Young. The SSTRUCT calculation used a 17 configuration model of the ion, and term energy corrections were applied. Observed energies were used in the calculation of the A-values. % produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration % % Peter Young - 12-Jun-2006 -1
