(a) Water reflectivity collected at 25 keV within 60 min (circles). The continuous black line shows the ideal Fresnel reflectivity for water and the blue line shows the Fresnel reflectivity with a roughness of 3.18 ± 0.03 Å. The inset shows log(R/RF) over qz 2. (b) Reflectivity close to the critical angle. |
