Gyromagnetic ratios of low-lying rotational states in156, 158, 160Gd

Abstract

Transient-field precessions were measured simultaneously for levels in the ground-state bands of156, 158, 160Gd 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. Show more
