Noble gas line profiles in dense plasmas. I. Argon

Measured Stark widths and shifts of the neutral argon spectral lines in 4s–4p and 4s–4p′ transitions

“…In Refs. [18,22,30], electron temperatures are similar with ours so taking into account the approximate normalization factor W t /N e and d t /N e , we have found that our Stark width is 30% higher in average than theirs, and that the Stark shift is 15% higher in average than theirs. It is important to point out that all papers [10 -30] for these seven Ar I spectral lines refer to the sum of the electron (W e ) and ion (W i ) contributions to the total Stark width (W t ) and to the sum of the electron (d e ) and ion (d i ) contributions to the total Stark shift (d t ) without estimating the contribution of electrons and ions separately.…”

Modified semiempirical Stark shifts of ArII lines

“…Comparison of MSE and semiclassical [12] ArlI Stark line shifts with reliable experimental data [4][5][6][7][8][9][10][11], at N~= 1017 cm -3. Columns are: (1) transition arrays, (2) multiplets, (3) line wavelengths, (4) electron temperatures of the experiments, (5) experimental shifts at Ne= 1017 cm -a, (6) accuracy (data in columns 1-6 were taken from [2,3,11]; accuracy of the experiment [11] is estimated according to criteria of [2,3]), (7) reference numbers of the experiments, (8) experimental to theoretical line shifts ratios for semiclassical results [12], and (9) the same ratios for present MSE results. Cases where experimental and theoretical shifts have the opposite signs are denoted by asterisks [2,3] for all experiments considered, except [4] with somewhat higher accuracy, and because of the fact that all measurements are performed in temperature Table 3.…”

“…MSE approach for ion lines Stark broadening [23][24][25]11 was tested several times [27][28][29][30][31][32][33][34][35][36]3, 1] and on the average gives a satisfactory agreement with experiments. It also served as source of Stark broadening data for astrophysical needs E30, [37][38][39] [4][5][6][7][8][9][10][11] were taken from the critical reviews of experimental data by Konjevi6 and Wiese [2] and Konjevi6 et al [3].…”
