An experiment to search for new excited states in the proton-rich nucleus57Cu was performed at the Heavy Ion Laboratory of the University of Warsaw. This nucleus, with one valence proton outside the doubly magic56Ni core, offers a sensitive test of Shell Model predictions in interplay with collective effects, and its structure is essential for the production of heavier elements in the astrophysical rp-process. A fusion–evaporation reaction was employed using an 85 MeV beam of32S ions incident on a28Si target. The emitted γ-rays, neutrons, and light charged particles were detected with the EAGLE, NEDA, and DIAMANT arrays, respectively. No γ-ray lines corresponding to57Cu could be identified. An upper limit for the57Cu production cross section was estimated as σ = 3 µb.
