Electron correlations in stark broadening

Journal of Quantitative Spectroscopy and Radiative Transfer, 1969
Abstract 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.

Stark broadening of He i lines

AIP Conference Proceedings, 1994
Close-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.

Stark broadening of resonance transitions in B III

Physical Review A, 1996
We 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 neutral potassium lines

Journal of Quantitative Spectroscopy and Radiative Transfer, 1987
Abstract Using a semiclassical approach, we have calculated electron-proton and Ar II impact line widths and shifts of 50 neutral potassium lines. The comprehensive set of results obtained is used for investigation of Stark-broadening-parameter regularities within the spectral series.

Stark shift/broadening by stimulated emission

Optical Society of America Annual Meeting, 1991
Previous experimental work by our group1 has shown that the two-photon excitation of the 6p[1/2,0] state of xenon has a fairly sharp threshold for the onset of amplified spontaneous emission (ASE) from the 6p[1/2,0] state to the excited 6s state. The excitation probability has the expected quadratic dependence on excitation intensity below the ASE ...

Stark broadening of neutral sodium lines

Journal of Quantitative Spectroscopy and Radiative Transfer, 1985
Abstract A semiclassical approach has been used to evaluate Stark broadening of atomic lines and also electron-and proton-impact line widths and shifts of 30 neutral sodium lines. The results are used to investigate Stark broadening-parameter regularities within the spectral series.

Stark broadening of AgI spectral lines

Atomic Data and Nuclear Data Tables, 2003
Abstract Using a semiclassical approach, we have calculated electron-, proton-, and ionized helium-impact line widths and shifts for 48 Ag I lines, for perturber densities 10 13 –10 19  cm −3 and temperatures T =2500–50,000 K.

Stark broadening of singly ionized-silicon

Physical Review A, 1977
Linewidths and shifts of the five prominent visible Si II multiplets are measured in a conventional shock tube. The Stark effect from impacting plasma electrons is the dominant broadening mechanism. Electron densities range widely ((4--15) x 10/sup 16/ cm/sup -3/), but temperatures (9500--12 500 /sup 0/K) do not.

STARK BROADENING CALCULATIONS OF SEVERAL LINES

2013
This work reports calculated Stark broadening transition of several Ti lines at 1064 nm in a laser-produced plasma (ne = 2.27-1.59 × 1019 cm−3). The method is based on the assumption of homogenous plasma and local thermodynamical equilibrium (LTE). Electron temperatures are in the range of 0.79-0.85 eV.
