Levels in {sup 22}Mg between 4 and 7 MeV excitation energy have been populated in a high-resolution study of the {sup 24}Mg(p,t){sup 22}Mg reaction. Two new states have been observed at energies E{sub x}=5090 and 6323 keV, while two states were observed at 5962 and 6046 keV. The precision in measured excitation energies for several other {sup 22}Mg levels has been improved substantially. In addition, a new state at 8141 keV was observed in {sup 23}Mg. Using spin and parity restrictions from the present and previous work, we discuss T=1 analog state assignments of A=22 nuclei below 7 MeV excitation energy. The implications for the rate of the stellar reaction {sup 21}Na(p,{gamma}){sup 22}Mg which takes part in hydrogen burning during nova outbursts are presented.
