Fig. 4: Time-delayed Sc K-shell fluorescence recorded by detectors Du and Dd as a function of incoming X-ray photon energy (expressed as the difference of the incident energy Ei and the resonance energy E0).
From: Resonant X-ray excitation of the nuclear clock isomer 45Sc
The solid black line shows the resonance line obtained from the data evaluation (see section ‘Data analysis’). The coloured dots show exemplary binned data, with different incident energy bin sizes and shifts of the bin grid. The spectral width of 1.32(12) eV reflects the spectral width of the incoming XFEL radiation.
