Abstract
The transition rates of the intercombination lines 2s2p3 5So2→2s22p2 3P1,2 are computed using a systematic configuration interaction method (SCIV3). The calculated lifetime of the upper 5So2 level is in excellent agreement with a recent experiment. The branching ratio of the two lines is very different from earlier, less accurate theoretical values.Keywords
