Abstract

Abstract: Experimental results for Brewster angle measurements are used to estimate the width of the shock front in xenon. The possible influence of the shock front width on the dense xenon reflectivity is discussed. The calculated values of the Brewster angle are shifted with respect to the experimental values. It may be partially related to the nonzero width of the wave front. The estimated values of the widths are 161, 154, and 145 nm for the wavelengths 1064, 694, and 532 nm respectively. These values are obtained within the framework of the Drude theory of reflection in the optically nonuniform media. The density functional theory (DFT) is applied to calculate values of the dielectric function and refraction. The effect is discussed if the widths found could influence the normal reflectivity obtained in the framework of the DFT.
