Abstract: The laser-induced resonance fluorescence in an atomic beam was used in order to measure the hyperfine splitting of the 4f 7 6s 2 and 4f7 6s6p levels in 151,153,155Eu isotopes. The hfs constants A and B of the unstable 155Eu were determined for the first time: MHz, MHz and MHz. With these data and after corrections for second-order hyperfine structure perturbations the nuclear moments of 155Eu were deduced: n.m. and b. In addition new and more precise values of the hfs constants of the excited state for the stable 151,153Eu were obtained. They are as follows: MHz, MHz and MHz, MHz. The hyperfine anomalies % and % were extracted from the corrected hfs constants.
