The 116,118Te isotopes lie across the Z=50 shell-closure and present distinct vibrational features in their ground-band states. Recent calculations using density functional theory, as well as the recently developed proxy-SU3 model, have identified these isotopes as good candidates for shape coexistence. In an experiment conducted at the 9 MV Tandem accelerator of IFIN-HH in Magurele, Romania several excited states in 116,118Te were populated via the fusion-evaporation reaction mechanism. A natural Ag target was impinged by a 9Be beam of 35 MeV. The resulting γ-rays were detected by the RoSPHERE detector array equipped with 15 HPGe and 10 LaBr3 (Ce) detectors. The analysis results provide insights to some open questions regarding the nuclear structure of these isotopes. In the present contribution the experimental results on γ-ray spectroscopy of 116,118Te will be presented, with near-future work expected to involve fast-timing measurements to determine the lifetime of excited states.
