Typical absorption spectra recorded to evaluate the energy calibration and resolution. (a) Argon resonance absorption spectrum measured at the Ar L2,3-edge. The final-state assignments are labeled. (b) Nitrogen 1s π* resonance absorption spectrum measured at the N K-edge. Its fine structure is due to vibrational levels of the state. Min 1 and Max 3 refer to the intensities used to estimate the resolution without the fitting procedure as explained in the text. (c) Neon 1s–np resonance absorption spectrum measured at the Ne K-edge. |
