Hydrogen Stark Broadening Calculations With
The unified theory has been generalized for the case of upper and lower state interaction by introducing a more compact tetradic notation. The general result is then applied to the Stark broadening of h>drogen. The thermal average of the time development operator for upper and lower state interaction is presented. Except for the time ordering it contains the effect of finite interaction time be...
متن کاملSemiclassical Calculations of Stark Broadening Parameters
A review of semiclassical calculations of Stark broadening parameters is presented. We compare the results obtained by using computer codes due to (i) Jones, Benett and Griem, ( i i ) Sahal-Brechot and ( i i i ) Bassalo, Cattani et Walder. The comparison with experimental results has also been discussed.
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 کاملNon-thermal Effects in Stark Broadening*
When an atom is immersed in a plasma the energy levels are broadened and shifted by the interaction with the fluctuating electric field of the plasma. We discuss the effect of this field on the spectral line shape by the use of results from plasma kinetic theory. In particular we show that in the equilibrium plasma the dominant effect is from single-particle collisions although correlation effe...
