Resumen

The ¹¹⁶Sn nucleus contains a collective rotational band originating from proton π 2p-2h excitations across the proton Z= 50 shell gap. Even though this nucleus has been extensively investigated in the past, there was still missing information on the low-energy interband transitions connecting the intruder and normal structures. The low-lying structure of¹¹⁶Sn was investigated through a high-statistics study of the β^-decay of^116m1In with the 8 π spectrometer and its ancillary detectors at TRIUMF. These measurements are critical in order to properly characterize the π 2p-2h rotational band. Weak γ-decay branches are observed utilizing γ-γ coincidence spectroscopy methods, leading to the first direct observation of the 85 keV 22+→03+γ ray with a transition strength of B(E2) = 99. 7 (84) W.u. The analysis of these results strongly suggests that the 2027 keV 03+ state should replace the previously assigned 1757 keV 02+ state as the band-head of the π 2p-2h rotational band.
