测量铝的不透明度在一个很好的特点，热，致密，激光产生的等离子体的报告。在激光加热的平板等离子体中，测量了Al XII ~ Al VIII的1 ~ 2跃迁对X射线的吸收，测量的温度和密度分别为58 ± 4 eV和0.020 ± 0.007gcm ~（-3）。对温度和密度分别进行了测量。等离子体中的条件被确定为是可再现的，空间均匀的，并在几乎完全的局部热力学平衡。的吸收光谱和温度密度数据提供了一个改进的手段进行比较，详细的原子物理和不透明度的计算。
Measurements of the opacity of aluminum in a well characterized, hot, dense, laser produced plasma are reported. Measurements of the absorption of X-rays by 1 to 2 transitions in Al XII through Al VIII have been made in a laser-heated slab plasma at the measured temperature and density of 58 ± 4 eV and 0.020 ± 0.007 g cm-3. Separate measurements of the temperature and density were made. The conditions in the plasma were determined to be reproducible, spatially uniform, and in nearly complete local thermodynamic equilibrium. The absorption spectra and the temperature-density data obtained provide an improved means for comparison with detailed atomic physics and opacity calculations.
