Electron impact broadening of spectral lines in Be-like ions: quantum calculations

We present in this paper quantum mechanical calculations for the electron impact Stark linewidths of the 2s3s–2s3p transitions for the four beryllium-like ions from N IV to Ne VII. Calculations are

The impact of improved Stark-broadening widths on the modeling of double-ionized chromium lines in hot stars

Stellar atmosphere modeling and chemical abundance determinations require the knowledge of spectral line shapes. Spectral lines of chromium in various ionization stages are common in stellar spectra

Electron Broadening Operator Including Penetrating Collisions for Hydrogen

The expression of the electron broadening operator including the effect of penetrating collisions, i.e., for which the incoming electron enters the extent of bound-electron wave-functions, is rather

Matrix Methods for Solving Hartree-Fock Equations in Atomic Structure Calculations and Line Broadening

Atomic structure of N-electron atoms is often determined by solving the Hartree-Fock equations, which are a set of integro-differential equations. The integral part of the Hartree-Fock equations

Stark broadening models for plasma diagnostics

A review of the models used for the calculation of the Stark broadening spectrum for plasmas is presented. The aim is to provide an overview of the related theories using a simple formalism, useful




The Stark widths of the Ne VII 2s3s-2s3p singlet and triplet lines are calculated in the impact approximation using quantum-mechanical convergent close-coupling and Coulomb-Born-exchange

Quantum mechanical calculations of the electron impact broadening of isolated ion lines

Quantum mechanical calculations have been carried out for the broadening by electron impact of the lines Mg+3p-3s at 2802 AA and Ca+4p-3d at 8542 AA. The line broadening function is averaged over the

Stark Broadening of the B III 2s-2p Lines

We present a quantum-mechanical calculation of Stark linewidths from electron-ion collisions for the 2s{sub 1/2}-2p{sub 1/2,3/2}, {lambda}=2066 and 2067 {Angstrom}, resonance transitions in BIII. The

Quantum-mechanical calculation for the electron-impact broadening of the resonance lines of singly ionized magnesium

Using close-coupling calculations of Burke and Moores for the scattering of electrons by ${\mathrm{Mg}}^{+}$ ions in the $3^{2}S_{\frac{1}{2}}$ and $3^{2}P_{\frac{1}{2},\frac{3}{2}}$ states,

Stark profile calculations for Lyman series lines of one-electron ions in dense plasmas. Interim report

The frequency distributions of the first six Lyman lines of hydrogen-like carbon, oxygen, neon, magnesium, aluminum, and silicon ions broadened by the local fields of both ions and electrons are

Experimental Stark Widths and Shifts for Spectral Lines of Neutral and Ionized Atoms (A Critical Review of Selected Data for the Period 1989 through 2000)

We have extended our critical review of the available experimental data on Stark widths and shifts for spectral lines of non‐hydrogenic neutral atoms and positive ions by one year, including the year

R-matrix with pseudo-states calculation for electron collisions with neutral beryllium

We have extended and further improved our previous R-matrix with pseudo-states (RMPS) calculation for electron collisions with beryllium (1996 J. Phys. B: At. Mol. Opt. Phys. L769 - 72). Results for

The convergent-close-coupling method is extended for the calculation of electron-hydrogen scattering to hydrogenlike targets, atoms, or ions, and is found to give better agreement with experiment than any other over this entire energy range.


The work of two previous papers is extended and a theory of pressure broadening is developed which treats the perturbers quantum mechanically and allows fur inelastic collisions, degeneracy, and

Experimental Stark Widths and Shifts for Non-Hydrogenic Spectral Lines of Ionized Atoms (A Critical Review and Tabulation of Selected Data),

Abstract : A critical review of all available data on the Stark widths and shifts for lines of non-hydrogenic ionized spectra has been carried out. The relevant literature compiled by the NBS Data
