Wavelengths and atomic parameters for both dielectronic and inner-shell satellite lines of the type Is n£ -1s2J.' ni, with n = 2, 3, and 4, have been calculated for Ti XX. The atomic data were calculated in a mulr iconfiguration intermediate coupling scheme and are compared with previc -; results for n = 2. The intensities of the higher n satellites are derived from these data, and thus an estimate of the contribution of the unresolved dielectronic satellities to the resonance line is obtained.

... Direct excitation rates are also given for the resonance, intercombination and forbidden lines for He-like titanium. Cascades and the effect of resonances for these lines are not considered in this paper. These results are used to fit an experimental soft X-ray spectrum from the PDX (Poloidal Divertor Experiment) tokamak discharge. Good agreement is obtained between computed and observed spectra.
