Experimental stark parameters of 3s2S-3p2P0 multiplet lines of singly ionized carbon

Abstract

Under an impulsive capillary discharge the Stark widths and shifts of singly ionized carbon CII 6578 Å and CII 6583 Å spectral lines have been measured, The electron density has been measured using the hydrogen Hα line width (Ne = 2.21 · 1017 cm-3). The plasma temperature has been determined from the relative intensities of copper CuII 2545 Å and CuII 2490 Å ionic lines (T = 22,000 K). The dependencies for estimating the Stark widths and shifts of singly ionized carbon lines have been proposed. The measured Stark parameters are compared both with the literature data and with the values calculated using the proposed dependencies. © 1995.
