Fig. (14) (a) The overall response function of the experiment [122] obtained from the measured KL₂L₃ Auger line by means of Eq. (13). The low-energy tail extends up to –1000 eV. The total intensity is normalized to one. (b) The calculated shake up/off spectrum convoluted with a Lorentzian corresponding to the natural line width Γ = 11.43 eV. The peak at the energy loss of 0 eV corresponds to the no-energy-loss component whose probability is 80%.
