Atomic L-Shell Coster-Kronig, Auger, and Radiative Rates and Flourescence Yields for Na-Th

Abstract

Calculated Auger, Coster-Kronig, and radiative transition rates are used to compute atomic L-shell Coster-Kronig and fluorescence yields. The results are compared with other calculations, experimental yield determinations, and radiative half-width measurements.

A characteristic fluorescence correction factor for use in electron probe microanalysis. II. Evaluation of experimental results and comparisons

“…The comparisons concerning the various models of depth distribution functions are depicted in figures [8][9][10][11][12] explicitely, it should be mentioned that in the cases of K-iK and of L-L excitation the situation is very similar to that found for K-L excitation. Figure 15 shows the results obtained from the evaluation of data where the secondary fluorescence intensity exceeds 1% of the total radiation intensity (58 measurements).…”

“…The fluorescence yields for the K-and L-shells and the corresponding Coster-Kronig transition probabilities were taken from Krause [9]. This author presents a complete set of the parameters in question, and moreover Auerhammer et al [10] stated that the values presented by Krause correspond better with experimental data than those of, e.g., McGuire [11] or Chen et al [12]. Problems [13].…”

2p3/2 −13x−1−3x−13d−1 X-ray satellites spectra in the Lα1 region of 4d transition elements

“…The other 2p 3/2 -1 -3x -1 transitions are not allowed energetically in these elements. Further, no such Coster Kronig transitions take place in elements [34] with Z = 48 to 73.…”

“…, so calculated, has been multiplied with Coster-Kronig transition probability ′ σ , taken from table of McGuire [34]. It should be noted that the CosterKronig transitions help in forming only 2p 3/2 -1 -3d -1 states, and that too only in the elements 32 up to Z = 47.…”

Progress in the Characterization of Layered Structures by X-Ray Microanalysis

“…It follows that, to a first approximation, the average mass absorption coefficient for the L shell is given by if (03BC/03C1)L1 ~ (03BC/03C1)L03B1 and the La line constitutes the majority of the radiation emitted from subshells other that L3. The fluorescence yields and the Coster-Kronig transition probabilities are taken from tabulations of Bambynek et al [13] of theoretical values due to McGuire [14].…”
