Transient field precessions of the first excited states in [sup 50]Cr have been measured. The states were excited by the inverse [sup 12]C([sup 40]Ca, 2[ital p])[sup 50]Cr reaction and the recoil nuclei traversed a thick gadolinium foil, where they experienced the rotation. The observed precessions, for the 2[sup +],4[sup +],6[sup +],8[sup +] states of the ground-state band, were equal within experimental error indicating these states have [ital g] factors similar to that of the 2[sup +] state value of 0.55[plus minus]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 [sup 46]Ti supporting this conclusion.
