Voigt-function model in diffraction line-broadening analysis
Diffraction-line broadening routes are briefly reviewed. Both laboratory and synchrotron xray measurements of W and MgO showed that a Voigt function satisfactorily fits the physically broadened line profiles. The consequences of an assumed Voigt-function profile shape for both sizebroadened and strain-broadened profiles (“double-Voigt” method) are studied. It is shown that the relationship betw...
متن کاملNOTES AND CORRESPONDENCE Comments on ‘‘A Common Misunderstanding about the Voigt Line Profile’’
In a recent paper, it was argued that some of the illustrations in popular textbooks comparing the Lorentz and Gaussian profiles with the ‘‘corresponding’’ Voigt profile are incorrect. These ‘‘misunderstandings’’ are shown to be a result of ambiguous specifications of the Voigt profile (i.e., there is no unique corresponding Voigt profile). Additionally, some comments on half-widths, numerics, ...
متن کاملAndreas Voigt and Ordinal Utility , 1886 - 1934
In 1893 Andreas Heinrich Voigt published “Zahl und Mass in der Ökonomik” (“Number and Measurement in Economics,” Zeitschrift für die gesamte Staatswissenschaft), in which he argued that utility admits only an ordinal characterization. This paper compares Voigt’s views on ordinalism with those of his contemporaries, and also discusses Voigt’s impact on later economic thought. F.Y. Edgeworth soon...
متن کاملModelling of Nebular Line Profiles
RESUMEN El resumen será traducido al español por los editores. We present a tool, VELNEB 3D, which can be applied to the results of 3D photoionization codes to generate emission line profiles, position-velocity maps and 3D maps in any emission line by assuming an arbitrary velocity field. We give a few examples, based on our pseudo-3D photoionization code NEBU 3D (Morisset, Stasi´nska & Peña 20...
متن کاملVoigt Airy surface magneto plasmons.
We present a basic theory on Airy surface magneto plasmons (SMPs) at the interface between a dielectric layer and a metal layer (or a doped semiconductor layer) under an external static magnetic field in the Voigt configuration. It is shown that, in the paraxial approximation, the Airy SMPs can propagate along the surface without violating the nondiffracting characteristics, while the ballistic...
