The influence of preferred orientation on integrated x-ray intensities in powder specimen using energy-dispersive diffraction method is investigated. The theory used is based upon examination of the polar axis density distribution. The measurements were carried out using the Schulz technique added with defocusing correction. Experimental results are given for three aluminium powder specimens.
Rapidly recorded X-ray diffraction powder patterns from some metals and from rock salt have been obtained by using the energy sensitive Si (Li) semiconductor detector with the multichannel pulse height analyser. The measured energy resolution of the detector system was about 210 eV for Cu KCY radiation. A good agreement was obtained between observed and calculated positions and relative intensities of the diffraction lines. 8 . H. Cole, J. Appl. Cryst. 3 , 4 0 5 (1970).

The present summary is a brief survey of the energy dispersive X-ray diffraction (E DX R D) method and an appraisal of the current position. A comprehensive chronological list of annotated references on EDXRD is given, covering the period 1968 to 1978. An index of authors is appended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
