This work reports Stark shifts and widths of 15 Art lines measured in a pul
sed are. Plasma parameters, electron density and temperature, range in this
experiment from 0.25 to 0.98 x 10(23) m(-3) and from 13 500 to 26500 K, re
spectively. The former has been measured interferometrically at a single wa
velength and spectroscopically from the H-alpha-Stark broadening. The latte
r has been measured from the Boltzmann plot of Ar rr lines and from the rat
io of Ar Ir and Art line intensities. Comparisons with most of the data pub
lished to date about this topic in Arl are also included.
