Abstract
This study presents detailed analysis of theoretical atomic spectra of various argon (Ar) ions, specifically F-like, O-, N-, and C-like Ar ions, calculated using a method implemented in the flexible atomic code, which combines the relativistic configuration interaction method with many-body perturbation theory (FAC-MBPT). Radiative transition rates and oscillator strengths were calculated in terms of length and velocity forms which highlights the accuracy of the calculated data. A collisional-radiative model was developed to calculate theoretical spectra for optically allowed transitions of the four Ar ions. The spectral features and spectral ranges were analyzed and identified. A comparison with available data shows good agreement with the findings. The resulting spectra and the calculated data provide valuable insights for Ar plasma diagnostics and contribute to the understanding of complex astrophysical spectra.
