2. Phonons in icosahedral and cubic Al-Li-Cu
- cyclops.ameslab.gov
- Phonons in icosahedral and cubic Al-Li-Cu.
- We describe the results of inelastic-neutron-scattering measurements on single grains of icosahedral Al-Li-Cu and the related cubic R phase. Measurements along the high-symmetry twofold, threefold, and fivefold axes of the icosahedral phase clearly show the existence of well-defined propagating modes, with isotropic dispersion, near strong Bragg peaks. ... In several cases we are able to identify ``quasi''-Brillouin-zones, with stationary points at the ``special'' high-symmetry points of a simple icosahedral lattice. While the phonon dispersion for transverse and longitudinal acoustic modes along the twofold axis of the cubic R phase is quite similar to that found for the icosahedral phase, differences are found in the higher-energy modes; the behavior of the higher-energy modes of the icosahedral phase is consistent with an enhanced degree of spatial localization for these excitations. ...

- Structure and Stability of the Twofold Surface of Icosahedral Al-Pd-Mn by Low-Energy Electron Diffraction and X-Ray Photoemission Spectroscopy.
- We have used low-energy electron diffraction and x-ray photoemission spectroscopy to investigate the structure of the twofold surface of icosahedral Al-Pd-Mn. ... The first stage was the appearance of a fine-grained surface phase with icosahedral, or near-icosahedral, symmetry. For higher annealing temperatures (above 800 K) a bulk terminated face-centered icosahedral surface was observed. ...

- A comparative study of the plastic behaviour of icosahedral and x-Al-Pd-Mn .
- In the Al-Pd-Mn system, large single crystals of high structural quality can be grown of the icosahedral and the x-phase. The latter is an approximant of the icosahedral phase. Though the structure of x-Al?x2013;Pd?x2013;Mn is periodic, it possesses a local order which is very close to that of the icosahedral phase. In this paper, we present a comparative study of the plastic behaviour of single crystals of the icosahedral and the x-phase. ...

- Automated Software Package for Icosahedral Virus Reconstruction.
- The three-dimensional reconstruction of icosahedral viruses from electron micrograph images has become an important tool for understanding virus structure, function, and pathogenesis. ... Our package combines the analytical capabilities of pre-existing algorithms together with approaches we have developed to produce an interactive working environment which enhances the efficiency and usefulness of this approach to the structural analysis of icosahedral viruses.

- Inelastic-neutron- scattering measurements of phonons in icosahedral Al-Li-Cu.
- Inelastic- neutron-scattering measurements on a single grain of icosahedral Al-Li- Cu are presented. Within experimental error the acoustic-phonon dispersion at small, but finite, q is independent of direction, confirming the isotropic elasticity expected for icosahedral crystals. ...

Spherical viruses have icosahedral symmetry and the motivating application is the parametric representation of spherical viruses for use in inverse problems based on x-ray scattering data and cryoelectron microscopy images. ...
