E(level): From least-squares fit to Eγ data. All levels listed here above the first 2+ level at 1356 keV are proton unbound.
Jπ(level): From systematics of even-even nuclei, shell-model predictions, and mirror analogy with 58Ni nucleus
Additional Level Data and Comments:

58Zn nucleus is of astrophysical interest since it is deemed as a waiting-point nucleus in rp process in X-ray bursts
1998Jo18 (also 2000Oi04): 58Zn produced and identified in Nb(p,X) E=1 GeV at ISOLDE at CERN using selective laser-ion source. Measured Eγ, Iγ, βγ coin, isotopic half-life
2002Lo13 (also 2002Bl17): 58Zn obtained from fragmentation of 78Kr beam at 73 MeV/nucleon at GANIL using LISE spectrometer. Measured isotopic half-life
2005Ka46: 58Zn produced and identified in Nb(p,X) E=1.4 GeV at ISOLDE at CERN using selective laser-ion source. Measured Eγ, Iγ, βγ coin, isotopic half-life. No delayed protons were observed from 58Zn isotope. The authors state that analysis of 58Ni(3He,3n) (same reaction as was used by 1983HoZY) experiment is in progress to detect protons
2007Bl09: fragmentation of 70Ge beam at 71.6 MeV/nucleon with Ni target. Measured production cross section.
2009Fu15: fragmentation of 64Zn+29 beam at 79 MeV/nucleon with natural Ni target at LISE3, GANIL facility. Measured half-life by measuring β-delayed γ-ray activity.
2012OrZY: 58Zn produced in Ni(58Ni,X),E=74.5 MeV/nucleon using LISE3 facility at GANIL. Detected 58Zn fragments through tof, E-ΔE measurements followed by detection of β particles. Half-life of ground state was measured from β-decay curve. This is an independent experiment by the same group as 2009Fu15. Through an e-mail communication of July 30, 2014 with Professor B. Rubio at University of Valencia, another experiment had been done for a precise measurement of ground-state half-life, results of which were communicated to the evaluator
Others:
1983HoZY: possible identification in 58Ni(3He,3n) reaction, claimed to have observed delayed protons. This work remains unpublished.
1994Fo07 (also 1996Fo08,1987Zu03): 58Ni(π+,π-) E=120-292 MeV; measured excitation function for double charge exchange reaction on t=1 target: 58Ni(π+,π-)58Zn, leading to double isobaric analog states and compared data with theoretical calculations
1986Se04: 58Ni(π+,π-) E=292 MeV, deduced mass excess
2001Fo07: reaction rates of 57Cu(p,γ)58Zn and levels of 58Zn from shell-model calculations. The first 2+ state is predicted at 1400
2006Va21, 2004Va38: Structure calculation for Pseudo-orbital SO(6) symmetry in 58Zn, 58Cu and 58Ni
Q-value: Estimated uncertainty=210 in S(n) (2012Wa38).
Q-value: Q(εp)=6500 50, S(2n)=32860 510 (syst), S(2p)=2970 50 (2012Wa38)
