Stark broadening of resonance transitions in B III
Physical Review A, 1996We performed line profile measurements of the 2s-2p resonance transitions in B III in order to test quantum-mechanical (close-coupling) theory. The experiment was carried out using the well-diagnosed gas-liner pinch discharge where plasma parameters are determined independently by 90\ifmmode^\circ\else\textdegree\fi{} Thomson scattering.

Stark broadening of He i lines
AIP Conference Proceedings, 1994Close-coupling methods for electron impact broadening have been extended to the Stark broadening of neutral helium lines. The comparison with semiclassical impact theories reveals significant differences, particularly at low electron temperatures. Ion broadening is included by the use of the model microfield method.

Electron correlations in stark broadening
Journal of Quantitative Spectroscopy and Radiative Transfer, 1969Abstract It is shown that the previous calculations of electron correlation effects in Stark broadening are in error because of an incorrect evaluation of the electric field autocorrelation function. The corrected result involves the screening of both fields in the autocorrelation function.

Dynamic Stark broadening as the Dicke narrowing effect
Physical Review E, 2010A very fast method to account for charged particle dynamics effects in calculations of spectral line shape emitted by plasmas is presented. This method is based on a formulation of the frequency fluctuation model (FFM), which provides an expression of the dynamic line shape as a functional of the static distribution of frequencies.

On the Stark broadening of Lyman-β
Journal of Quantitative Spectroscopy and Radiative Transfer, 1972Abstract Classical-path calculations for the Stark broadening of the Lyman-β line of hydrogen are presented using a procedure outlined in a previous paper. All multipoles in the perturber (free electron)—atom interaction are included and time ordering of the operators in the S-matrices is retained. Comparison is made with previous calculations.

Accuracy of Stark Broadening Calculations for Ionic Emitters
Physical Review Letters, 1998The standard static-ion impact electron theory of line broadening is assessed with a calculation of the He II P-alpha line over a broad range of plasma conditions. Ion dynamics, an improved electron collision operator, and accurate atomic physics are included in the computation.

Stark Broadening of Neutral Helium Lines in a Plasma
Physical Review, 1962The frequency distributions of spectral lines of nonhydrogenic atoms broadened by local fields of both electrons and ions in a plasma are calculated in the classical path approximation. The electron collisions are treated by an impact theory which takes into account deviations from adiabaticity.

On the Stark broadening of Co II spectral lines
Astronomical and astrophysical transactions, 2016Stark full widths at half maximum for 12 Co II multiplets have been calculated using modified semiempirical method. The obtained results have been also used to demonstrate the importance of Stark broadening mechanism in DB white dwarfs.
