    Notizen: Abstract The quadratic Stark effect in the hyperfine structure of all levels of the configuration 4f 7(8 S)6s6p in europium I, which can be excited by electric dipole radiation from the ground state, has been investigated by laser-atomic-beam spectroscopy. From the measured shifts and splittings of the hyperfine components the scalar and tensor polarizabilities have been deduced. From the polarizabilities radial integrals for electric dipole radiation were determined by a parametric analysis. With these radial integrals theoretical values of the polarizabilities were calculated.

    Notizen: 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.
