| 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 Ed greater than or equal 2.688MeV, three low excitation energy levels of 20Na with Ed = 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 Ed = 0.890 and 1.054, 2.424 and 2.457MeV. |
