In order to test the reliability of the Configuration Interaction (CI) method to predict the atomic parameters viz oscillator strengths of complex ions, we measured the profiles of forth (40) strong 6s-6p transitions of Xe III emitted by a pulsed capillary discharge. After deconvoluting the experimental shapes, Stark widths and relative oscillator strengths were obtained. When Least Square Fitted parameters were used in addition to extensive CI (CI + LSF), the agreement between theory and experiment for the gf's is within a factor two for the whole of the lines. Concerning the widths, the semiempirical approach provides values also within a factor two when the Gaunt factor is taken to be g(x) ~ 0.30.

Stark widths and relative oscillator strengths were measured for more than 130 Xe III spectral lines emitted in a pulsed capillary discharge. As usual, these parameters become attainable once the deconvolution of line profiles is performed. In particular, 4f–6d, 5d–4f, 5d–6p, 6p–6d, 6p–7s and 6s–4f Xe III transitions have been considered. Extensive configuration interaction (CI) along with least-squares fitted atomic parameters were combined in Cowan code calculations, in order to check the quality of agreement with experimental f-values. Comparisons alike, drawn between experimental Stark widths and Griem’s semiempirical approach, guarantee an agreement within a factor of two for the whole of the lines, given a proper choice of the Gaunt factor for each single transition.
