Shifts due to collisions with charged particles (Stark broadening ) and neutral atoms, were determined for nine argon spectral lines corresponding to the transitions 3p5nd-3p54p for n = 4-7, 3p56s-3p54d and 3p54p’ -3p54s in order to estimate their usability for the research and diagnostics of a plasma in a surface-wave discharge at atmospheric pressure. Lifetime Broadening . by LASH65. The typical internal uncertainty on the line positions is estimated to be ~10 m/s (3.3 parts in 10^8 or 0.18 mA), which is a factor of 2-10 better than the widely used Los Alamos Atlas of the Thorium Spectrum (Palmer & Engleman 1983). As can be seen in the different compilations of lines [10] and spectral terms [12, 13], the spectra of highly ionized argon is relatively less well known than those of the other atoms of the isoelectronic sequences. by Dark_fox.

The ion broadening parameters of several argon and carbon spectral lines are determined by fitting asymmetric theoretical profiles to spectral line profiles obtained in a wall-stabilized arc experiment. Add to SeaMonkey Add to collection More Nature Themes. Modern argon lasers remove blue wavelength light, allowing photocoagulation to be achieved at 514 nm which reduces light scatter as well as preventing absorption of the blue 488-nm wavelength by xanthophyll in the macula. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.… Read More; Stokes lines.
