用一种新型的高色散X射线光谱仪记录了激光等离子体发射的莱曼线和氢化铝的谱线。确定了空间分辨发射剖面的位移，并将其与实验的数值模拟所得出的等离子体密度进行了关联。观察到的红移与基于量子力学碰撞理论的等离子体极化漂移的预测是一致的。
The Lyman lines , and of hydrogenic aluminum emitted from a laser-generated plasma were recorded using a novel high-dispersion x-ray spectrometer. The shifts of the spatially resolved emission profiles were identified and correlated with the plasma densities inferred from numerical simulation of the experiment. The red shifts observed are consistent with the predictions of the plasma polarization shift based on the quantum-mechanical impact theory.
