Abstract Radiative lifetimes of the 4f 7 (8 S) 6s 6p z 10 P 7/2, 9/2,z 8 P 5/2, 7/2, 9/2 andz 6 P 7/2, 5/2 levels of Eu I were measured by the time resolved recording of the exponential decay of the fluorescence. Three of them were measured for the first time, the others agree with previous determinations. From the values of the lifetimes absolute oscillator strengths are deduced, taking into account the branching ratios for the transitions to the 4f 7 6s 2 and 4f 7 5d 6s levels. From these absolutef values the radial integralI(6s 2, 6s 6p) was derived by a parametric analysis. Theoretical values of oscillator strengths which were calculated using this radial integral show good agreement with the experimental data.
