The Mid - Infrared [ S iv ] / [ Ne ii ] versus [ Ne iii ] / [ Ne ii ] Correlation
The mid-infrared ratio [Ne iii]15.6μm/[Ne ii]12.8μm is a strong diagnostic of the ionization state of emission line objects, due to its use of only strong neon emission lines only weakly affected by extinction. However this ratio is not available to ground-based telescopes as only a few spectroscopic windows are available in the MIR. To deal with this problem we aimed to verify if there exists ...
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 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...
متن کاملOn the Stark broadening of the B III 2s− 2p lines
We present a quantum-mechanical calculation of Stark line widths from electron-ion collisions for the 2s1/2−2p1/2,3/2, λ = 2066 and 2067 Å, resonance transitions in B III. The results confirm the previous quantum-mechanical Rmatrix calculations but contradict recent measurements and semi-classical and some semi-empirical calculations. The differences between the calculations can be attributed t...
متن کاملStark Broadening of Hydrogenic Spectral Lines by Langmuir Turbulence in Magnetic Fusion Plasmas: Diagnostic Possibilities
We derive the dynamical Stark width and shift of hydrogenic spectral lines caused by Langmuir turbulence in magnetic fusion plasmas. We show that this additional broadening mechanism can dominate over the Stark broadening by the plasma microfield, theories of the latter broadening being also discussed. We also derive conditions necessary for Langmuir-wave-caused dips/depressions to occur in the...
