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.
