我们目前的研究结果冲击诱导位移的K光吸收边的铝。时间分辨的X射线光谱测量表明,当压缩到正常密度的1.22倍时,最大红移为1.7eV。结果解释使用流体动力学模拟,其中包括一个新的模型计算K边能量在稠密等离子体
We present results of studies on shock-induced shifts in the K photoabsorption edge of aluminum. Time-resolved X-ray spectroscopic measurements indicated maximum red shifts of ∼7 eV for compressions of ∼2.2 times the normal density. The results are interpreted using hydrodynamic simulations which incorporated a new model for calculating the K-edge energy in a dense plasma
