Abstract
The profiles of some copper spectral lines have been observed in a freeburning low-current arc between copper electrodes. The half-widths between 0.3 and 0.6 cm- 1 have been measured by a Fabry- Perot glass interferometer. The observed Voigt- profiles have been separated into Lorentzian and Gaussian components whereby it was possible to determine gas temperature and electron concentration. The gas temperature obtained is lower than the electron temperature determined from the relative line intensities.
