Abstract

High-spin states in the nucleus Te-116 have been studied with the reaction Ni-64(Fe-56,2p2n) at 236 MeV using an early implementation of the Gammasphere array. Three rotational bands extending to spins I similar to(25-42)(h) over bar and excitation energies E(ex)similar to(11-24) MeV have been identified and connected to known low-lying states. In the most extended band, a gradual decrease in the dynamic moment of inertia J((2)) with increasing rotational frequency has been observed and interpreted as evidence for smooth band termination. Several energetically favored states based on aligned single-particle configurations also have been found to coexist with weakly deformed collective structures at low spins.
