“…In the fourth multiplet ( 3 P 1 ) 5d[3]-( 3 P 2 ) 4f [4] • , there is a considerable difference between the widths of the two lines, as well as between their shifts, even though both lines have a blueshift. Fifth multiplet ( 3 P 2 ) 6p [3] • -( 3 P 2 ) 6d [3] also shows irregular behaviour for both widths and shifts, but not as emphasized as in previous cases.…”

“…In papers [1,2], Wiese and Konjević established three types of regularities or systematic behaviour of Stark parameters: (i) regularities within a spectrum, which are either systematic trends along spectral series for atoms and ions of simple structure or similarities within multiplets, supermultiplets and transition arrays for emitters with more complex spectra, (ii) similarities for analogous transitions of homologous atoms and ions and (iii) systematic trends for a fixed transition of ions within an isoelectronic sequence. There were also attempts to find other kinds of regularities, such as [3] and references therein.…”

This work reports measurements of nine Stark widths and nine Stark shifts of Xe II spectral lines. These line parameters have been measured in a pulsed arc plasma in electron density and temperature range (0.2–1.6) × 1023 m−3 and (18 000–25 000) K, respectively. The results are compared to other experimental data as well as with theoretical values calculated from modified semiempirical formulae. Stark parameters of the lines belonging to the same multiplet are usually very close. The results obtained in this work show that in some cases very clear intramultiplet irregularities exist. These measurements, as well as some results from the previous works of this group, have been used to analyse the origin of these irregularities.

“…This method to quickly estimate Stark broadening parameters, is mainly elaborated in Serbia (see e.g. [26][27][28][29][30][31][32][33]). The aim of such studies is to find out how regularities and systematic trends can be used to predict line widths and to critically evaluate experimental data.…”

The significance of Stark broadening for Solar and stellar plasma research is discussed. Since the influence of Stark broadening within a spectral series increases with the increase of the principal quantum number of the upper level, the Stark broadening contribution may become significant for Rydberg atoms and ions where the optical electron is weakly bound to the core. Consequently, e.g. high member Balmer series lines may be used for Solar plasma diagnostic. The importance of Stark broadening for sub photospheric layers modelling is discussed also. The methods and results developed and obtained on Belgrade Astronomical Observatory and in Serbia are principally discussed .

“…If one takes into account the simplicity of this method, the agreement is good for the width and within the error bars for the shift. On the basis of examination of systematic trends (Purić et al 1985(Purić et al , 1987(Purić et al , 1991(Purić et al , 1993Purić 1996), dependencies enabling the estimation of the Stark widths of spectral lines due to s-p and p-s transitions of neutral atoms have been found by Sarandaev et al (2000). These simple relations, based on the known ionization potential of the lower/upper level of the corresponding transitions and on the regularities and systematic trends, have been used to determine Stark widths for Ge I 4p 2 1 S-5s 1 P 0 and 4p 2 1 S-5s 3 P 0 transitions.…”
