N2 - High-resolution laser spectroscopy has been performed for the rare-earth elements as well as Ba by using a tunable diode laser together with a well collimated atomic beam. Hyperfine structures and isotope shifts have been measured for eight transitions in Ba I, Ce I, Sm I, Eu I, Gd I and Yb I. Hyperfine constants A and B have been determined for the 4f75d6s6p 11F5 level of 155,157Gd, and the 4f 146s6p 3P2, 4f146s7s 3S1 levels of 171.173Yb. The field shifts and 6s-electron densities at the nucleus have been derived for the studied elements and compared with the Hartree-Fock calculation.
