Abstract
Beam-laser and beam-roil measurements of the lifetimes of the 5p 2P(o) levels in Cd II are used to obtain the f-value or the 5s 2S-5p 2P(o) multiplet. The beam-laser results give an f-value of 0.745 +/- 0.012 w hile the beam-foil results incorporating cascade correction give 0.708 +/- 0.045, the large uncertainty coming mainly from a 6% uncertainty in the post-foil ion velocity. The results are discussed in light of t he experimental and theoretical data available for the lower-Z ions of the Ag I isoelectronic sequence.
