Abstract
We report on spectroscopic information and lifetime measurements of even-even neutron-rich Te isotopes. Excited states were populated in fast-neutron induced fission of at the ALTO facility of IJCLab with the LICORNE neutron source and detected using the hybrid -ball spectrometer. We provide first results on lifetimes of the state in and the (), (), and () states in and discuss the results in the context of large-scale shell-model calculations. The level schemes of and are revised in terms of lifetimes of their states and updated information on the state in is presented. In addition, previously reported data on spectroscopy and lifetimes in are reexamined. This work provides new insights into the evolution of collectivity for Te isotopes with .
