摘要：

In 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 x 10(23) to 1.15 x 10(23) m(-3) and electron temperature from 16 000 to 26 000 K.
