Calculation of the photoabsorption coefficient in a hot and dense aluminum plasma

The photoabsorption coefficient of high-temperature (${10}^2$-${10}^5$ eV) and high-density (${10}^{20}$-${10}^{22}$ ${\mathrm{cm}}^{-3\mathrm{}}$) aluminum plasma in the range of $h\nu ={10}^2-{10}^5$ eV is calculated. The calculation uses detailed configuration accounting. The photoabsorption mechanisms included are the photoelectric effect, inverse bremsstrahlung, Compton effect, and bound-bound photoexcitation. The Stark broadening of the sharp-line and the absorption-edge structure is properly taken into account and its influence versus ion density is shown. The sensitivity of the results to changes in the various parameters is discussed.
