Spectroscopy and lifetime measurements in Te-134,Te-136,Te-138 isotopes and implications for the nuclear structure beyond N=82 Benito García, Jaime Fraile Prieto, Luis Mario Sánchez, V. Vedia Fernández, María Victoria otros, ... 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 U-238 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 6(1)(+) state in Te-136 and the (6(1)(+)), (4(1)(+)), and (2(1)(+)) states in Te-138 and discuss the results in the context of large-scale shell-model calculations. The level schemes of Te-136 and Te-138 are revised in terms of lifetimes of their 2(1)(+), 4(1)(+) states and updated information on the (4(2)(+)) state in Te-136 is presented. In addition, previously reported data on spectroscopy and lifetimes in Te-134 are reexamined. This work provides new insights into the evolution of collectivity for Te isotopes with N = 82, 84, 86. 2023-06-17T09:13:41Z 2023-06-17T09:13:41Z 2023-06-17T09:13:41Z 2021-03-22 journal article https://hdl.handle.net/20.500.14352/8433 2469-9985 10.1103/PhysRevC.103.034317 eng ENSAR2 (654002) (FPA2015-65035-P; FPA2015-65035-P; RTI2018-098868-B-I00) ST/L005743/1 ST/P005314 05P15RDFN1 05P19PKFNA BL 1513/1-1 263030 https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Amer Physical Soc
