γ-ray Spectroscopy of Se-85 produced in Th-232 fission Benito García, Jaime Fraile Prieto, Luis Mario Sánchez Tembleque Verbo, Víctor Vedia Fernández, María Victoria Artículo firmado por 73 autores. This work was supported in part by the National Science Centre, Poland (NCN) under contract No. UMO-2015/18/E/ST2/00217, by the German Research Foundation (DFG) under grant No. BL 1513/1-1, by the NuSTAR DA BMBF 05P15RDFN1, and by the Spanish MINECO via projects FPA2015-65035-Pand RTI2018-098868-B-I00. Excited states in the neutron-rich Se-85 nucleus have been studied using for the first time a fast neutron-induced fission of Th-232. The experiment was performed at the ALTO facility of the IPN Orsay. Coupling of the LICORNE directional neutron source with the nu-ball high-resolution gamma-ray spectrometer provided unique access to high-spin states in neutron-rich fission fragments from the Th-232(n,f) reaction. A preliminary level scheme of Se-85 was established by the analysis of prompt gamma-gamma-gamma coincidences. Identification of the all known yrast states in Se-85 is the first step towards studies of more neutron-rich Se isotopes. 2023-06-16T15:25:43Z 2023-06-16T15:25:43Z 2020 journal article 0587-4254 10.5506/APhysPolB.51.843 https://hdl.handle.net/20.500.14352/6649 https://doi.org/10.5506/APhysPolB.51.843 https://www.actaphys.uj.edu.pl/ eng (FPA2015-65035-P; RTI2018-098868-B-I00) UMO-2015/18/E/ST2/0021 BL 1513/1-1 05P15RDFN1 https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Jagellonian University
