Abstract
The Stark shift of the CI 2479 Å emission line of atomic carbon is measured in a broad range of electron densities between ~6 × 1016 and ~4 × 1018 cm–3. It is established that the shift is linear and its value is significantly lower than that predicted by theory. The line shape is found to be dominated by the Stark effect at Т = 32 kK and electron concentration Ne ≈ 3.9 × 1018 cm–3. The electron-impact and ion widths of this contour are in good agreement with the Grim data, while its total shift to longer wavelengths is found to be half that calculated theoretically.
