Hl. Ma et al., CHANGES IN MEAN-SQUARE NUCLEAR-CHARGE RADII OF ND-II FROM OPTICAL ISOTOPE SHIFTS BY COLLINEAR FAST-ION-BEAM LASER SPECTROSCOPY, Chinese Physics Letters, 15(3), 1998, pp. 178-179
High-resolution collinear fast-ion-beam-laser spectroscopy has been ap
plied to investigate the optical isotope shifts for transition 4f(4) 5
d K-6(11/2) - (24445)(11/2)degrees of Nd N. From the measured optical
isotope shifts, changes in mean-square nuclear charge radii delta[tau(
2)] (fm(2)) among live even-even neodymium isotopes have been deduced:
(142, 144) 0.282, (144, 146) 0.242, (146, 143) 0.274, (148, 150) 0.40
4. The results are in good agreement with experimental data from elect
ronic x-ray spectroscopy and combined optical and x-ray spectroscopy.
