![عکس صفحه اول مقاله: Orbital relaxation effects on temperature diagnostics of mid-Z plasmas Orbital relaxation effects on temperature diagnostics of mid-Z plasmas](/preview/png/5429942.png)
The orbital relaxation effect was studied in the calculations and diagnostics of the L-shell absorption spectra (2pâ3d,4d,5d) of iron and bromine plasmas. A detailed level accounting model was developed to calculate the huge number of L-shell absorption lines of the two typical mid-Z plasmas. The orbital sets were generated by the optimizations according to the initial and final states, respectively. It was found that the L-shell line positions agree with the experimental iron and bromine spectra better when the orbital relaxations were included in calculations. Since experimental mid-Z spectra have few detailed line structures, calculations without considering orbital relaxations may misinterpret the spectra and consequently lead to underestimations of the plasma temperatures.
