英文摘要	The reaction of Na-22(p, gamma)Mg-23 has been investigated at the Radioactive Ion Beam Line in Lanzhou(RIBLL) using a radioactive beam Al-23. The beta(+) delayed proton decay spectrum has been measured with the TOF-DeltaE method and zero degree detectors. The half-life of Al-23 is determined to be T-1/2 = (476 +/- 45) ms by using a time scaler combined with the precision pulse generator, which is consistent with the other group's result of (470 +/- 30) ms. The known beta(+) delayed protons at Er = 0.216,0.278,0.438,0.479MeV have also observed in the experiment. The resonance strength of isospin analog state (IAS) is calculated. The resonance intensity of IAS is (11.4 +/- 6.0) meV. A new energy level of beta(+) delayed proton decay has been identified at E-x = 8.916MeV, and their relative intensity also been obtained.
