摘要
The measured K-shell fluorescence-yield values reported in the literature from 1934 to 2015 (about 737 new measurements) were used to deduce new empirical K-shell fluorescence yields for elements in the atomic range 3 a parts per thousand currency sign Z a parts per thousand currency sign 99. In order to deduce the empirical K-shell fluorescence yield, the experimental data were fitted using the quantity (omega (K) /(1 - omega (K) ))(1/4) with respect to the atomic number Z. The results were compared to other theoretical, semi-empirical and experimental values reported in the literature. Reasonable agreement was obtained between our result and those of other works.
