英文摘要	The in-beam measurement of β⁺ delay a decay of ²⁰Na on the Radioactive Ion Beam Line in Lanzhou(RIBLL) is reported. The radioactive ion ²⁰Na was identified in-beam by means of TOF - ΔE method. The implantation depth of the secondary beam in the detectors was optimized by a group of degraders with different thickness. The procedure of data acquisition was divided into two stages, i. e., in-beam and off-beam stage, to record the RIB and the β⁺ delay α particles respectively. Four resonant energy levels, 2.69, 3.09, 4.74, and 5.54MeV of ²⁰Ne, have been observed with their relative amplitudes of 100, 4.15, 1.10 and 15.2, respectively. The half-life of ²⁰Na->^β+20Ne*-> ¹⁶O+ α decay is preliminarily determined to be 459ms by using a time sealer combined with a pulse generator. The results are in good agreement with the ones of other group.
