Figure 3
E-GISRMS spectra from a 100 nm-thick 57Fe non-enriched thin film measured at different incidence angles: (a) θ = 0.16°, (b) θ = 0.20°, (c) θ = 0.23°. Dashed lines are the nuclear resonant energies for Δm = 0 transitions of bulk α-Fe. The solid line is the Lorentzian fit curve. Dotted lines are guides for the eye. The four arrows show the theoretically predicted reflectivity minima and maxima positions for the spectrum of θ = 0.23°. |
