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 539.1 Neutron-Rich Física nuclear 2207 Física Atómica y Nuclear 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.
