A Review, Bibliography, and Tabulation of K, L, and Higher Atomic Shell X-Ray Fluorescence Yields

Abstract

The K, L, and higher atomic shell x-ray fluorescence yield measured data, covering the period 1978 to 1993, following the major previous compilations by Bambynek et al. (1972) and Krause (1979), are reviewed. An annotated bibliography of x-ray fluorescence yield measurements, analyses, fits and tables 1978–1993 is presented. Comparisons of the fluorescence yields ωk, ω̄L, and ω̄M, based on measurements, and on theoretical models, are presented. Values of ωK, ω̄L, and ω̄M, fitted to standard empirical parametric formulations, are presented. In addition, selected well-characterized measured ωK, ω̄L, and ω̄M results restricted to the period 1978–1993 are listed. These selected measured values are fitted by least squares to polynomials in Z of the form ∑nanZn and compared with theoretical and with earlier fitted values. A section on application of fluorescence yield data to computations of x-ray energy-absorption coefficients is included.

Ionic depletion at the crystalline Gibbs layer of PEG-capped gold nanoparticle brushes at aqueous surfaces

“…Here, we seek to determine the distribution profiles of the Cs and Au based on GIXFS data. Thus, we choose Cs 2 SO 4 salt to induce surface crystallization, taking advantage of the high fluorescence yield of Cs + [22,23] and absorption cross section [24] (compared with K + ). In addition, Cs fluorescent signals (in the energy range 3.5-6 keV) are at higher energies than those of K and thus less attenuated along the pathway from the fluorescent sources to the detector (through windows).…”

Simulation and visualization of attosecond stimulated x-ray Raman spectroscopy signals in trans-N-methylacetamide at the nitrogen and oxygen K-edges

“…The fluorescence yield for both the oxygen and nitrogen core-holes is below 1%. 43 For soft x-ray core-excitations in the light elements, the frequency difference between the K and L x-ray edges is much larger than between the 2s orbital and the ionization potential. Conservation of energy leads to a dominant Auger shake-off rather than shake-up spectra.…”

Investigation of two heavy element scintillators by Monte-Carlo methods

“…The latter requires as input data, the x-ray energy or spectrum, the phosphor material's chemical composition and some standard reference tabulated data related to the phosphor material's physical parameters [8][9][10][11]. This simulation code was developed by performing an account of the energy deposition, which contributes to light generation, from the x-ray photon interactions in the diagnostic energy range.…”
