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 Neutral Helium 5016 Å Line
Plasma spectral line broadening is an important tool for plasma diagnostic in both laboratory and astrophysical field. The neutral helium lines are used e.g., in industrial applications and to determine the properties of stellar atmospheres of hot stars. In local thermal equilibrium, the spectral line profile is related to the dipole autocorrelation function which is related to the two-particle...
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...
