Abstract

We have refined and extended an existing technique for determining an atomic transition probability by carefully measuring the transition branching ratio (BR) and excited-state lifetime (τ), with particular attention paid to systematic errors. The technique was applied to the red region of the 238U i spectrum where little accurate data is presently available. In particular, we find for the 6395.42 Å transition the following values: τ = 607 ± 20 ns, BR = 0.586 ± 0.05, and g 2A = 1.45 × 107 ± 1.25 × 106.
