Figure 5

The ps- and f-sum rule checks for ELFs, the extinction coefficient, and the imaginary part of the dielectric function of Fe at the 2 keV (blue dashed lines) and 3 keV (red lines) primary energies whose theorical values are marked with red arrows and numbers on the right axes, and the calculated results were marked in the legend as well. (a) The ps-sum rule calculated by Eq. (12); (b) the f-sum rule calculated by Eq. (9); (c) the f-sum rule calculated by Eq. (10); (d) the f-sum rule calculated by Eq. (11).
