Stark broadening of the B III 2 s - 2 p lines

چکیده
We present a quantum-mechanical calculation of Stark linewidths from electron-ion collisions for the 2s1/2-2p1/2,3/2 , l52066 and 2067 Å, resonance transitions in B III. The results confirm previous quantummechanical R-matrix calculations, but contradict recent measurements and semiclassical and some semiempirical calculations. The differences between the calculations can be attributed to the dominance of small L partial waves in the electron-atom scattering, while the large Stark widths inferred from the measurements would be substantially reduced if allowance is made for hydrodynamic turbulence from high-Reynolds-number flows and the associated Doppler broadening. @S1063-651X~97!09612-8#

QUADRATIC 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 broadening of high-members of the helium diffuse series in divertor plasmas
Stark profiles of high-members (n≥7) of the helium triplet diffuse series 1s2p P ◦−1snd D are calculated for tokamak divertor conditions using dipole reduced matrix elements obtained with a hydrogenic approximation. It is shown that the socalled “standard model” of Stark broadening is particularly suited to the description of the isolated lines 1s2p P ◦−1snd D with n = 8−10. Applications to spe...
متن کاملCore-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 کاملStark broadening experiments on a vacuum arc discharge in tin vapor.
Pinched discharge plasmas in tin vapor are candidates for application in future semiconductor lithography tools. This paper presents time-resolved measurements of Stark broadened linewidths in a pulsed tin discharge. Stark broadening parameters have been determined for four lines of the Sn III spectrum in the range from 522 to 538 nm, based on a cross-calibration to a Sn II line with a previous...
