Lifetimes and Oscillator Strengths for the 6<i>p</i>7<i>s</i>³P_0,1Levels in Bi II

Abstract

Lifetime measurements and empirical branching ratio estimates for the 6p7s3P0 and 3P1 levels in Bi II are reported, together with supporting theoretical calculations. These results are combined to yield absorption oscillator strengths between these levels and those of the 6p2 ground configuration. The results are discussed in the context of spectroscopic data obtained from orbiting telescopes.
