متن کاملNonthermal Broadening of Uv Lines Observed at the Limb Ofthe Quiet
We have done a spectroscopic study of the solar transition region using high resolution UV & EUV data obtained by SUMER(Solar Ultraviolet Measurements of Emitted Radiation) on board SOHO(Solar and Heliospheric Observatory). Optically thin and conspicuous emission lines observed at the solar limb are carefully selected to acquire average values of physical parameters for the quiet region as a fu...
متن کاملBroadening of resonance lines by charged dislocations
It is shown that the random electric fields of charged dislocations in insulators should cause appreciable broadening of sharp resonance lines such as spin-resonance signals. The degree of broadening is very sensitive to the screening of the dislocations by charged point defects. Since the shape of the inhomogeneously broadened resonance line monitors the distribution of the internal fields, th...
متن کاملPressure broadening of an anticrossing signal
2014 We show that the pressure broadening of the width 2 ~(4 V2 + (01270393)2) of an anticrossing signal (where V is the coupling between the anticrossing levels and 0393 the reciprocal of their lifetime) is caused by more than just the increase of 0393 by collisions. We find that the linewidth is given by 2 ~(4 V2 ab03B3/03B3 + (0127 ab03B3)2), where ab03B3/03B3 is the ratio of the effective r...
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...
