L1, L2, and L3 subshell fluorescence yields: Updated database and new empirical values

•The collected Li (i=1, 2, 3) subshell fluorescence yields cover the period 1955 to february-2016.•A critical examination of these data (The Weighted average value) were performed.•The Weighted average value were used to deduce the empirical fluorescence yields.•The obtained results are compared with others works.•Reasonable agreement was typically obtained between our result and other works.

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 Li subshell fluorescence yields (ωL1,ωL2andωL3) taken from different sources. First, a critical examination of these data using the weighted average values  ωLi-WωLi-W was presented. Then, an interpolation using the famous analytical function (ωLi-W/(1−ωLi-W))1/4(ωLi-W/(1−ωLi-W))1/4vs the atomic number Z was proformed to deduce a new empirical Li subshell fluorescence yields for elements in the range 40≤Z≤96 for ωL1and ωL2ωL2 and 23≤Z≤96 for ωL3. At last, our calculated empirical Li subshell fluorescence yields have been compared with other theoretical and empirical values reported in the literature.
