SPECTRAL-LINE PROFILES OF N=4 TO N=5 TRANSITIONS IN C-IV, N-V AND O-VI

We report on measurements of Stark profiles of the n = 4 to n = 5 tran sitions in the lithium-like ions C IV, N V and O VI. The measurements were performed in a plasma of the gasliner pinch discharge where elect ron densities and temperatures are determined independently by 90-degr ees Thomson scattering. The comparison of the experimental data with t heoretical calculations shows good agreement for all spectra especiall y when ion dynamics effects are taken into account.
