X-ray scattering allows, for example, the ground-state electron density of a crystal, say hexagonal close-packed Be, or a molecular solid, to be extracted. Two routes will be discussed by means of which progress should prove possible on fundamental aspects of density functional theory, given such in

β¦ Synopsis
The current state of atomic resolution X-ray holography is discussed on the basis of theoretical simulations and experimental results. The dependence of the spatial resolution on photon energy and angular scan ranges are studied, and presently-used experimental implementations are described together with the data analysis used. Reconstructions of simulated and experimental holograms are compared for a Cu 3 Au crystal structure. Rigorous experimental realizations of pure direct and reciprocal X-ray holography methods are demonstrated, and future developments and applications of the method are suggested.

The x-ray fluorescence beamline of the Laboratorio Nacional de Luz SΓncrotron (LNLS) is described. The main optical component of the beamline is a silicon (111) channel-cut monochromator, which can tune energies between 3 and 14 keV. A general description of two experimental stations is given. Beam
## Abstract Characteristic Xβray fluorescence is a technique that can be used to establish elemental concentrations for a large number of different chemical elements simultaneously in different locations in cell and tissue samples. Exposing the samples to an Xβray beam is the basis of Xβray fluores
