摘要：

The beta-delayed particle emission from Mg-21 was studied at the Radioactive Ion Beam Line in Lanzhou (RIBLL1). Silicon array and high-purity germanium (HPGe) detectors were used to detect the charged particles and gamma-rays emitted from the decay. Half-life time of Mg-21 was determined to be 121.9(6) ms. New levels (5.639(26) MeV and 6.644(34) MeV) in the nucleus Na-21 were observed. An improved proton spectrum coincident with gamma-rays at 1.633MeV was obtained. A new partial decay scheme was constructed based on the present measurement.
