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

Stark broadening parameters in CII, CIIIand CIVspectra

“…Our new experimental W data obtained between an electron temperature of 17 800 and 20 500 K lie, predominantly, between the G and MSE values. Similar behaviour is found for other experimental data measured earlier in [8][9][10][11] (see figure 5(a)). Our new Stark shift values agree with other experimental data [8,10] and with the SSS [10,26] theoretical predictions.…”

“…In the case of the most researched C II spectral lines that belong to multiplet no 2 (the 3s-3p transition), three theoretical approximations deal with the Stark FWHM values, i.e. the semiclassical approximation (G) [1], the modified semiempirical (MSE) approximation [11,19] and the non-stationary theory of broadening (SSS) [10,26]. Besides, estimated W values based on the obtained Stark width regularities along a carbon isonuclear sequence (INS) [8,41] also exist.…”

“…The spectra of the ions treated in this paper are of great interest in the spectroscopy of fusion (tokamak) plasmas as well. Few papers have been dedicated to C II Stark width [5][6][7][8][9][10][11] and shift [6,8,10] measurements. In the case of C III only two experiments have dealt with Stark width [8,12] and one [8] with Stark shift determination of the 229.689 nm C III spectral line.…”

Stark-broadening calculations of singly ionized carbon spectral lines

“…Therefore we may conclude that the experiments of Blagojević et al (1999) and Srećković et al (2000) are in excellent agreement with the theoretical results for the 2s 2 3p 2 P o –2s 2 3d 2 D multiplet. For the 2s 2 3s 2 S–2s 2 3p 2 P o multiplet, our theoretical results are also in excellent agreement with the experimental data of Blagojević et al (1999), as well as with those of Sarandaev & Salakhov (1995). They are in very good agreement, better than 30 per cent (which is well within error bars), with the data of Srećković et al (2000).…”

“…The visible spectrum was covered by Djeniže et al (1988) and Perez et al (1989): both authors used a low‐pressure pulsed arc. Sarandaev & Salakhov (1995) used an impulsive capillary discharge, Blagojević et al (1999) produced plasma with a low‐pressure pulsed arc and more recently Srećković et al (2000) investigated a large spectral range using a linear low‐pressure pulsed arc.…”
