Excited states in the neutron-rich nucleus ⁶⁸Fe were populated using a ⁹Be(⁶⁸Co, ⁶⁸Fe + γ)X charge-exchange reaction at 95 MeV/u. The new γ-ray transitions reported here for the first time complement data from β-decay studies and nucleon knockout reactions. In comparison to shell-model calculations with the LNPS effective interaction, two candidate states for the $$6$$$^{+}_{1}$$ level emerge. Here, the distinct population pattern of excited states and the magnitude of the cross section, σ_inc = 0.51(6) mb, make this reaction a promising one for future in-beam γ -ray spectroscopy. Reaction calculations with nuclear structure input from a new, locally optimized Hamiltonian, f7j4a, together with general considerations for heavy-ion-induced charge-exchange reactions appear consistent with most of the observations, although challenges remain.
