Abstract: The reaction of 22Na(p,γ)23Mg has been investigated at the Radioactive Ion Beam Line in Lanzhou(RIBLL) using a radioactive beam 23Al. The β+ delayed proton decay spectrum has been measured with the TOF-ΔE method and zero degree detectors. The half life of 23Al is determined to be T1/2=(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 β+ 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 β+ delayed proton decay has been identified at Ex=8.916MeV,and their relative intensity also been obtained.
