A high-precision measurement of excitation energies in ²²Mg was performed using the ²⁵Mg(³He,⁶He)²²Mg reaction as a different approach to study this proton-rich, astrophysically interesting nucleus. The reaction was studied at 51.0 MeV with the Enge split-pole spectrograph at Yale. Proton-unbound states at 6.051(4) and 6.329(6) MeV were observed, confirming a recent identification of these new states with the ²⁴Mg(p,t)²²Mg reaction. There is no evidence in our data of a previously reported state at 5.837 MeV.
