Abstract: Excited states in the T<subscript>z</subscript>= 0 nucleus <superscript>70</superscript>Br have been investigated using the reaction <superscript>58</superscript>Ni(<superscript>16</superscript>O,1 p3 n). γ rays were detected with one EUROBALL CLUSTER detector and three single HPGe detectors. Charged particles and neutrons were registered with the Rossendorf silicon ball and six modules of the EUROBALL neutron wall, respectively. The identification of γ transitions in <superscript>70</superscript>Br is based on the analysis of γγ-proton-neutron coincidences. A level scheme of <superscript>70</superscript>Br has been established for the first time. It shows a multiplet-like structure of probably isospin T= 0 while T= 1 isobaric analogue states are not observed. [ABSTRACT FROM AUTHOR]
