• More than 3300 experimental values of K-shell fluorescence cross sections (σ K β 1 , 3 , σ K β 2 , 4 , σ K α 1 , σ K α 2 , σ K β 1 , σ K β 2 , σ K β ′ 1 , σ K β ′ 2 , σ K α , σ K β and σ K t o t ) are summarized in 11 tables. • The data encompasses elements with atomic number in the range 16 ≤ Z ≤ 92 by photo-ionization in multiple excitation energy ranging from 5.46 to 661.6 keV. • The experimental values reported in 96 papers by numerous researches were published between 1985 and 2023. • A critical examination of these data was performed. The main purpose of this paper is to collect from various sources over 3300 experimental values of K-shell fluorescence cross sections (σ K β 1 , 3 , σ K β 2 , 4 , σ K α 1 , σ K α 2 , σ K β 1 , σ K β 2 , σ K β ′ 1 , σ K β ′ 2 , σ K α , σ K β and σ K t o t ) of elements with atomic number in the range 16 ≤ Z ≤ 92 by photo-ionization in multiple excitation energy ranging from 5.46 to 661.6 keV, which are presented in a form of 11 tables. The experimental values reported in 96 papers by numerous researches were published between 1985 and 2023. Therefore, by considering in the same tables a calculation of weighted average fluorescence cross section (σ K j) W , with (j = β 1 , 3 , β 2 , 4 , α 1 , α 2 , β 1 , β 2 , β ′ 1 , β ′ 2 , α , β and tot) for each element; a full study of these data is carried out. However, dividing the measured values (σ K j) E x p by the weighted average (σ K j) W , a new weighted means ratio S W = (σ K j) E x p / (σ K j) W are also studied. [ABSTRACT FROM AUTHOR]

In this study, a comprehensive dataset of X-ray emission intensity ratios has been compiled, including I L β / I L α , I L γ / I L α , I Ll / I L α , I L γ / I L β , I Ll / I L γ , I Ll / I L β , I L γ 5 / I L α , I L γ 44 ′ / I L α , I L η / I L α , and I L γ 1 / I L α , extracted from literature spanning the years 1971 to 2023, and encompassing 83 research papers. Over this timeframe, a total of 2600 values were collected, comprising some 678 values for I L β / I L α , 696 values for I L γ / I L α , 617 values for I Ll / I L α , along with 132, 132, 89, 60, 70, 71, and 55 data points for I L γ / I L β , I Ll / I L γ , I Ll / I L β , I L γ 5 / I L α , I L γ 44 ′ / I L α , I L η / I L α , and I L γ 1 / I L α , respectively. The reported values are presented with precision up to three to four decimal places, accompanied by their associated uncertainties. Additionally, the tables include calculated weighted averages (I L i / I L j ) W , uncertainty values (ε I S D , ε E S D), combined standard deviations (z I S D , z E S D), and average z-scores ( z ¯ I S D , z ¯ E S D ) for these intensity ratios. The data encompasses elements ranging from 39 Y to 94 Pu when excited by photon bombardment. The assessment of how these experimental data values are distributed according to atomic number indicates extensive coverage across most elements. However, a few isolated instances were identified where either no data or fewer than two data values were available. [ABSTRACT FROM AUTHOR]
