Effect of the Ions on the Electron Collision Operator through Electronic Trajectory Modification
Atoms, 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 the B III 2s-2p Lines [PDF]
, 1997 We present a quantum-mechanical calculation of Stark line widths from electron-ion collisions for the $2s_{1/2}-2p_{1/2,3/2}$, lambda = 2066 and 2067 A, resonance transitions in B III.

Line Shape Modeling for the Diagnostic of the Electron Density in a Corona Discharge
Atoms, 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]
Serbian 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.

From the Vector to Scalar Perturbations Addition in the Stark Broadening Theory of Spectral Lines
Universe, 2021 The effect of plasma Coulomb microfied dynamics on spectral line shapes is under consideration. The analytical solution of the problem is unachievable with famous Chandrasekhar–Von-Neumann results up to the present time.

Stark broadening of Cd I spectral lines [PDF]
Astronomy & Astrophysics, 2005 Stark broadening parameters, widths, and shifts for 33 Cdl singlets and 37 triplets were calculated using the semi-classical perturbation method. The results were compared with available experimental and theoretical data. Also, regularity in the spectral series 5s 2 S-np 1 P° was investigated.

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

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

Stark broadening parameter tables for Kr II lines [PDF]
Serbian 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.
