Elements of X-ray Diffraction
Prentice Hall, 2001 - Technology & Engineering - 664 pages
Intended to acquaint the reader with the theory of x-ray diffraction, the experimental methods involved, and the main applications. The book is a collection of principles and methods stressing X-ray diffraction rather than metallurgy. KEY TOPICS: The book is written entirely in terms of the Bragg law and can be read without any knowledge of the reciprocal lattice. It is divided into three main parts--Fundamentals; experimental methods; and applications. MARKET: Designed for beginners, not as a reference tool for the advanced reader.

4-3 SCATTERING BY AN ATOM When an x - ray beam encounters an atom ,
each electron in it scatters part of the radiation coherently in ... The net effect is
that coherent scattering by an atom is due only to the electrons contained in that
20-2c illustrates schematically the trajectory of electrons traveling parallel to but
off of the optic axis . Actually , the electron spirals toward the optic axis and then
crosses it with r steadily decreasing and then increasing again ; therefore , the ...
At an operating voltage of 100 kV , the electron wavelength is about 0.04 Å , or
considerably shorter than the wavelength of x - rays used in diffraction . Electron
diffraction differs from x - ray diffraction in the following ways : 1 . Electrons
