使用 λ = 1.06 μm 激光束在 1.6 – 17 GPa 压力和 30 000 K 左右温度下冲击压缩致密氙等离子体的反射系数的实验结果 [1] 与基于不同动态碰撞频率理论方法的计算结果进行了比较。结果发现,假设空间电子密度分布对应于约2·10-6 m的有限激波波前宽度,可以给出合理的描述。
Experimental results [1] for the reflection coefficient of shock‐compressed dense xenon plasmas at pressures of 1.6 – 17 GPa and temperatures around 30 000 K using a laser beam with λ = 1.06 μm are compared with calculations based on different theoretical approaches to the dynamical collision frequency. It is found that a reasonable description can be given assuming a spatial electron density profile corresponding to a finite width of the shock wave front of about 2 · 10–6 m.
