Improved precision and accuracy of electron energy-loss spectroscopy quantification via fine structure fitting with constrained optimization
Daen Jannis, Wouter Van den Broek, Zezhong Zhang +2
By working out the Bethe sum rule, a boundary condition that takes the form of a linear equality is derived for the fine structure observed in ionization edges present in electron…
