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

Abstract

Abstract 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 ( ω L1 , ω L2 and ω L3 ) taken from different sources. First, a critical examination of these data using the weighted average values ω Li - W was presented. Then, an interpolation using the famous analytical function ( ω Li - W / ( 1 − ω Li - W ) ) 1 / 4 vs the atomic number Z was proformed to deduce a new empirical Li subshell fluorescence yields for elements in the range 40≤Z≤96 for ω L1 and ω L2 and 23≤Z≤96 for ω L3 . At last, our calculated empirical Li subshell fluorescence yields have been compared with other theoretical and empirical values reported in the literature.
