moreIn this paper, we present results of experimental determination of Stark parameters of Ar II
spectral lines. We report 126 half-width and 111 shift results, 53 half-widths and 44 shifts
of which are presented here for the first time. The obtained data may be of astrophysical
interest. The results were compared with available experimental results of other authors and
with calculated ones in the cases where it was possible. A low-pressure pulsed arc, filled with
pure argon, was used as a plasma source. All measurements were done under electron density
which ranges from 0.20 × 1023 to 1.15 × 1023 m−3 and electron temperature from 16 000 to
26 000 K.
