| 英文摘要 | Through the Na-20 (beta (+))under right arrow(20)Ne*--> O-16+ alphaa process, the half-life and beta (+) delayed a decay spectrum of Na-20 have been measured on the Radioactive Ion Beam Line in Lanzhou (RIBLL). The Na-20 was identified through TOF-DeltaE method and alpha particle was measured by four Si(Au) surface barrier detectors. The half life of Na-20 is(459 +/-7)ms. Result shows that in addition to nine high excitation energy levels with E(d)greater than or equal to2.688MeV, three low excitation energy levels of Na-20 with E-d = 0.890 & 1.054, 1.991, 2.424 & 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 & 1.054, 2.424 & 2.457MeV. |
