Abstract

Three rotational bands in 74 Kr were studied up to (in one case one transition short of ) the maximum spin Imax of their respective single-particle configuratio ns. 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 Imax . This feature, together with the results of mean field calculations, indicates that the observed bands do not terminate at I=Imax .
