What are the informations we can get from critical angle in XRR...
Dear Dr. Ranjan Roy, When X-rays incident at a flat surface at grazing angles of incidence, total reflection will occur at or below a certain angle, qc – The critical angle. In the case of Cu Kα radiation, the critical angle is 0.22° for silicon on a glass plate, 0.42° for nickel, and 0.57° for gold. The angle varies depending upon the electronic density of the material. The higher the electron density ρ(z) of a material, the higher the critical angle. θC ≈ √ ρ I have attached some articles to your concern.

To be more precise, critical angle is proportional to the square root of electronic density.
