Stark widths of many prominent 6s-6p and 5d-6p transitions have been measured and compared with theoretical results. A high current pinched discharge was used as a spectroscopic source. Electron density and temperature were estimated in 2.65 x 1022m--3 and 1.45 x 104K respectively.Experimental Stark widths agree well with previous theoretical results.Our data are compared with those of other authors concerning to the homologous ions Ne 11, Ar 11, Kr I1 and Xe 11.

A simple and fast method for the measurements of transition probabilities for lines obtained from pulsed sources is presented. Measuring the linewidth and peak intensities transformed in an internal absolute scale, relative transition probabilities are obtained from a simple relation. The method is useful only for lines with Lorentzian or Voigt type profiles, but many transitions are of this form. For testing the method, 6s-6p Xe II transitions were selected since several works exist for comparison.
