IntroductionIn a series of experimental [1}3] and theoretical [4}12] papers the Stark parameters of spectrallines of neutral magnesium where parameters are of great interest for diagnostics of laboratory andespecially astrophysical plasmas. Moreover, recently solar infrared spectra of MgI [13, 14] wereobtained and to interpret these spectra one should take into account the contribution of Starkbroadening because its in#uence increases as principal quantum numbers of levels increase.However, experimental data for some levels obtained in di!erent papers di!er dramatically fromone another and from theoretical calculations.One of the ways to estimate the reliability of experimental data and theoretical calculations isdetermination of regularities in the behaviour of the Stark parameters of spectral lines. A series ofsimple regularities to be used with the goal above and to estimate parameters of unstudied lines areproposed in the literature [15}23].In this paper, the regularities allowing us to calculate the widths and shifts of a number of themagnesium lines and to critically analyze the literature data are obtained. These dependenciesenable one to estimate the Stark parameters of non-studied magnesium lines, in particular, we have******Corresponding author.
