AbstractAbstract
[en] The existence of rotational structures in nuclei bordering on the spherical Z= 50 closed shell has been known for some time. Nevertheless, our understanding of collective effects in this region is remarkably incomplete; for example, before this work little high-spin data existed and there were no lifetime measurements to confirm the collectivity associated with the rotational bands observed in Sb (Z = 51) and Sn (Z = 50) nuclei. Furthermore, the role of the h11/2 orbital was virtually unknown, although it has the highest angular momentum of the orbitals in this mass region and therefore is expected to have the most influence on the properties of high-spin states. In the A ∼ 130 and A ∼ 180 mass regions, where highly deformed intruder bands have been observed, it is the neutron i13/2 orbitals, respectively, which are preferentially lowered in energy by a combination of large deformation and fast rotation In lighter nuclei the h11/2 orbital is expected to appear as an intruder configuration.
