摘要Accurate atomic data such as fine-structure energy levels and oscillator strengths are calculated to obtain the radiative opacity and transmission of iron plasmas. At a temperature of 22 eV and a density of 0.01 g/cm(3), the calculated transmission spectrum is in better agreement with the experiment than that by other opacity codes such as OPAL. The transmission spectrum is very sensitive to the temperature of plasmas, meaning that it is an ideal diagnostic tool for the temperature of plasmas. Practical calculations show that the uncertainty of the temperature diagnostics obtained by theoretical predictions is better than +/-2eV.
