Several papers devoted to the Stark widths ofns‐nptransitions of the homologous sequence Neii, Arii, Kriiand Xeiiwere published (n=n0+1, wheren0is the principal quantum number of the ground level). From their analysis, a general trend for this sequence is established in function of two relevant atomic parameters for the description of Stark line widths: the atomic number,Zand the upper level ionization potential. The experiments of Viteletal. shows that, due to a dense plasma effect, a nonlinear dependence between the Stark parameters and the electron density exists:w∝N&ggr;e. From the general trend, the value &ggr;=5/6 is established.
