Figure 2
Experimental reflectivity (circles) of the Ni-coated mirror versus the grazing angle in the soft X-ray region at photon energies E = 140 eV (1), 450 eV (2), 650 eV (3) and 900 eV (4). Dashed curves are the result of calculation in frames of the four-layer model with the use of the concentration profiles shown in Fig. 5(a)[link]. Solid curves were obtained after numerical refinement and were calculated with the use of the depth-distribution of the chemical elements concentration shown in Fig. 5(b)[link]. Curve 4 is shifted down by a factor of 100 for clarity.
