摘要：

Low-lying excited levels in 116Te were studied by measuring level lifetimes with the recoil-distance Dopplershift method in the 112Sn(12C, 8Be) 116Te alpha-transfer reaction and angular correlations following the beta decay of 116I. Both experiments were performed at the Cologne FN Tandem accelerator. Several new levels were discovered below 3.2 MeV excitation energy, spins and multipole mixing ratios were determined via angular correlations. Lifetimes were measured for the 2+1 , 0+2 , 22+, and 4+1 and upper limits for lifetimes were determined for higher lying levels. The experimental findings are compared to calculations in the U(5) limit of the interacting boson model and are also discussed in the framework of shape coexistence which is expected in midshell Te isotopes.
