讨论了目前有关2 2 Na(p ,γ) 2 3Mg反应的实验研究工作 ,结合兰州放射性束流线上的放射性束流2 3Al的β+延发质子衰变实验的测量结果 ,给出了2 3Al延发衰变的质子能谱 ,并比较了近期实验给出的相关能级的自旋、宇称值 ,正是由于这种自旋、宇称和能级部分宽度的不确定性 ,导致了反应率计算的不确定性 .计算了同位旋相似态的共振强度 .对于测量到的新的延发衰变能级Ed =8.91 6MeV ,由于没有相应的能级宽度值 ,实验仅给出其相对共振强度值 In the present paper, the experimental research on the reaction of 2 2 Na (p, γ) 2 3Mg is discussed. Based on the measurement results of 2 + 1 proton decay experiment of 2 + 3 beams of radioactive beam in Lanzhou radioactive beam, The proton energy spectrum of the decay is extended and the spin and parity values ​​of the related energy levels given by the recent experiments are compared. It is because of the uncertainty of the width of the spin, parity and energy level that the reaction For the uncertainty of the rate calculation, the resonance intensity of the isospin-like phase is calculated. For the new extended decay energy level Ed = 8.91 6MeV, since there is no corresponding energy level width, the experiment only gives the relative resonance strength value
