Stark shift of neutral and ionized silicon spectral lines

Quantum mechanical line widths of ionized oxygen, silicon, and aluminium; comparisons with recent experimental results

“…In conclusion, our quantum Stark widths are the most close to the experimental results (nearly 25 per cent for all the lines). The experimental results of Konjević et al (1970) and Purić et al (1973) present the higher disagreement with our quantum calculations and the semi classical ones. We remark also that -in almost all the cases-these experi-mental Stark widths are underestimated compared to our quantum ones, but agree with the simplified modified semi empirical results G(SMSE).…”

“…We calculate the Stark broadening of 9 spectral lines. Our quantum Stark HWHM and the available theoretical ones: semi classical (Griem 1974), results of Gavanski et al (2016) obtained by using the modified semi empirical theory of Dimitrijević & Konjević (1980) and its simplified form of Dimitrijević & Konjević (1987) are compared to the experimental results of: Konjević et al (1970); Purić et al (1973); Lesage & Miller (1975); Lesage et al (1977Lesage et al ( , 1983; Lesage & Redon (2004); Chiang & Griem (1978); Pérez et al (1990Pérez et al ( , 1993; Wollschläger et al (1997); González et al (2002); Bukvić et al (2009), and the recent experiments of Gavanski et al (2016).…”

Measurement of Stark Halfwidths of Spectral Lines of Ionized Oxygen and Silicon Emitted from T-tube Plasma

“…Second, Stark halfwidths obtained in [35] were compared to values published by other authors [1, [4][5][6][7][8][9][10][12][13][14][15]17,18,20,23,25,26]. Third, all experimental halfwidth values, both from [2] and from [1, [4][5][6][7][8][9][10][12][13][14][15]17,18,20,23,25,26], were compared to theoretical values [57,58] by calculating the ratio of experimental to theoretical halfwidths. The analysis in this paper is performed only for those experimental results of other authors which contain data for more than one line in the observed multiplets.…”

“…Stark halfwidths of SI II spectral lines, which were measured in [35], satisfy the proposed multiplet criterion very well, with deviations from the average halfwidth value being less than 3.5%. The results published in [9,10,13,17] also meet this criterion, while some results in [8,12,14,15,18] do not. An overview is given in Table 2.…”

“…In this work, a comprehensive analysis of the experimental Stark halfwidth data of ionized oxygen and silicon is presented. The analysis is performed on experimental results measured in [2] and the available results of other authors [1, [4][5][6][7][8][9][10][12][13][14][15]17,18,20,23,25,26]. A comparison with theoretical results [57][58][59] is also given.…”
