Bound excited states in the neutron-deficient nucleus Mg-21 were probed in the one-neutron knockout reaction Be-9(Mg-22, Mg-21+gamma)X at 74 MeV/nucleon projectile energy. The low-lying level scheme of Mg-21 was investigated for the first time with gamma-ray spectroscopy. Contrary to the interpretation of previous particle spectroscopy data, our proposed excitation scheme is in agreement with the mirror nucleus and shell-model calculations in the p-sd shell. Spectroscopic factors for the one-neutron removal from Mg-22 to Mg-21 are extracted and compared to shell-model calculations using the WBP effective interaction.
