X‐ray filter assembly for fluorescence measurements of x‐ray absorption fine structure

Review of Scientific Instruments, 1979
Fluorescence detection, in principle, permits the detection of the extended x-ray absorption fine structure (EXAFS) of more dilute atoms than can be obtained in absorption. To take advantage of this it is necessary, in practice, to eliminate the background that normally accompanies the fluorescence signal.

Relativistic effects in the x-ray-absorption fine structure

Physical Review B, 1994
A relativistic model for the extended x-ray-absorption fine structure, in which the energy loss of the emitted photoelectron is accounted for by using a complex energy-dependent exchange-correlation potential, has been developed. Relativistic curved-wave single-, double-, and triple-scattering formulas for excitation from any core hole have been found.

The Fine Structure of X-ray Absorption Edges

Nature, 1929
IT is well known that the edges of X-ray absorption spectra are very often accompanied by secondary edges on the short wave-length side. For this phenomenon the following explanation has been proposed (D. Coster, Zs. f. Phys., 25, 83; 1924: A. Sommerfeld, “Atombau”, fourth German edition, p. 326 ; 1924).

Extended X-Ray Absorption Fine Structure

1986
Abstract This article provides an introduction to extended x-ray absorption fine structure (EXAFS). It describes the fundamentals of EXAFS with an emphasis on the physical mechanism, the single-scattering approximation, and multiple-scattering effects.

X-ray Absorption Fine Structure Techniques

Particulate Science and Technology, 2010
X-ray absorption fine structure spectroscopy (XAFS) is a unique probe for local atomic and electronic structure of absorbing centers in particulate science, physics, chemistry, and biology. During the past several decades, XAFS has gained dramatic advances in every aspect, including theoretical explanation and experimental applications. In this review,
