L shell fluorescence yields and coster—kronig transition probabilities for the elements with 25 ⩽ Z ⩽ 96

The values of Li sub-shell fluorescence yields (ωi) and Coster–Kronig transition probabilities (fij) were evaluated using radiative and non-radiative transition rates based on the relativistic Dirac–Hartree–Slater (RDHS) model for all the elements in the atomic number range 25 ⩽ Z ⩽ 96. The values of the Coster–Kronig-corrected fluorescence (vi) and average L shell fluorescence (ϖL) yields were also evaluated and least-squares fitted to obtain the polynomials representing them as a function of atomic number.
