Electron Diffraction Electron Diffraction
This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...
متن کاملUltrafast electron diffraction using an ultracold source
The study of structural dynamics of complex macromolecular crystals using electrons requires bunches of sufficient coherence and charge. We present diffraction patterns from graphite, obtained with bunches from an ultracold electron source, based on femtosecond near-threshold photoionization of a laser-cooled atomic gas. By varying the photoionization wavelength, we change the effective source ...
متن کاملElectron Diffraction
In this equation, h is Planck’s constant and E = p/(2m) is the kinetic energy of the particle in the non-relativistic regime. The wave aspect of particles was demonstrated first by an experiment on electron diffraction performed by C. H. Davisson and L. H. Germer. For his hypothesis on the wave nature of particles de Broglie was awarded the Nobel Prize in Physics in 1929, and Davisson and Germe...

his excellent Life of Harvey in the revised bibliography, particularly as it illuminates the notes of provenance. Both Severino and Peiresc, who appear in the Appendix, seem to have owned and annotated copies of De motu cordis. Keynes's Life updates and sometimes contradicts previous statements in the bibliography, so that rewriting the bibliographical prefaces (a task shared by both editors, i...
متن کاملOn the alignment for precession electron diffraction.
Precession electron diffraction has seen a fast increase in its adoption as a technique for solving crystallographic structures as well as an alternative to conventional selected-area and converged-beam diffraction methods. One of the key issues of precession is the pivot point alignment, as a stationary apparent beam does not guarantee a fixed pivot point. A large precession tilt angle, along ...
