给出了爆炸驱动的稠密氙气等离子体上偏振光反射率的初步实验结果。用波长λ=10 6 4 nm、入射角θ=0~30°的激光对等离子体的偏振反射率特性进行了研究。当密度ρ=2.7g cm−3，压力P=10.5 GPa时，等离子体温度达到T∼3⋅10 4K时，存在强库仑相互作用条件(非理想参数达到Г∼2.0)。通过包含等离子体表面密度分布的Helmholtz方程计算了反射率，并与实验结果进行了比较。
The results of first experiments on reflectivity of polarized light on an explosively driven dense xenon plasma are presented. The study of polarized reflectivity properties of the plasma was accomplished using a laser light of wavelength λ = 1064 nm and at incident angles θ = 0–30°. With density ρ = 2.7 g cm−3, pressure P = 10.5 GPa and temperatures up to T ∼ 3⋅104 K of the investigated plasma, conditions with strong Coulomb interaction (the nonideality parameter up to Г ∼ 2.0) were present. Reflectivities, which were calculated via the Helmholtz equation incorporating a density profile for the plasma surface, are compared to the experimental results.
