Abstract With doppler-reducedintermodulatedoptogalvanicsaturation laserspectroscopy (IMOGS) in Eu I the isotope shift (IS) and hyperfine structure (hfs) of the remainingb 8 D term of the configuration 4f 7 5d 6s was investigated. With the help of former measurements in our group (a 6,10 D) and by other authors (a 8,10 D) the IS of the now complete configuration (20 levels) was analysed with wavefunctions by J.-F. Wyart. From the parametric description of the IS resulted the necessity also to include the often neglected small parameterg 1(g 1(4f, 5d)=9.3(3) MHz), which is mainly due to the specific mass shift. The IS of all 20 levels can be well described by further crossed-second-order parametersg 2(5d, 6s)=−401(5) MHz andg 3(4f, 6s)=−27(1) MHz and one commonJ-dependent parameterz 5d =40.4(4.1) MHz. — With effective one-electron parametersa kl ,b kl an interpretation of the magnetic and electric hfs (except for a few disturbed levels) could also be carried out.
