Smooth Termination of Collective Rotational Bands

Abstract: Rotatoinal cascades observed in neutron-deficient nuclei with Z ~51 are described as the first examples of smoothly terminating bands in heavy nuclei, since they show a continuous transition from high collectivity to a noncollective state. Excellent agreement between experiment and calculations in the Nilsson-Strutinsky cranking model is obtained for the 109Sb nucleus.
