英文摘要	Through the ²⁰Na ^β+-> ²⁰Ne* -> ¹⁶O + α process, the half-life and β⁺ delayed α decay spectrum of ²⁰Na have been measured on the Radioactive Ion Beam Line in Lanzhou (RIBLL). The ²⁰Na was identified through TOF-ΔE method and alpha particle was measured by four Si(Au) surface barrier detectors. The half life of ²⁰Na is(459 ± 7)ms. Result shows that in addition to nine high excitation energy levels with E_d greater than or equal 2.688MeV, three low excitation energy levels of ²⁰Na with E_d = 0.890 and 1.054, 1.991, 2.424 and 2.457MeV were observed in the experiment. The relative intensity for 1.991MeV level, a more important energy level in the center of mass system energy region from 1.6 to 2.5MeV obtained in this experiment is much higher than the existed one. We also obtained the relative intensities of the levels of E_d = 0.890 and 1.054, 2.424 and 2.457MeV.
