Comparison of explicit calculations forn=3–8 dielectronic satellites of the Fe xxv Kα resonance line with experimental data from the tokamak fusion test reactor

Dielectronic satellite spectra of the Fe xxv K{α} resonance line observed from tokamak fusion test reactor plasmas have been compared with recent explicit calculations for the n=3--8 dielectronic satellites as well as the earlier theoretical predictions, which were based on the 1/n³ scaling law for n>4 satellites. The analysis has been performed by least-squares fits of synthetic spectra to the experimental data. The synthetic spectra constructed from both theories are in good agreement with the observed data. However, the electron-temperature values obtained from the fit of the present explicit calculations are in better agreement with independent measurements.
