This brief review of hard diffraction is focussed on the theory of the diffractive structure function F 2 . Some aspects of diffractive vector meson production and of diffractive processes in hadron-hadron collisions are also discussed.

Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

Introduction Thermionic cathodes are used in many industrial vacuum electronic applications. Vacuum tubes for high-frequency or high-power applications are one example (e.g., see [1]). The emission properties of thermionic electron sources in vacuum devices are often Bimproved[ by the addition of oxide coatings on the metal cathode surface [2, 3]. The explanation of the improvement is usually b...

Cadmium sulfide uniform fine particles have been synthesized in soft conditions, at room temperature, using cadmium complex compounds and thioacetamide. The microstructure and morphology of cadmium sulfide were characterized by X ray Diffraction, Transmission Electron Microscopy, High Resolution Transmission Electron Microscopy, and Selected Area Electron Diffraction. The optical properties of ...

A new database containing crystallographic and chemical information designed especially for application to electron diffraction search/match and related problems has been developed. The new database was derived from two well-established x-ray diffraction databases, the JCPDS Powder Diffraction File and NBS CRYSTAL DATA, and incorporates 2 years of experience with an earlier version. It contains...

Dislocations are extended defects within crystalline solids that often influence the mechanical, electrical, magnetic and optical properties of the material. Establishing more quantitative relationships between dislocations and material properties relies on effective microscopy or spectroscopy methods that can resolve both dislocation type and position within the solid. Diffraction has historic...

This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...
