Data base for opacity of alumnium, iron and gold plasmas

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. 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. 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 reasonable agreement is obtained for most cases of plasma conditions. The present data base should be helpful for study of inertial confinement fusion, plasma physics and astrophysics.In this dataset, spectrally resolved and Rosseland and Planck mean opacities of aluminum, iron, and gold plasmas are given plasmas under plasma conditions in a density range of 0.001-0.1 g/cm3 and a temperature range of 1-300 eV. The data are given in three separate directories of Al, Fe, and Au, which store the respective opacities of these three elements. In each directory, there are five directories under the names of 0.001gcc, 0.005gcc, 0.01gcc, 0.05gcc, and 0.1gcc, which correspond the plasma densities of 0.001, 0.005, 0.01, 0.05, and 0.1 g/cm3. In each directory, there are ten files which are named XX.YZ, where XX refers to Al, Fe, or Au, and Y can be any one of c (corresponds to a density of 0.001 g/cm3), d (corresponds to a density of 0.005 g/cm3), e (corresponds to a density of 0.01 g/cm3), f (corresponds to a density of 0.05 g/cm3), or g (corresponds to a density of 0.1 g/cm3), and Z can be any one of a (corresponds to a plasma temperature of 2 eV), b (corresponds to a plasma temperature of 5 eV), c (corresponds to a plasma temperature of 10 eV), d (corresponds to a plasma temperature of 20 eV), e (corresponds to a plasma temperature of 50 eV), f (corresponds to a plasma temperature of 100 eV), g (corresponds to a plasma temperature of 150 eV), h (corresponds to a plasma temperature of 200 eV), i (corresponds to a plasma temperature of 250 eV), and j (corresponds to a plasma temperature of 300 eV).For example, the file name of Al.ca represents the opacity data of Al plasma at a density of 0.005 g/cm3 and a temperature of 2 eV, and the file name of Au.gj represents the opacity data of Au plasma at a density of 0.1 g/cm3 and a temperature of 300 eV. In each file (for examples Al.ca or Au.gj), the first line gives information of atomic number, chemical potential of the plasma, and electron number density in units of cubic meter (m3), the second lines gives information of plasma temperature, density and average degree of ionization, the third line gives the Rosseland and Planck mean opacities, and the fourth lines indicates that the first column refers to photon energy in eV and the second column refers to the opacity at this photon energy.
