Figure 2
Prompt electronic (a) and delayed nuclear reflectivity (b) curves as well as stroboscopic SMR spectra (c)–(e) of a [natFe/57Fe]10 isotopic multilayer at grazing angles indicated by the arrows. Vertical dotted lines in panels (c)–(e) indicate the centre of the zero and ±1-order stroboscopic bands separated by ∊ ≃ 10.93 mm s−1 for the applied observation window period. |
