In this paper, we explor e the effect of density on the structure fo rmation and the electromagn etic wave (EMw) elastic scattering on quantum plasmas, using the generalized quantum hydrodynam ic model valid for a wide range of the plasma density and relativistic degeneracy. It is found that the electron quantum diffract ion effect caused by the Bohm pot ential has a fundamental effect on the ion correlations in a degenerate electron fluid and cry stallization in quantum plasmas in the soliddensity regime and beyond. The ion correlations and structure formati on are shown to be fundamentally affected by the plasma density and the relativ istic degeneracy parameters. Moreover, distinct behavior is shown to exist bet ween the non-relativi stic and relativistic matter density regimes, regarding the norm alized EMw elastic scatterin g cross-sections. It is theoretically discovere d that the maximal Thomso n sca ttering coincides wit h the average densi ty of a typ ical white dw arf cor responding to the soft X-ray wavelength reg ime. Current research can be very useful in plasma optical diagnostic methods for a wide range of electron number- density from warm dense matter and inertial confin ement fusion to the astrophysica l compact objects.
