Three rotational bands in $^{74}$Kr were studied up to (in one case one transition short of) the maximum spin $I_{max}$ of their respective single-particle configurations. Their lifetimes have been determined using the Doppler-shift attenuation method. The deduced transition quadrupole moments reveal a modest decrease, but far from a complete loss of collectivity at the maximum spin $I_{max}$. This feature, together with the results of mean field calculations, indicates that the observed bands do not terminate at $I$=$I_{max}$. |
