The level structure of neutron-deficient 58Zn has been extracted experimentally. This nucleus is important for the rapid proton-capture process. 58Zn was produced by using a (d,n)-type transfer reaction on 57Cu in inverse kinematics at beam energies of 75 MeV/u. Several γ-ray transitions have been identified. The experiment utilized the state-of-the-art GRETINA γ-ray energy tracking array in conjunction with the largeacceptance spectrometer S800 at NSCL. The excitation energies of the identified low-lying states in 58Zn are important for constraining the 57Cu(p,γ)58Zn reaction rate under X-ray burst conditions.
