When a primary beam of monochromatic x-rays falls on a specimen, the x-rays may be absorbed or scattered. Coherent scattering of x-rays from an ordered arrangement of scattering centers (such as the environment present in crystals) leads to diffraction. The use of x-ray diffraction for characterizing powders is described in the next section. The absorption of x-rays leads to electronically excited atoms (ions) due to the ejection of electrons (i.e., the photoelectric effect) or to the transition of electrons to higher energy levels (Fig. 3.16a). (The ejected electrons, as described later, form the basis for the surface characterization technique of x-ray photoelectron spectroscopy.)... [Pg.160]
