Measured, calculated and predicted Stark widths of the singly ionized C, N, O, F, Ne, Si, P, S, Cl and Ar spectral lines

Abstract

In order to find reliable Stark width data, needed in plasma spectroscopy comparision between the existing measured, calculated and predicted Stark width values was performed for ten singly ionized emitters: C, N, O, F, Ne Si, P, S, Cl and Ar in the lower lying 3s - 3p, 3p - 3d and 4s - 4p transitions. These emitters are present in many cosmic light sources. On the basis of the agreement between mentioned values 17 spectral lines from six singly ionized spectra have been recommended, for the first time, for plasma spectroscopy as spectral lines with reliable Stark width data. Critical analysis of the existing Stark width data is also given.

Stark broadening parameters in singly and doubly ionized fluorine spectra

“…A number of calculations of the Stark parameters, related to the F II, F III spectral lines, on the basis of different theoretical approaches is presented in the literature (Griem 1974;Hey 1976;Hey & Breger 1981;Dimitrijević & Konjević 1981;Dimitrijević 1988a,b). Furthermore, in Djeniže (2000), on the basis of regularities within an isonuclear sequence, Stark widths of F II 402.50 nm spectral lines (3s−3p transition) are predicted. In Djeniže et al (1999) regularities of Stark widths of several F II spectral lines within the same transition (3s −3p ) are presented.…”
