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

TLDR

The review covers K, L, and higher shell x‑ray fluorescence yield data from 1978–1993, building on earlier compilations by Bambynek et al., (1972), and Krause (1979), and lists selected well‑characterized measurements from that period. The study compares measured and theoretical fluorescence yields ωk, ω̄L, and ω̄M and discusses their application to calculating x‑ray energy‑absorption coefficients. The authors provide an annotated bibliography of fluorescence yield measurements (1978–1993), fit selected values to Z‑polynomial models via least squares, and compare these fits with theoretical predictions and earlier compilations. The paper presents fitted values of ωK, ω̄L, and ω̄M using standard empirical parametric formulations and Z‑polynomial least‑squares fits, and compares them with theoretical predictions and earlier compilations.

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.
