(a) HERFD contour plot of the ratio FF/I1 of the average fluorescent count, FF, to upstream ion chamber count, I1, of the crystal analysers for the Mn metal foil, versus incident energy and emission energy. The horizontal line at 5898.6 eV emission energy is a HERFD-XAS scan at the peak of the Kα1 signal; the horizontal line at 5887.4 eV emission energy is a HERFD-XAS scan at the peak of the Kα2 signal (Nguyen et al., 2021BB44); the potential RIXS pre-edge resonance signal is weak for Mn metal and restricted to below an incident energy of 6540 eV. The vertical line is a HERFD-XES characteristic spectrum. (b) Integration of the ratio of fluorescent counts to upstream ion chamber counts for Mn foil at incident energies from 6568.50 eV to 6570 eV, normalized to the maximum value at the Kα1 peak. The maximum integrated fluorescent to upstream ion chamber count ratio is 0.819 at the Kα1 peak.
