Abstract High-resolution collinear fast-ion-beam-laser spectroscopy has been applied to investigate the optical isotope shifts for transition 4f45d6K11/2-(24445)°11/2 of Nd II. From the measured optical isotope shifts, changes in mean-square nuclear charge radii δ(r2) (fm2) among five even-even neodymium isotopes have been deduced: (142,144) 0.282, (144, 146) 0.242, (146, 148) 0.274, (148, 150) 0.404. The results are in good agreement with experimental data from electronic x-ray spectroscopy and combined optical and x-ray spectroscopy.
