L-1, L-2, and L-3 subshell fluorescence yields: Updated database and new empirical values

摘要

In this paper, a summary of experimental data published in the period of time between 1955 to february-2016 was presented in a tabular form for L, subshell fluorescence yields (omega(L1), omega(L2) and omega(L3)) taken from different sources. First, a critical examination of these data using the weighted average values omega(Li-W) was presented. Then, an interpolation using the famous analytical function (omega(Li-W)/(1-omega(Li-W)))(1/4) the atomic number Z was proformed to deduce a new empirical L-i subshell fluorescence yields for elements in the range 40 <= Z <= 96 for omega(L1) and omega(L2) and 23 <= Z <= 96 omega(L3). At last, our calculated empirical L-i subshell fluorescence yields have been compared with other theoretical and empirical values reported in the literature. (C) 2016 Elsevier Ltd.
