Abstract
Transient field precessions of the first excited states in have been measured. The states were excited by the inverse Ca, 2pCr reaction and the recoil nuclei traversed a thick gadolinium foil, where they experienced the rotation. The observed precessions, for the ,,, states of the ground-state band, were equal within experimental error indicating these states have g factors similar to that of the state value of 0.55±0.10 measured previously. This feature is contrary to the predictions of the shell model and suggests a higher collectivity for the ground-state band. Limited results were also obtained for the cross conjugate nucleus supporting this conclusion.
