SYSTEMATIC CIV3 AND MCDF CALCULATIONS FOR THE UV0.01 MULTIPLET IN O-III

We have carried out accurate, systematic calculations for the 2s2p(3 5 )S(2)(o)-2s(2)2p(2 3)P(1,2) E1] lines at 1660.807 and 1666.153 Angstro m in O III. Uncertainty estimates for their A values and the lifetime of the S-5(2)o level have been determined from a set of quality criter ia. A lifetime of 1.21 +/- 0.06 ms is recommended for this level, in e xcellent agreement with a recent experiment. The contributions to the branching ratios and lifetimes from different effects (e.g. core-valen ce correlation and Breit interaction) are discussed.
