等离子体不透明度在辐射输运和辐射流体力学研究中具有重要的应用，在实际应用中，这些参数主要依赖于理论研究获得，实验提供了对理论计算精度的检验。在细致能级模型的理论框架下，对铝、铁和金等离子体的辐射不透明度进行了系统的理论研究，建立了在密度0.001-0.1 g/cm3和温度1-300 eV范围内光谱分辨的辐射不透明度和Rosseland和Planck平均不透明度数据库。不透明度的理论研究涉及到特定等离子体条件下的大量量子态，在复杂的金等离子体条件下，量子态的数目可能以亿计，甚至达到万亿乃至更大，因而其精确的研究显然具有很大的挑战性。对于高Z的金等离子体，公开发表的不透明度数据非常少，本工作提供的数据库为高Z不透明度研究提供了参考。对中低Z的铝和铁等离子体，本课题组以前公开发表的工作很好地解释了实验结果，表明了理论方法的可靠性。本文与国际上ATOMIC程序得到的理论结果进行了比较，分析了两种方法得到结果的异同，大部分等离子体条件下，两者符合较好，对于有差异的部分，指出了差异的物理根源。Radiative opacity plays an important role in investigations on radiative transfer, radiation hydrodynamics and other related disciplines. In practical applications, these data are mainly obtained by theoretical calculations. The accuracy of the theories is checked by limited experiments. In the theoretical frame of detailed level accounting method, a systematic investigation is carried on spectrally resolved and Rosseland and Planck mean opacities of aluminum, iron, and gold plasmas under conditions in a density range of 0.001-0.1 g/cm3 and a temperature range of 1-300 eV. A data base is built based on these theoretical opacities. A huge number of quantum states are involved in the calculation of opacity, especially for high-Z gold plasmas. This poses a great challenge to obtain accurate opacity of gold plasmas. For such high-Z plasmas, there is a necessity to develop other codes such as unresolved transition array or even average atom model to fast obtain the opacity. Accurate opacity data are lacking very much for such high-Z plasmas and the data presented in this library represent an important reference for other less detailed opacity codes.
For aluminum and iron plasmas, the opacities are compared with one of the most accurate code ATOMIC. It is found that a good agreement is obtained for most cases of plasma conditions. Yet discrepancies are still found at a few cases of plasma densities and temperatures, as demonstrated in Fig. S1 where there is an excellent agreement between the bound-free opacity obtained by our code and the ATOMIC. At photon energy around 850 eV, however, some strong lines of aluminum plasmas are found to be missing in Al plasmas in other codes, which will affect the radiative transfer in x-ray region. In our code, we avoid such issues by including all possible line absorption and photoionization channels. The present dataset should be helpful for the study of inertial confinement fusion, plasma physics and astrophysics.-
