Semiclassical perturbation Stark widths of singly charged argon spectral lines

Abstract Using a semiclassical perturbation approach with the impact approximation, Stark widths for singly charged argon (Ar ii) spectral lines have been calculated. Energy levels and oscillator strengths needed for this calculation have been determined using the Hartree–Fock method with relativist...

Zusammenfassung:Abstract Using a semiclassical perturbation approach with the impact approximation, Stark widths for singly charged argon (Ar ii) spectral lines have been calculated. Energy levels and oscillator strengths needed for this calculation have been determined using the Hartree–Fock method with relativistic corrections. Our Stark widths are compared with experimental results for 178 spectral lines. Our results may be of interest not only for laboratory plasma, lasers and technological plasmas but also for white dwarfs and A- and B-type stars.
