Stark broadening measurements of Al II, Al III and He I 388.86 nm spectral lines at high electron densities

, 2020
Experimental Stark width broadening parameters (w) for 5 spectral lines of singly (Al II) and 8 spectral lines of doubly ionized aluminum atoms (Al III) are presented. The for Al III values are the first experimental data. The experiment was conducted in

Stark broadening in krypton and xenon

Physical Review A, 1989
Mesure de l'elargissement des raies visibles Kr I, Kr II et Xe II derriere des ondes de choc reflechies dans un tube de choc a diaphragmes. Des evaluations revisees de l'elargissement par des mecanismes en competition reduisent les parametres de Stark pour 7 raies de Xe II.

Determination of the Stark broadening coefficients of tantalum emission lines by time-independent Extended C-sigma method

, 2020
In this paper we introduce a new time-independent Extended C-sigma approach for the analysis of Laser Induced Breakdown Spectroscopy (LIBS) spectra and apply it to the determination of the Stark broadening coefficient of several neutral and ionic ...

Stark broadening of germanium

Physical Review A, 1974
Stark broadening parameters of the more prominent visible germanium lines are measured in a 1-eV shock-tube plasma. Estimated accuracies for eight observed Ge II and two Ge I lines are (10-30)%. Ionic results are compared with semiclassical predictions.

Band Gap Renormalization, Carrier Multiplication, and Stark Broadening in Photoexcited Black Phosphorus.

Nano letters (Print), 2018
We investigate black phosphorus by time- and angle-resolved photoelectron spectroscopy. The electrons excited by 1.57 eV photons relax down to a conduction band minimum within 1 ps.

Stark Broadening of Hydrogen Lines in a Plasma

Physical Review, 1959
The frequency distributions of hydrogen lines broadened by the local fields of both ions and electrons in a plasma are calculated in the classical path approximation. The electron collisions are treated by an impact theory which takes into account the Stark splitting caused by the quasi-static ion fields.

Calculation of electron density and temperature of plasmas by using new Stark broadening formula of helium lines

Physics of Plasmas, 2019
In this work, three helium lines are considered to find the density and the temperature of the electrons (Ne and Te) in a plasma jet. We have, at first, developed a new formula for Stark broadening through an exact contribution of the weak collisions of ...

Investigation of the Stark Broadening of Balmer Beta

Journal of Physics B: Atomic and Molecular Physics, 1981
The Stark broadening of the Balmer line Hbeta was studied in a high-current wall-stabilised arc at electron densities between 1.75 and 14.4*1016 cm-3. The electron density was obtained by means of a two-wavelength Michelson interferometer. The reduced half-widths of Hbeta were compared with the theories of Griem et al. (1962), Vidal et al. (1973) and

On the Stark Broadening of Lu III Spectral Lines

Journal of Astrophysics and Astronomy, 2015
The electron-impact widths for 27 Lu III spectral lines have been calculated by using the modified semiempirical method. Calculations have been also performed with the published relativistic Hartree-Fock oscillator strengths and additionally, with the approximate formula of Cowley.

Stark broadening of neutral xenon

Physical Review A, 1981
Stark broadening of prominent visible Xe I lines are measured in three independent experiments. The three studies all use quiescent shock-tube plasmas as emission sources, but each employs distinctly different instrumentation, shock-heating regimes, and analytical methods. Owing to conditions in the light sources, temperatures between 9200 and 12 500 K,
