Zakopane 2026 Conference on Nuclear Physics

The structure of neutron-deficient nuclei in the vicinity of 70Br provides a sensitive testing ground for investigating shape evolution, proton–neutron correlations, and isospin-symmetry breaking through Coulomb energy differences. To address these questions, an experiment was performed at the Heavy Ion Laboratory of the University of Warsaw. Excited states in nuclei around A≈70 were populated in fusion–evaporation reactions induced by an 88 MeV 32S beam on a 40Ca target. The experiment took advantage of the complex detector system, recently upgraded by fully digital data acquisition, comprising: the γ-ray spectrometer EAGLE coupled to the neutron and charged-particle detector arrays: NEDA and DIAMANT.
This contribution presents the current status of the data analysis. The performance of the experimental setup is investigated in terms of its sensitivity to weak gamma transitions emitted by evaporation residues produced in particle evaporation reaction channels. The possibility of expanding the spectroscopic information regarding the studied nuclei is discussed.
