Abstract

Fission fragments from neutron-induced fission of 235U produced at the high-flux reactor of the Institut Laue-Langevin, Grenoble, were separated with the Lohengrin separator to provide a beam of neutron-rich 85As nuclei. The β - decay of 85As to 85Se was studied using γ-γ and β-γ coincidence techniques. 85Se was also studied using the prompt-γ coincidence data from spontaneous fission of 248Cm and 252Cf measured with the Eurogam2 and Gammasphere Ge arrays, respectively. The combination of β decay and prompt-γ data enabled the determination of spins and parities of low-energy excited states in 85Se. There are new arguments supporting the 5/2 - assignment for the ground state of 85As. © 2012 American Physical Society.
