. These results are presented, e.g., in the 54th condensed-matter physics summer school.
