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 Neutral Boron Lines

open access: yesAtoms, 2019
Stark broadening parameters, width and shift, of lines within B I 2s22p−2s2ns spectral series have been calculated. Semi-classical theory in impact approximation has been applied. Temperature dependence of Stark parameters has been studied.

Line Shape Modeling for the Diagnostic of the Electron Density in a Corona Discharge

open access: yesAtoms, 2017
We present an analysis of spectra observed in a corona discharge designed for the study of dielectrics in electrical engineering. The medium is a gas of helium and the discharge was performed at the vicinity of a tip electrode under high voltage.

Stark broadening parameter tables for In II [PDF]

open access: yesSerbian Astronomical Journal, 2000
Electron-, proton-, and ionized helium-impact broadening parameter tables for In II spectral lines, are presented as a function of the temperature and the perturber density. Calculations have been performed within the semiclassical perturbation approach.

Stark broadening of Xe VIII spectral lines [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Stark broadening parameters have been calculated for 60 spectral lines of Xe VIII, for broadening by electron, proton, and He III impacts. For calculations, the semiclassical perturbation approach in the impact approximation has been used. The widths and shifts are provided for temperatures from 20 000 K to 500 000 K and for an electron density of 10 ...

Stark Widths of Ar II Spectral Lines in the Atmospheres of Subdwarf B Stars

open access: yesAtoms, 2017
Stark broadening parameters are of interest for many problems in astrophysics and laboratory plasmas investigation. Ar II spectral lines are observed in many kinds of stellar atmospheres such as the atmospheres of B-Type stars and subdwarf B stars.

Stark broadening of N II spectral lines [PDF]

open access: yesSerbian Astronomical Journal
The Stark broadening parameters, widths, and shifts, for spectral lines within the 45 N II multiplets, were calculated for collisions with electrons, protons and helium ions, by using the semiclassical perturbation method. The obtained data were

Stark broadening parameter tables for Kr II lines [PDF]

open access: yesSerbian Astronomical Journal, 2000
In order to provide the Stark broadening data for ion lines from complex spectra, here we present calculated Stark widths and shifts for 37 Kr II lines. The calculations were performed by using the modified semiempirical approach.

On the Stark broadening of Ru III spectral lines [PDF]

open access: yesBulletin of Natural Sciences Research, 2021
Stark broadening parameters, full widths at half maximum (FWHM) and shifts for spectral lines within six multiplets of doubly charged ruthenium ions have been calculated, for an electron density of 10 17 cm-3 and temperature range from 10 000 K to 160 ...
