Abstract

The analytical methods based on X-ray fluorescence are advantageous for practical applications in a variety of fields including atomic physics, X-ray fluorescence surface chemical analysis and medical research and so the accurate fluorescence yields (ω K ) are required for these applications. In this contribution we report a new parameters for calculation of K-shell fluorescence yields (ω K ) of elements in the range of 11≤Z≤30. The experimental data are interpolated by using the famous analytical function (ωk/(1-ωk))1/q (were q=3, 3.5 and 4) vs Z to deduce the empirical K-shell fluorescence yields. A comparison is made between the results of the procedures followed here and those theoretical and other semi-empirical fluorescence yield values. Reasonable agreement was typically obtained between our result and other works.
