Fig. 4: Resonant Auger electron spectra.
From: Observation of molecular resonant double-core excitation driven by intense X-ray pulses
a, b Experimental electron kinetic energy vs. photon energy -maps at low and high X-ray intensities, respectively. The kinetic energy resolution is ~0.6 eV. c Line spectra from the low intensity (“E”) and high intensity (“F”) measurements, extracted along the correspondingly marked areas in the 2D-maps (a, b) above. On the top, the same spectra are also shown with 10× multiplication, offset for clarity. The SCH-P, as well as the DCH-PP and DCH-SP features are marked. d Calculated SCH and ts-DCH decay spectra. e Experimental synchrotron radiation X-ray photoelectron spectroscopy (SR XPS) reference data from Ueda et al.31 (1σ−1) and Kempgens et al.42 (1σ−1v−11π*1), plotted in the kinetic energy scale EK = 2hν − EB, and scaled arbitrarily in terms of intensity. The partial electron yields extracted along the marked areas “A” to “D” in (a, b) are plotted in Fig. 3b.
