摘　　要：High-resolution collinear fast-ion-beam-laser spectroscopy has been applied to investigate the optical isotope shifts for transition 4f^(4)5d^(6)K_(11/2)-(24445)°_(11/2) of NdⅡ.From the measured optical isotope shifts,changes in mean-square nuclear charge radiiδ(r^(2))(fm^(2))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.
