报道了在波长λ = 532 nm和λ = 694 nm处冲击压缩的稠密氙等离子体的光学反射率测量的新结果。对密度ρ = 0.27-3.84 g cm-3、压力P = 1.6-17 GPa的非理想等离子体（Γ = 0.87-2.0）进行了研究。所获得的高光学反射率值是金属流体的特征，并且是在冲击氙中的导电状态的证据。在不同波长下的反射率测量提供了有关冲击波阵面密度分布的信息。
New results on optical reflectance measurements of shock-compressed dense xenon plasma at wavelengths λ = 532 nm and λ = 694 nm are reported. The investigations have been performed for nonideal plasma (Γ = 0.87–2.0) at densities ρ = 0.27–3.84 g cm−3 and pressures P = 1.6–17 GPa. The obtained high optical reflectance values are characteristic of a metallic fluid and are evidence for a conducting state in the shocked xenon. Reflectance measurements at different wavelengths provide information about the density profile of the shock wave front.
