Radiative lifetimes of nine levels in Eu II (4f(7)6p, 4f(6)5d6s and 4f(6)5d
(2)) and Eu III (4f(6)5d) have been measured using time-resolved laser-indu
ced fluorescence spectroscopy on a laser-produced europium plasma. Oscillat
or strengths for a number of Eu II lines have been derived by combining the
lifetimes with branching ratios measured in the emission spectrum of a hol
low-cathode lamp.
