Abstract
The 84;85 Br nuclei have been produced as flssion fragments in the fusion reaction 18 O + 208 Pb at 85MeV bombarding energy and studied with the Euroball IV array. The high-spin states of the odd- odd 84 Br nucleus have been identifled for the flrst time, the observed structure being built on the known 6 i isomeric state. High-spin states of 85 Br have been observed up to 5.4MeV excitation energy and spin I » 21=2. From angular correlation analysis, spin values have been assigned to most of the 85 Br excited states up to 4MeV. None of these excited states has been found to exhibit a delayed decay having T1=2 > 10ns. All the observed states in 84;85 Br can be described by various proton excitations involving at least the two sub-shells (…f5=2 and …p3=2) located just above the Z = 28 shell closure.
