Radiative lifetimes of 12 odd-parity and 73 even-parity levels of Eu I, 26 even-parity levels of Eu II, and three even-parity levels of Eu III have been measured with time-resolved laser-induced fluorescence. These lifetimes are accurate to ±5%. In

New radiative lifetime measurements using time-resolved laser-induced fluorescence are reported for the lowest six even-parity levels of Eu II. Branching fractions, measured from Fourier transform spectra, are combined with these lifetimes to determi

Absolute atomic transition probabilities are reported for many of the strongest lines in Tb II (the second spectra of terbium). Branching fractions were measured from Fourier transform spectrometer (FTS) data and combined with radiative lifetimes fro

We report spectroscopic measurements on the 6s6p 3P1 level of Lu+ at 28503.16 cm-1. The radiative lifetime of this level was measured to be 37.4 ± 1.9 ns using time-resolved laser-induced fluorescence of a slow ion beam. Branching fractions were det

We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe levels with energies between 25 900 and 60 758 cm . Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the ra
