Abstract

The photoabsorption coefficient of high-temperature (10/sup 2/--10/sup 5/ eV) and high-density (10/sup 20/--10/sup 22/ cm/sup -3/) aluminum plasma in the range of h..nu.. = 10/sup 2/--10/sup 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.
