Core-polarization Effects for the Stark Broadening of Pb III Spectral Lines: Predictions and Regularities
Using a semi-classical approach, we have calculated values of the Stark broadening parameters for several lines of Pb III. Stark widths and shifts are presented for an electron density of 1017 cm– 3 and temperatures T = 11000-100000 K. In this work, we have carried out a study of the influence of the introduction of the terms that allow us to take into account the Core Polarization (CP) effects...
متن کاملQUADRATIC STARK CONSTANTS OF NEUTRAL COPPER SPECTRAL LINES IN THE COULOMB APPROXIMATION
Quadratic Stark constants of neutral copper spectral lines for all s,p, and d levels are calculated using the Coulomb approximation. These results are compared with existing data and, generally, good agreement is observed
متن کاملStark width and shift measurements of visible Si III lines
A set of experimental Stark width and shift parameters of visible doubly ionized silicon spectral lines is reported in this paper. Measurements have been made on a pulsed plasma generated in a linear discharge lamp filled with a mixture of silane and helium. Electron density and temperature in this plasma range from 0.2 to 0.9 × 10 23 m −3 and from 17 500 to 21 000 K respectively. Electron dens...
متن کاملStark Broadening of A III and AIV Lines*
The half-widths of five A III and two A I V lines have been measured in a pulsed arc operated in an argon-nitrogen mixture. Electron densities of 3.8 to 8.0 x 1016 c m 3 were determined by laser interferometry at a single wavelength while electron temperatures from 20750° to 23100 ° K were measured from the relative intensities of A l l lines. The experimental A III and A I V Stark profile half...
