| Abstract: | We present detailed calculations of the diffraction pattern of a powder of bundles of C60 peapods. The influence of all pertinent structural parameters of the bundles on the diffraction diagram is discussed, which should lead to a better interpretation of X-ray and neutron diffraction diagrams. We illustrate our formalism for X-ray scattering experiments performed on peapod samples synthesized from 2 different technics, which present different structural parameters. We propose and test different criteria to solve the difficult problem of the filling rate determination.Received: 19 May 2004, Published online: 26 November 2004PACS: 61.46. + w Nanoscale materials: clusters, nanoparticles, nanotubes, and nanocrystals - 61.10.Dp Theories of diffraction and scattering - 61.10.Nz X-ray diffraction |
