On the stark broadening of ionized nitrogen lines

In this paper, we report an analysis of the experimental procedure and results obtained in a recently published paper on the Stark broadening of singly-, doubly-, and triply-ionized nitrogen lines. The results of this analysis indicate that the influence of self-absorption on the line profiles is not taken into account properly and that therefore the results of Ref. 6 cannot be applied with confidence. Comparisons of experimental results with numerous theoretical calculations have also been performed.
