Hydrogen Stark Broadened Brackett lines [PDF]

open access: yesInternational Journal of Spectroscopy, 2010
Stark-broadened lines of the hydrogen Brackett series are computed for the conditions of stellar atmospheres and circumstellar envelopes. The computation is performed within the Model Microfield Method, which includes the ion dynamic effects and makes the bridge between the impact limit at low density and the static limit at high density and in the ...

Stark broadening parameter tables for Kr VIII [PDF]

open access: yesSerbian Astronomical Journal, 1999
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 6 Kr VIII multiplets as a function of temperature and perturber density.

Stark Broadening of Al IV Spectral Lines

open access: yesUniverse, 2023
Stark widths for 23 transitions in Al IV have been calculated by employing the modified semiempirical method. The results are obtained for an electron density of 1017 cm−3 and temperatures from 10,000 K to 160,000 K.

Stark broadening parameter tables for Na X [PDF]

open access: yesSerbian Astronomical Journal, 1998
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 57 Na X multiplets as a function of temperature (200 000 K - 5 000 000 K) and perturber density (1017cm−3 - 1024cm−3.

Effect of the Ions on the Electron Collision Operator through Electronic Trajectory Modification

open access: yesAtoms, 2019
We investigate the ion effect on the broadening of the spectral line profile by the free electrons collisions with the emitters in plasmas. We only considered the weak collisions’ contribution.

Stark Broadening of Sn Ii Spectral Lines

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Stark broadening parameters, full widths at half intensity maximum, and shifts for 34 multiplets of singly charged zinc ion have been calculated using the impact semiclassical perturbation formalism. Stark broadening parameters due to collisions with electrons, protons, and helium ions have been obtained for a grid of electron ...
