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