Nuclear Physics and Applications

Two sets of strongly coupled rotational bands have been identified in 62Zn. These bands have been observed up to the terminating states of their respective configurations. Lifetime measurements indicate that the transition quadrupole moments in these bands decrease as termination is approached. These results establish the first terminating states of rotational bands in the A∼60 mass region and confirm the predicted loss of collectivity associated with smooth band termination.Received 8 September 1997DOI:https://doi.org/10.1103/PhysRevLett.80.2558©1998 American Physical Society
