Gyromagnetic ratios of low-lying rotational states in^{156, 158, 160}Gd

Transient-field precessions were measured simultaneously for levels in the ground-state bands of^{156, 158, 160}Gd as ions of these nuclei traversed a thin polarized Fe foil. Relative g-factors of levels up to 6₁⁺ were deduced, those of the 4₁⁺ levels being determined with greatest precision. In contrast with the conclusions of the recent report by Alzner et al. [1], our results are consistent with g(4₁⁺) having the same value in all three isotopes and imply g(2₁⁺)=g(4₁⁺) in¹⁵⁶Gd, consistent with nuclear structure models.
