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-induced fluorescence spectroscopy on a laser-produced europium plasma. Oscillator 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 hollow-cathode lamp
