摘要：

The isotope shifts and hyperfine splittings of atomic optical lines in 132,134-Nd-143 (lambda = 588.79 nm), 138-145Sm (lambda = 600.42 nm) and 138-145Eu (lambda = 576.52 nm) have been measured using resonance ionization spectroscopy. The magnetic dipole and electric quadrupole moments of the odd Nd and Sm isotopes and the changes in mean square charge radii delta < r2 > for all isotopes in question have been derived. A shell effect and a strong Z-dependence in the isotopic behaviour of delta < r2 > at N < 82 have been observed. The experimental data have been analysed in the framework of the Hartree-Fock method.
