Modified semiempirical Stark shifts of ArII lines

Measurement of Stark broadening and shift of singly ionized Ar lines

“…For shifts, comparisons with experimental works again offer good accordance with the work from Dzierzega and Musiol [18] and lower results (in absolute value) than those obtained in an extensive work by Morris and Morris [10]. Now by comparing with theoretical data, very good agreement is found with calculations from Kršljanin and Dimitrijević [22], with greater differences with the values predicted by Griem [21].…”

“…Most of the papers published in the last 30 years concerning the Stark broadening and shift parameters of Ar II lines are experimental works [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], many of them compiled and evaluated by Konjević and Wiese [19,20]. We have found only two theoretical calculations [21,22]. A very quick look at all these data reveals the existence of a wide spread among the experimental values and systematic differences between them and the theoretical values.…”

The electron-impact broadening effect in hot star atmospheres: The case of singly- and doubly-ionized zirconium

“…For example, for Xe II 6s−6p transitions, the averaged ratio between experimental and theoretical widths is 1.15±0.5 (Popović & Dimitrijević 1996c). In Kršljanin & Dimitrijević (1989) Stark shifts for 47 Ar II multiplets have been calculated within the framework of the MSE method and compared to selected (Konjević & Wiese 1976;Konjević et al 1984) experimental data. Mean experimental-to-theoretical shift ratio of 1.26 ± 0.34 has been obtained.…”
