AB  - We present the results of an experimental study of the DC Stark shift for seven visible NeI lines in the plane cathode sheath region of an abnormal glow discharge operated in neon with a small admixture of hydrogen. The electric field (up to 13.4 kV cm(-1)) in the cathode sheath region is measured from the p-polarized profile of the H alpha line of hydrogen using the Stark polarization spectroscopy technique. Within the realized range of the electric field, the NeI lines exhibit a quadratic Stark effect. The values of coefficients, correlating Stark shift and electric field strength, were determined, enabling their future use for unknown electric field strength measurements. Among the studied lines, so far only the Stark effect analysis of the NeI 511.367 nm line has been reported, in which case our results are in good agreement with the best fit formula proposed by Jager and Windholz (1984 Phys. Scr. 29 344) for one out of three Stark components detected under our experimental conditions.

AB  - We report the results of five Ne I line shapes study in an abnormal Grimm-type glow discharge operating in
neon. The spectral lines were observed along the axis of a cylindrical glow discharge parallel (side-on) and
perpendicular (end-on) to the cathode surface. The side-on spectra showed a spectral line shift and
sometimes a simultaneous shift and split in the cathode fall region of the glow discharge. The results of
the measured line shift with the available data for the dc Stark effect were used to estimate the electric
field strength in the cathode fall region of the glow discharge. The end-on recorded line profiles showed
up to 30% larger half-widths than the side-on recorded line profiles from the negative glow. This effect
is a result of the superposition of line emission in the cathode fall region under the influence of the dc
Stark effect on the line profile from the negative glow. In addition, wavy features at the far wing in the
direction of dc Stark shift were detected. All observed phenomena related to end-on line shapes in
Grimm discharge were related quantitatively to the dc Stark effect in the cathode fall region and plasma
line broadening in the negative glow region.

AB  - We report the results of an Ar I and Ne I line shape study in an abnormal glow discharge operating in argon and neon. The spectral lines were observed along the axis of a cylindrical glow discharge parallel (side-on) and perpendicular (end-on) to the cathode surface. The side-on spectra show spectral line shifting and sometimes simultaneous shifting and splitting in the cathode fall region of the glow discharge. The results of the measured line shift with available data for the dc Stark effect are used for measurement of electric field strength in the cathode fall region of the glow discharge. Electron temperatures of 2860 K and 4770 K in the negative glow region of argon and neon discharges, respectively, were determined from the relative intensities of Ar I or Ne I lines using the Boltzmann plot technique. An electron number density of approximate to 10(20) m(-3) (+/- 25%) in the negative glow region of the argon discharge was determined from the widths of two plasma-broadened Ar I lines using theoretical Stark broadening data. The end-on recorded line profiles show 10-40% larger half-widths than the side-on recorded line profiles from the negative glow. This effect is a result of the superposition of line emission in the cathode fall region under the influence of the dc Stark effect on the line profile from the negative glow.
