Abstract
The photoionization process of the C5+ ion in warm, dense plasmas is studied using the relativistic approximation. Cross section calculations are performed for plasma density and temperature ranges of ne ∼ 1023–1026 cm−3 and Te = 150–300 eV, respectively. The used static screened potential includes the effects of plasma degeneracy, finite-temperature gradient corrections to the kinetic energy, and quantum exchange-correlation. The dependencies of the photoionization cross section on plasma density (for fixed temperature) and temperature (for fixed density) are investigated.
