Abstract：
The β⁺ delay proton decay spectrum has been measured with TOF-ΔE method and zero degree detectors at the radioactive ion beam line in Lanzhou. The half life of 23 Al was determined to be T_1/2=(476±45)ms by using a time scaler cornbined with the precision pulse generator, which is consistent with the other group's result of (470±30)ms. The known β⁺ delay protons at E_d=0.216,0.278,0.438,0.479MeV have been observed in the experiment. A new energy level of23Mg at E_x=8.916MeV was found in the β⁺ delay proton decay of 23 Al, and their relative intensity was also determined.
